viral Long-Acting BMS-378806 Analogues Stabilize the State-1 Conformation of the Human Immunodeficiency Virus Type 1 Envelope Glycoproteins [Vaccines and Antiviral Agents] By jvi.asm.org Published On :: 2020-05-04T08:00:46-07:00 During human immunodeficiency virus type 1 (HIV-1) entry into cells, the viral envelope glycoprotein (Env) trimer [(gp120/gp41)3] binds the receptors CD4 and CCR5 and fuses the viral and cell membranes. CD4 binding changes Env from a pretriggered (state-1) conformation to more open downstream conformations. BMS-378806 (here called BMS-806) blocks CD4-induced conformational changes in Env important for entry and is hypothesized to stabilize a state-1-like Env conformation, a key vaccine target. Here, we evaluated the effects of BMS-806 on the conformation of Env on the surface of cells and virus-like particles. BMS-806 strengthened the labile, noncovalent interaction of gp120 with the Env trimer, enhanced or maintained the binding of most broadly neutralizing antibodies, and decreased the binding of poorly neutralizing antibodies. Thus, in the presence of BMS-806, the cleaved Env on the surface of cells and virus-like particles exhibits an antigenic profile consistent with a state-1 conformation. We designed novel BMS-806 analogues that stabilized the Env conformation for several weeks after a single application. These long-acting BMS-806 analogues may facilitate enrichment of the metastable state-1 Env conformation for structural characterization and presentation to the immune system. IMPORTANCE The envelope glycoprotein (Env) spike on the surface of human immunodeficiency virus type 1 (HIV-1) mediates the entry of the virus into host cells and is also the target for antibodies. During virus entry, Env needs to change shape. Env flexibility also contributes to the ability of HIV-1 to evade the host immune response; many shapes of Env raise antibodies that cannot recognize the functional Env and therefore do not block virus infection. We found that an HIV-1 entry inhibitor, BMS-806, stabilizes the functional shape of Env. We developed new variants of BMS-806 that stabilize Env in its natural state for long periods of time. The availability of such long-acting stabilizers of Env shape will allow the natural Env conformation to be characterized and tested for efficacy as a vaccine. Full Article
viral T Cell Responses Induced by Attenuated Flavivirus Vaccination Are Specific and Show Limited Cross-Reactivity with Other Flavivirus Species [Vaccines and Antiviral Agents] By jvi.asm.org Published On :: 2020-05-04T08:00:46-07:00 Members of the flavivirus genus share a high level of sequence similarity and often circulate in the same geographical regions. However, whether T cells induced by one viral species cross-react with other related flaviviruses has not been globally addressed. In this study, we tested pools of epitopes derived from dengue (DENV), Zika (ZIKV), Japanese encephalitis (JEV), West Nile (WNV), and yellow fever (YFV) viruses by intracellular cytokine staining (ICS) using peripheral blood mononuclear cells (PBMCs) of individuals naturally exposed to DENV or immunized with DENV (TV005) or YF17D vaccine. CD8 T cell responses recognized epitopes from multiple flaviviruses; however, the magnitude of cross-reactive responses was consistently severalfold lower than those to the autologous epitope pools and was associated with lower expression of activation markers such as CD40L, CD69, and CD137. Next, we characterized the antigen sensitivity of short-term T cell lines (TCL) representing 29 different individual epitope/donor combinations. TCL derived from DENV monovalent vaccinees induced CD8 and CD4 T cells that cross-reacted within the DENV serocomplex but were consistently associated with >100-fold-lower antigen sensitivity for most other flaviviruses, with no cross-recognition of YFV-derived peptides. CD8 and CD4 TCL from YF17D vaccinees were associated with very limited cross-reactivity with any other flaviviruses and in five out of eight cases >1,000-fold-lower antigen sensitivity. Overall, our data suggest limited cross-reactivity for both CD4 and CD8 T cell responses between flaviviruses and have implications for understanding immunity elicited by natural infection and strategies to develop live attenuated vaccines against flaviviral species. IMPORTANCE The envelope (E) protein is the dominant target of neutralizing antibodies for dengue virus (DENV) and yellow fever virus (YFV). Accordingly, several DENV vaccine constructs use the E protein in a live attenuated vaccine format, utilizing a backbone derived from a heterologous flavivirus (such as YF) as a delivery vector. This backbone comprises the nonstructural (NS) and capsid (C) antigens, which are dominant targets of T cell responses. Here, we demonstrate that cross-reactivity at the level of T cell responses among different flaviviruses is very limited, despite high levels of sequence homology. Thus, the use of heterologous flavivirus species as a live attenuated vaccine vector is not likely to generate optimal T cell responses and might thus impair vaccine performance. Full Article
