A Digital India Must Embrace the Circular Economy

A Digital India Must Embrace the Circular Economy Expert comment sysadmin 15 January 2018

A growing amount of e-waste should draw attention to the broader sustainability of a digital society.

The latest Global E-Waste Monitor places India as one of the highest contributors to global e-waste, generating over 2 million metric tonnes in 2016. Posing serious health and environmental risks, growing e-waste represents the hidden cost of increasingly digital lives in an information society.

With just 33 per cent of the population owning a smart phone, India already has the second largest number of smart phone users in the world, nearly 4 times that of the United States. The amount of e-waste generated will exponentially increase in the coming decade as the cost of consumer electronics decline, middle-class incomes rise, and the frequency at which devices are discarded increases.

As governance instruments are increasingly digitized and industry re-repositions itself to leverage Industry 4.0 solutions, the generation of e-waste will become a byproduct of institutional choices rather than consumer consumption and behaviour alone.

India is already a leader in the management and recycling of e-waste. But over 90 per cent is managed in the unorganized sector by small businesses and individual entrepreneurs, typically from low-income marginalized communities, and often women. E-waste contains various toxic substances such as mercury and lead, prolonged exposure to which can lead to major health problems.

Almost 80 per cent of e-waste workers in India suffer from respiratory ailments due to improper standards and nearly 500,000 children are engaged in e-waste collection without adequate protection and safeguards. The bulk of the dirty and dangerous work supporting India’s march towards an increasingly digital society is done by those who have the least access to technology gains. Government regulations for the management of e-waste, on the other hand, are becoming more relaxed, presumably as a result of industry pressure. To streamline e-waste management, the government notified Electronic Waste Rules in 2011, based on the concept of extended producer responsibility (EPR).

EPR makes manufacturers of electronic products responsible for the end-of-life management of their products, including setting up collection centres. By shifting the burden to manufacturers, the EPR framework, in theory, creates incentives for more environmentally friendly design. But the impact of EPR rules on manufacturers has been minimal, at best. The recently released Draft Notification (2017) by the Ministry of Environment, Forest and Climate Change further relaxes the EPR rule by reducing the e-waste collection targets for industries.

While the efficiency and productivity gains of Digital India are to be welcomed, growing e-waste should draw attention to the broader sustainability of a digital society. Data centres, for example, are one the largest contributors to global warming, contributing a similar amount to global greenhouse emissions as the aviation industry.

This amount is expected to triple in the next decade. In many ways, the sustainability challenge is a ‘wicked problem’ – where possible solutions create a new set of additional challenges and the choice between available alternatives is largely about competing values.

For example, data centres powered by renewable sources of energy such as solar provide a greener alternative, but will also create new forms of e-waste in the form of photovoltaic cells and panels. An unverified estimate suggests that India’s projected solar capacity of 100 gigawatts by 2022 will create 7.76 million tonnes of e-waste. Without adequate and preemptive consideration of how this waste should be disposed and recycled, renewable energy solutions can create new negative externalities.

For Digital India to be sustainable, we need to develop anticipatory knowledge for preemptive solutions. It is an opportune moment to think of the broader architecture of a digital society, one that avoids getting locked into unsustainable models of production and consumption, as is the case with many industrialized economies.

The argument that such considerations are premature for India, given high levels of poverty and unemployment, are misplaced. Enquiries into the sustainability of Digital India are no less urgent than the need for sustained job-creating economic growth. These issues should not be addressed in a sequential or linear manner, but in parallel, or else we will be only partially aware of available choices and their consequences, creating new forms of technological and economic lock-ins.

The value-based choice demanded by the ‘wicked problem’ at hand is one that embraces the idea of a circular economy — one that departs from the linear economic growth model predicated on ‘take, make, dispose’ to embrace a growth model based on creating closed loops of production, consumption and re-use. A circular economy model is built on the idea of designing out waste and pollution; keeping products and materials in use; and regenerating natural systems. In many ways, India is already a leader in the circular economy.

Alongside, the management of e-waste and other forms of recycling, high levels of repair and reuse are distinctly observable. A number of reports note that the informal waste management sector in India works better than systems in many industrialized economies.

A circular economy vision for Digital India would include organizing informal waste management systems, including safety and social protection initiatives for workers; revising and tightening existent e-waste rules for increased accountability by manufacturers both in terms of durable design and responsible disposal; green data centres; and building future smart cities with a view towards energy and water efficiency, among others.

A recent report by the Ellen McArthur Foundation and the World Economic Forum also estimates that a circular economy path to development could bring India annual benefits of $624 billion by 2050. Greenhouse gas emissions could also be 44 per cent lower in 2050, compared with current development path.

Unsurprisingly, Nordic countries are leading the way in promoting the idea of a circular economy. Sweden recently announced tax breaks for repair related activities and Finland hosted the first global conference on the circular economy earlier this year. The circular economy provides an opportunity for India to capitalize and leverage an already existing culture of circular activities, and promote it as a policy agenda that will create new forms of employment while facilitating sustainable environmental management.

Can the world avoid a new nuclear arms race?

Can the world avoid a new nuclear arms race? 18 November 2024 — 6:00PM TO 7:00PM Anonymous (not verified) Chatham House and Online

Leading experts discuss how states are expanding nuclear arsenals amid rising geopolitical challenges.