viral Priming of Antiviral CD8 T Cells without Effector Function by a Persistently Replicating Hepatitis C-Like Virus [Pathogenesis and Immunity] By jvi.asm.org Published On :: 2020-05-04T08:00:46-07:00 Immune-competent animal models for the hepatitis C virus (HCV) are nonexistent, impeding studies of host-virus interactions and vaccine development. Experimental infection of laboratory rats with a rodent hepacivirus isolated from Rattus norvegicus (RHV) is a promising surrogate model due to its recapitulation of HCV-like chronicity. However, several aspects of rat RHV infection remain unclear, for instance, how RHV evades host adaptive immunity to establish persistent infection. Here, we analyzed the induction, differentiation, and functionality of RHV-specific CD8 T cell responses that are essential for protection against viral persistence. Virus-specific CD8 T cells targeting dominant and subdominant major histocompatibility complex class I epitopes proliferated considerably in liver after RHV infection. These populations endured long term yet never acquired antiviral effector functions or selected for viral escape mutations. This was accompanied by the persistent upregulation of programmed cell death-1 and absent memory cell formation, consistent with a dysfunctional phenotype. Remarkably, transient suppression of RHV viremia with a direct-acting antiviral led to the priming of CD8 T cells with partial effector function, driving the selection of a viral escape variant. These data demonstrate an intrinsic abnormality within CD8 T cells primed by rat RHV infection, an effect that is governed at least partially by the magnitude of early virus replication. Thus, this model could be useful in investigating mechanisms of CD8 T cell subversion, leading to the persistence of hepatotropic pathogens such as HCV. IMPORTANCE Development of vaccines against hepatitis C virus (HCV), a major cause of cirrhosis and cancer, has been stymied by a lack of animal models. The recent discovery of an HCV-like rodent hepacivirus (RHV) enabled the development of such a model in rats. This platform recapitulates HCV hepatotropism and viral chronicity necessary for vaccine testing. Currently, there are few descriptions of RHV-specific responses and why they fail to prevent persistent infection in this model. Here, we show that RHV-specific CD8 T cells, while induced early at high magnitude, do not develop into functional effectors capable of controlling virus. This defect was partially alleviated by short-term treatment with an HCV antiviral. Thus, like HCV, RHV triggers dysfunction of virus-specific CD8 T cells that are vital for infection resolution. Additional study of this evasion strategy and how to mitigate it could enhance our understanding of hepatotropic viral infections and lead to improved vaccines and therapeutics. Full Article

viral SARS-CoV-2 and ORF3a: Nonsynonymous Mutations, Functional Domains, and Viral Pathogenesis By msystems.asm.org Published On :: 2020-05-05T07:30:12-07:00 ABSTRACT The effect of the rapid accumulation of nonsynonymous mutations on the pathogenesis of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is not yet known. The 3a protein is unique to SARS-CoV and is essential for disease pathogenesis. Our study aimed at determining the nonsynonymous mutations in the 3a protein in SARS-CoV-2 and determining and characterizing the protein’s structure and spatial orientation in comparison to those of 3a in SARS-CoV. A total of 51 different nonsynonymous amino acid substitutions were detected in the 3a proteins among 2,782 SARS-CoV-2 strains. We observed microclonality within the ORF3a gene tree defined by nonsynonymous mutations separating the isolates into distinct subpopulations. We detected and identified six functional domains (I to VI) in the SARS-CoV-2 3a protein. The functional domains were linked to virulence, infectivity, ion channel formation, and virus release. Our study showed the importance of conserved functional domains across the species barrier and revealed the possible role of the 3a protein in the viral life cycle. Observations reported in this study merit experimental confirmation. IMPORTANCE At the surge of the coronavirus disease 2019 (COVID-19) pandemic, we detected and identified six functional domains (I to VI) in the SARS-CoV-2 3a protein.

viral A Qualitative Assessment of Provider and Client Experiences With 3- and 6-Month Dispensing Intervals of Antiretroviral Therapy in Malawi By ghspjournal.org Published On :: 2020-03-31T15:28:55-07:00 ABSTRACTIntroduction:Multimonth dispensing (MMD) of antiretroviral therapy (ART) is a differentiated model of care that can help overcome health system challenges and reduce the burden of HIV care on clients. Although 3-month dispensing has been the standard of care, interest has increased in extending refill intervals to 6 months. We explored client and provider experiences with MMD in Malawi as part of a cluster randomized trial evaluating 3- versus 6-month ART dispensing.Methods:Semi-structured in-depth interviews were conducted with 17 ART providers and 62 stable, adult clients with HIV on ART. Clients and providers were evenly divided by arm and were eligible for an interview if they had been participating in the study for 1 year (clients) or 6 months (providers). Questions focused on perceived challenges and benefits of the 3- or 6-month amount of ART dispensing. Interviews were transcribed, and data were coded and analyzed using constant comparison.Results:Both clients and providers reported that the larger medication supply had benefits. Clients reported decreased costs due to less frequent travel to the clinic and increased time for income-generating activities. Clients in the 6-month dispensing arm reported a greater sense of personal freedom and normalcy. Providers felt that the 6-month dispensing interval reduced their workload. They also expressed concerned about clients' challenges with ART storage at home, but clients reported no storage problems. Although providers mentioned the potential risk of clients sharing the larger medication supply with family or friends, clients emphasized the value of ART and reported only rare, short-term sharing, mostly with their spouses. Providers mentioned clients' lack of motivation to seek care for illnesses that might occur between refill appointments.Conclusions:The 6-month ART dispensing arm was particularly beneficial to clients for decreased costs, increased time for income generation, and a greater sense of normalcy. Providers' concerns about storage, sharing, and return visits to the facility did not emerge in client interviews. Further data are needed on the feasibility of implementing a large-scale program with 6-month dispensing. Full Article
viral Antiviral Properties and Mechanism of Action Studies of the Hepatitis B Virus Capsid Assembly Modulator JNJ-56136379 [Antiviral Agents] By aac.asm.org Published On :: 2020-04-21T08:01:10-07:00 Capsid assembly is a critical step in the hepatitis B virus (HBV) life cycle, mediated by the core protein. Core is a potential target for new antiviral therapies, the capsid assembly modulators (CAMs). JNJ-56136379 (JNJ-6379) is a novel and potent CAM currently in phase II trials. We evaluated the mechanisms of action (MOAs) and antiviral properties of JNJ-6379 in vitro. Size exclusion chromatography and electron microscopy studies demonstrated that JNJ-6379 induced the formation of morphologically intact viral capsids devoid of genomic material (primary MOA). JNJ-6379 accelerated the rate and extent of HBV capsid assembly in vitro. JNJ-6379 specifically and potently inhibited HBV replication; its median 50% effective concentration (EC50) was 54 nM (HepG2.117 cells). In HBV-infected primary human hepatocytes (PHHs), JNJ-6379, when added with the viral inoculum, dose-dependently reduced extracellular HBV DNA levels (median EC50 of 93 nM) and prevented covalently closed circular DNA (cccDNA) formation, leading to a dose-dependent reduction of intracellular HBV RNA levels (median EC50 of 876 nM) and reduced antigen levels (secondary MOA). Adding JNJ-6379 to PHHs 4 or 5 days postinfection reduced extracellular HBV DNA and did not prevent cccDNA formation. Time-of-addition PHH studies revealed that JNJ-6379 most likely interfered with postentry processes. Collectively, these data demonstrate that JNJ-6379 has dual MOAs in the early and late steps of the HBV life cycle, which is different from the MOA of nucleos(t)ide analogues. JNJ-6379 is in development for chronic hepatitis B treatment and may translate into higher HBV functional cure rates. Full Article
viral An Individual Participant Data Population Pharmacokinetic Meta-analysis of Drug-Drug Interactions between Lumefantrine and Commonly Used Antiretroviral Treatment [Clinical Therapeutics] By aac.asm.org Published On :: 2020-04-21T08:01:10-07:00 Treating malaria in HIV-coinfected individuals should consider potential drug-drug interactions. Artemether-lumefantrine is the most widely recommended treatment for uncomplicated malaria globally. Lumefantrine is metabolized by CYP3A4, an enzyme that commonly used antiretrovirals often induce or inhibit. A population pharmacokinetic meta-analysis was conducted using individual participant data from 10 studies with 6,100 lumefantrine concentrations from 793 nonpregnant adult participants (41% HIV-malaria-coinfected, 36% malaria-infected, 20% HIV-infected, and 3% healthy volunteers). Lumefantrine exposure increased 3.4-fold with coadministration of lopinavir-ritonavir-based antiretroviral therapy (ART), while it decreased by 47% with efavirenz-based ART and by 59% in the patients with rifampin-based antituberculosis treatment. Nevirapine- or dolutegravir-based ART and malaria or HIV infection were not associated with significant effects. Monte Carlo simulations showed that those on concomitant efavirenz or rifampin have 49% and 80% probability of day 7 concentrations <200 ng/ml, respectively, a threshold associated with an increased risk of treatment failure. The risk of achieving subtherapeutic concentrations increases with larger body weight. An extended 5-day and 6-day artemether-lumefantrine regimen is predicted to overcome these drug-drug interactions with efavirenz and rifampin, respectively. Full Article
viral Thiostrepton Reactivates Latent HIV-1 through the p-TEFb and NF-{kappa}B Pathways Mediated by Heat Shock Response [Antiviral Agents] By aac.asm.org Published On :: 2020-04-21T08:01:10-07:00 Antiretroviral therapy (ART) suppresses HIV-1 replication but fails to cure the infection. The presence of an extremely stable viral latent reservoir, primarily in resting memory CD4+ T cells, remains a major obstacle to viral eradication. The "shock and kill" strategy targets these latently infected cells and boosts immune recognition and clearance, and thus, it is a promising approach for an HIV-1 functional cure. Although some latency-reversing agents (LRAs) have been reported, no apparent clinical progress has been made, so it is still vital to seek novel and effective LRAs. Here, we report that thiostrepton (TSR), a proteasome inhibitor, reactivates latent HIV-1 effectively in cellular models and in primary CD4+ T cells from ART-suppressed individuals ex vivo. TSR does not induce global T cell activation, severe cytotoxicity, or CD8+ T cell dysfunction, making it a prospective LRA candidate. We also observed a significant synergistic effect of reactivation when TSR was combined with JQ1, prostratin, or bryostatin-1. Interestingly, six TSR analogues also show reactivation abilities that are similar to or more effective than that of TSR. We further verified that TSR upregulated expression of heat shock proteins (HSPs) in CD4+ T cells, which subsequently activated positive transcriptional elongation factor b (p-TEFb) and NF-B signals, leading to viral reactivation. In summary, we identify TSR as a novel LRA which could have important significance for applications to an HIV-1 functional cure in the future. Full Article
viral A Novel Inhaled Dry-Powder Formulation of Ribavirin Allows for Efficient Lung Delivery in Healthy Participants and Those with Chronic Obstructive Pulmonary Disease in a Phase 1 Study [Antiviral Agents] By aac.asm.org Published On :: 2020-04-21T08:01:10-07:00 Chronic obstructive pulmonary disease (COPD) is an inflammatory lung condition, causing progressive decline in lung function leading to premature death. Acute exacerbations in COPD patients are predominantly associated with respiratory viruses. Ribavirin is a generic broad-spectrum antiviral agent that could be used for treatment of viral respiratory infections in COPD. Using the Particle Replication In Nonwetting Templates (PRINT) technology, which produces dry-powder particles of uniform shape and size, two new inhaled formulations of ribavirin (ribavirin-PRINT-CFI and ribavirin-PRINT-IP) were developed for efficient delivery to the lung and to minimize bystander exposure. Ribavirin-PRINT-CFI was well tolerated in healthy participants after single dosing and ribavirin-PRINT-IP was well tolerated in healthy and COPD participants after single and repeat dosing. Ribavirin-PRINT-CFI was replaced with ribavirin-PRINT-IP since the latter formulation was found to have improved physicochemical properties and it had a higher ratio of active drug to excipient per unit dose. Ribavirin concentrations were measured in lung epithelial lining fluid in both healthy and COPD participants and achieved target concentrations. Both formulations were rapidly absorbed with approximately dose proportional pharmacokinetics in plasma. Exposure to bystanders was negligible based on both the plasma and airborne ribavirin concentrations with the ribavirin-PRINT-IP formulation. Thus, ribavirin-PRINT-IP allowed for an efficient and convenient delivery of ribavirin to the lungs while minimizing systemic exposure. Further clinical investigations would be required to demonstrate ribavirin-PRINT-IP antiviral characteristics and impact on COPD viral-induced exacerbations. (The clinical trials discussed in this study have been registered at ClinicalTrials.gov under identifiers NCT03243760 and NCT03235726.) Full Article
viral Discordance between Etravirine Phenotype and Genotype-Based Predicted Phenotype for Subtype C HIV-1 from First-Line Antiretroviral Therapy Failures in South Africa [Antiviral Agents] By aac.asm.org Published On :: 2020-04-21T08:01:09-07:00 Etravirine (ETR) is a nonnucleoside reverse transcriptase inhibitor (NNRTI) used in treatment-experienced individuals. Genotypic resistance test-interpretation systems can predict ETR resistance; however, genotype-based algorithms are derived primarily from HIV-1 subtype B and may not accurately predict resistance in non-B subtypes. The frequency of ETR resistance among recombinant subtype C HIV-1 and the accuracy of genotypic interpretation systems were investigated. HIV-1LAI containing full-length RT from HIV-1 subtype C-positive individuals experiencing virologic failure (>10,000 copies/ml and >1 NNRTI resistance-associated mutation) were phenotyped for ETR susceptibility. Fold change (FC) was calculated against a composite 50% effective concentration (EC50) from treatment-naive individuals and three classifications were assigned: (i) <2.9-FC, susceptible; (ii) ≥2.9- to 10-FC, partially resistant; and (iii) >10-FC, fully resistant. The Stanford HIVdb-v8.4 was used for genotype predictions merging the susceptible/potential low-level and low-level/intermediate groups for 3 x 3 comparison. Fifty-four of a hundred samples had reduced ETR susceptibility (≥2.9-FC). The FC correlated with HIVdb-v8.4 (Spearman’s rho = 0.62; P < 0.0001); however, 44% of samples were partially (1 resistance classification difference) and 4% completely discordant (2 resistance classification differences). Of the 34 samples with an FC of >10, 26 were HIVdb-v8.4 classified as low-intermediate resistant. Mutations L100I, Y181C, or M230L were present in 27/34 (79%) of samples with an FC of >10 but only in 2/46 (4%) of samples with an FC of <2.9. No other mutations were associated with ETR resistance. Viruses containing the mutation K65R were associated with reduced ETR susceptibility, but 65R reversions did not increase ETR susceptibility. Therefore, genotypic interpretation systems were found to misclassify ETR susceptibility in HIV-1 subtype C samples. Modifications to genotypic algorithms are needed to improve the prediction of ETR resistance for the HIV-1 subtype C. Full Article
viral Antiviral Activity of a Llama-Derived Single-Domain Antibody against Enterovirus A71 [Antiviral Agents] By aac.asm.org Published On :: 2020-04-21T08:01:09-07:00 In the past few decades, enterovirus A71 (EVA71) has caused devastating outbreaks in the Asia-Pacific region, resulting in serious sequelae in infected young children. No preventive or therapeutic interventions are currently available for curing EVA71 infection, highlighting a great unmet medical need for this disease. Here, we showed that one novel single-domain antibody (sdAb), F1, isolated from an immunized llama, could alleviate EVA71 infection both in vitro and in vivo. We also confirmed that the sdAb clone F1 recognizes EVA71 through a novel conformational epitope comprising the highly conserved region of VP3 capsid protein by using competitive-binding and overlapping-peptide enzyme-linked immunosorbent assays (ELISAs). Because of the virion’s icosahedral structure, we reasoned that adjacent epitopes must be clustered within molecular ranges that may be simultaneously bound by an engineered antibody with multiple valency. Therefore, two single-domain binding modules (F1) were fused to generate an sdAb-in-tandem design so that the capture of viral antigens could be further increased by valency effects. We showed that the tetravalent construct F1xF1-hFc, containing two sdAb-in-tandem on a fragment crystallizable (Fc) scaffold, exhibits more potent neutralization activity against EVA71 than does the bivalent sdAb F1-hFc by at least 5.8-fold. We also demonstrated that, using a human scavenger receptor class B member 2 (hSCARB2) transgenic mouse model, a half dose of the F1xF1-hFc provided better protection against EVA71 infection than did the F1-hFc. Thus, our study furnishes important insights into multivalent sdAb engineering against viral infection and provides a novel strategic deployment approach for preparedness of emerging infectious diseases such as EVA71.

viral I’m an Investigative Journalist. These Are the Questions I Asked About the Viral “Plandemic” Video.

Sign up to receive our biggest stories as soon as they’re published. The links to the viral video “Plandemic” started showing up in my Facebook feed Wednesday. “Very interesting,” one of my friends wrote about it. I saw several subsequent posts about it, and then my brother texted me, “Got a sec?” My brother is a pastor in Colorado and had someone he respects urge him to watch “Plandemic,” a 26-minute video that promises to reveal the “hidden agenda” behind the COVID-19 pandemic. I called him and he shared his concern: People seem to be taking the conspiracy theories presented in “Plandemic” seriously. He wondered if I could write something up that he could pass along to them, to help people distinguish between sound reporting and conspiracy thinking or propaganda. So I watched “Plandemic.” I did not find it credible, as I will explain below. YouTube, Facebook and Vimeo have since removed it from their platforms for violating their guidelines. Now it’s available on its own site. Sensational videos, memes, rants and more about COVID-19 are likely to keep coming. With society polarized and deep distrust of the media, the government and other institutions, such content is a way for bad actors to sow discord, mostly via social media. We saw it with Russia in the 2016 election and we should expect it to continue. But what surprised me is how easily “Plandemic” sank its hooks into some of my friends. My brother also felt alarmed that his own church members and leaders in other churches might be tempted to buy into it. The purpose of this column is not to skewer “Plandemic.” My goal is to offer some criteria for sifting through all the content we see every day, so we can tell the difference between fair reporting and something so biased it should not be taken seriously. Here’s a checklist, some of which I shared with my friends on Facebook, to help interrogate any content — and that includes what we publish at ProPublica. Is the Presentation One-Sided? There’s never just one side to a story. I mentioned this point in 2018 when I wrote about my faith and the biblical basis for investigative reporting. One of my favorite Proverbs says, “The first to state his case seems right until another comes and cross-examines him.” So a fair presentation should at least acknowledge opposing points of view. I didn’t see this in “Plandemic,” so I called the filmmaker, Mikki Willis, who is also the film’s narrator, to ask him whether I had somehow missed the other side of the argument. I had not. “The other side of the argument plays 24/7 on every screen in every airport and on every phone and in every home,” Willis said. “The people are only seeing one side of the story all the time. This is the other side of the story. This is not a piece that’s intended to be perfectly balanced.” I asked Willis if it was fair to call his film “propaganda,” which the Oxford dictionary defines as “information, especially of a biased or misleading nature, used to promote or publicize a particular political cause or point of view.” He said he doesn’t feel there’s anything misleading in his film, but otherwise the definition fits. And based on that definition he feels 100% of news reporting is propaganda. “What isn’t propaganda these days?” he asked. “In that sense, what we’re doing is fighting fire with fire.” Is There an Independent Pursuit of the Truth? The star of “Plandemic,” medical researcher Judy Mikovits, is controversial. The magazine Science reports that it published and then retracted one of her papers in 2011. A search warrant provided to ProPublica by one of her former attorneys shows she was fired from her position at Whittemore Peterson Institute, a research center in Nevada, in September 2011. Then she allegedly stole notebooks and a laptop computer from the Institute, the search warrant said, leading to an arrest warrant for alleged possession of stolen property and unlawful taking of computer data. She was arrested on Nov. 18, 2011, but denied wrongdoing. The charges were dropped. But “Plandemic” ignores or brushes past these facts and portrays her as an embattled whistleblower. “So you made a discovery that conflicted with the agreed-upon narrative?” Willis says to Mikovits, introducing her as a victim. “And for that, they did everything in their powers to destroy your life.” A typical viewer is not going to know the details about Mikovits’ background. But as the primary source of controversial information being presented as fact, it’s worth an online search. The fact-checking site PolitiFact details her arrest and criminal charges. Clearly, there’s more to her story than what’s presented in “Plandemic.” That should give us pause when we assess its credibility. Is There a Careful Adherence to the Facts? In “Plandemic,” Willis asks Mikovits about her arrest: “What did they charge you with?” “Nothing,” she replies. “I was held in jail, with no charges.” Being charged with a crime is one of those concrete facts that we can check out. Science magazine reported Mikovits’ arrest and felony charge. I also found a civil lawsuit she filed against the Whittemore Peterson Institute in 2014 in the U.S. District Court for the Southern District of California. “Mikovits was arrested on criminal charges…” her complaint says in the case, which was eventually dismissed. I asked Willis about the apparent discrepancy, where she said in his film that she wasn’t charged, when court documents show that she was charged. After my inquiry, he said he spoke to Mikovits and now feels it is clear that she meant that the charges were dropped. I tracked down Mikovits and she said what she meant in the film is that there were no charges of any type of wrongdoing that would have led to her being charged with being a fugitive from justice. She admitted that all the controversy has been hard for her to sort out. “I’ve been confused for a decade,” she told me. She said she would try to be more clear in the future when she talks about the criminal charge: “I’ll try to learn to say it differently,” she said. This underscores the importance of careful verification, and it distinguishes the craft of journalism from other forms of information sharing. People often speak imprecisely when they’re telling their stories. It’s our duty to nail down precisely what they do and do not mean, and verify it independently. If we don’t, we risk undermining their credibility and ours. That’s in part why we at ProPublica and many other journalists often link directly to our underlying source documents, so you can verify the information yourself. Are Those Accused Allowed to Respond? Dr. Anthony Fauci, director of the National Institute of Allergy and Infectious Diseases, is one of the nation’s leaders in the response to the coronavirus. In “Plandemic,” Mikovits accuses Fauci of a cover-up and of paying off people who perpetrate fraud, among other things. PolitiFact found no evidence to support the allegations against Fauci. Every time I write a story that accuses someone of wrongdoing I call them and urge them to explain the situation from their perspective. This is standard in mainstream journalism. Sometimes I’ve gone to extreme lengths to get comments from someone who will be portrayed unfavorably in my story — traveling to another state and showing up at their office and their home and leaving a note if they are not there to meet me. “Plandemic” doesn’t indicate whether the filmmakers reached out to Fauci for his version of the story. So I asked Willis about it. “We did not,” he told me. Are All Sources Named and Cited, and if Not, Is the Reason Explained? All sources should be identified, with their credentials, so viewers can verify their expertise or possible biases. If they can’t be for some reason, then that should be explained. “Plandemic” features unnamed people in medical scrubs, presented as doctors, saying they’re being wrongly pressured to add COVID-19 on people’s death certificates or are not being allowed to use the drug hydroxychloroquine to treat patients. But the speakers are not named, so we can’t really tell who they are, or even if they are doctors at all. That makes it impossible to tell if they are credible. I asked Willis why he didn’t name those people. He told me he was in a hurry to release the 26-minute version of “Plandemic,” but the doctors will be named in the final version. “We should have done that,” he said. Does the Work Claim Some Secret Knowledge? “Plandemic” calls itself a documentary that reveals “the hidden agenda behind COVID-19.” We are in the midst of a global pandemic where few people in the world can figure out what is happening or the right way to respond, let alone agendas. We have almost every journalist in the country writing about this. And if the truth about a conspiracy is out there, many people have an incentive to share it. But “Plandemic” would like us to think it’s presenting some exclusive bit of secret knowledge that is going to get at the real story. That’s not likely. Plus, to be honest, there were so many conspiratorial details stacked on top of each other in the film I couldn’t keep them straight. When I spoke to Willis I told him I was having a hard time understanding his point. Then I took a stab at what I thought was the main thrust of his argument. “Are you saying that powerful people planned the pandemic and made it happen so they could get rich by making everyone get vaccines?” I asked. It turns out Willis isn’t sure either. “We’re in the exploratory phase,” he told me. “I don’t know, to be clear, if it’s an intentional or naturally occurring situation. I have no idea.” Then he went on to say that the pandemic is being politicized and used to take away our civil liberties and leverage other political policies. “Certain forces” have latched onto the situation, he said. “It’s too fishy.” He had me at, “I have no idea.” That sums it up. This is a vast pandemic and massive catastrophe. Our country wasn’t prepared for it, and the response by our top leaders has been disjointed. We’re restricted to our homes. Many people have lost their jobs and some are afraid or sick or dying. That makes us vulnerable to exploitation by people who will present inaccurate or intellectually dishonest information that promises to tell us the truth. Perhaps “Plandemic” is guilty of sloppy storytelling, or maybe people really do believe the things they’re saying in the video. Or perhaps they’re being intentionally dishonest, or it’s a biased connecting of the dots rooted in personal and professional grievances. I don’t know because I can’t get inside their heads to judge their motives. Ultimately, we’re all going to need to be more savvy consumers when it comes to information, no matter how slickly it’s presented. This may be but a signal of what’s to come in the run-up to the 2020 presidential election, when memes and ads of unknown origin come across our social media feeds. There are standards for judging the credibility of the media we take in every day, so let’s apply them. Full Article