Leading experts discuss how states are expanding nuclear arsenals amid rising geopolitical challenges.

The Doomsday Clock stands at 90 seconds to midnight – the closest to global catastrophe it has ever been. As geopolitical competition intensifies, nuclear risks are resurging at an alarming rate. The collapse of key arms control agreements, such as the Intermediate-Range Nuclear Forces (INF) Treaty, has removed crucial safeguards against arms races. Efforts to extend or replace existing treaties face significant hurdles in the current geopolitical climate.

Nuclear rhetoric has become more aggressive, as evidenced by Russian and North Korean nuclear threats. Several nuclear-armed states are also engaging in extensive modernization programmes of their nuclear arsenals, potentially fuelling a new arms race.

Despite these pressures, the number of nuclear possessor states has held steady so far. The ongoing Iranian efforts to build nuclear weapons is the closest attempt by a new state to acquire nuclear weapons. As the global security environment becomes more and more tense, existing nuclear possessor states increasingly rely on their nuclear weapons. This might threaten the global consensus against nuclear proliferation.

This session examines these competing pressures and propose strategies to reduce the risks of nuclear weapons use and proliferation. Our expert panel explores diplomatic initiatives, technical measures, and policy innovations to address these critical challenges.

This expert panel discusses key questions including:

  • Are we already in the middle of a global nuclear arms race?
  • How can international arms control treaties be negotiated in the current geopolitical environment?
  • Does a new US president change the nuclear calculus? Is the US still able to reassure allies of its ‘extended deterrence’?
  • How can we reduce the risk of additional proliferation? Which states might want to acquire nuclear weapons and what can we do about it?

The institute occupies a position of respect and trust, and is committed to fostering inclusive dialogue at all events. Event attendees are expected to uphold this by adhering to our code of conduct.

Peptidoglycan analysis reveals that synergistic deacetylase activity in vegetative Clostridium difficile impacts the host response [Glycobiology and Extracellular Matrices]

Clostridium difficile is an anaerobic and spore-forming bacterium responsible for 15–25% of postantibiotic diarrhea and 95% of pseudomembranous colitis. Peptidoglycan is a crucial element of the bacterial cell wall that is exposed to the host, making it an important target for the innate immune system. The C. difficile peptidoglycan is largely N-deacetylated on its glucosamine (93% of muropeptides) through the activity of enzymes known as N-deacetylases, and this N-deacetylation modulates host–pathogen interactions, such as resistance to the bacteriolytic activity of lysozyme, virulence, and host innate immune responses. C. difficile genome analysis showed that 12 genes potentially encode N-deacetylases; however, which of these N-deacetylases are involved in peptidoglycan N-deacetylation remains unknown. Here, we report the enzymes responsible for peptidoglycan N-deacetylation and their respective regulation. Through peptidoglycan analysis of several mutants, we found that the N-deacetylases PdaV and PgdA act in synergy. Together they are responsible for the high level of peptidoglycan N-deacetylation in C. difficile and the consequent resistance to lysozyme. We also characterized a third enzyme, PgdB, as a glucosamine N-deacetylase. However, its impact on N-deacetylation and lysozyme resistance is limited, and its physiological role remains to be dissected. Finally, given the influence of peptidoglycan N-deacetylation on host defense against pathogens, we investigated the virulence and colonization ability of the mutants. Unlike what has been shown in other pathogenic bacteria, a lack of N-deacetylation in C. difficile is not linked to a decrease in virulence.

Molecular architecture and domain arrangement of the placental malaria protein VAR2CSA suggests a model for carbohydrate binding [Glycobiology and Extracellular Matrices]

VAR2CSA is the placental-malaria–specific member of the antigenically variant Plasmodium falciparum erythrocyte membrane protein 1 (PfEMP1) family. It is expressed on the surface of Plasmodium falciparum-infected host red blood cells and binds to specific chondroitin-4-sulfate chains of the placental proteoglycan receptor. The functional ∼310 kDa ectodomain of VAR2CSA is a multidomain protein that requires a minimum 12-mer chondroitin-4-sulfate molecule for specific, high affinity receptor binding. However, it is not known how the individual domains are organized and interact to create the receptor-binding surface, limiting efforts to exploit its potential as an effective vaccine or drug target. Using small angle X-ray scattering and single particle reconstruction from negative-stained electron micrographs of the ectodomain and multidomain constructs, we have determined the structural architecture of VAR2CSA. The relative locations of the domains creates two distinct pores that can each accommodate the 12-mer of chondroitin-4-sulfate, suggesting a model for receptor binding. This model has important implications for understanding cytoadherence of infected red blood cells and potentially provides a starting point for developing novel strategies to prevent and/or treat placental malaria.

The UK’s Huawei Decision: Why the West is Losing the Tech Race

17 July 2020

Joyce Hakmeh

Senior Research Fellow, International Security Programme; Co-Editor, Journal of Cyber Policy
On 5G and the technological race, the answer is a visionary rather than a reactive approach and, so far, the West has opted for the latter.

GettyImages-1140107267.jpg

The UK’s decision to ban its mobile providers from buying new Huawei 5G equipment after December 2020 and removing all the company’s 5G kit from their networks by 2027 is a blow to Huawei and China, but it is one battle in a long war that the West is currently losing.

5G’s significance for the next generation of technology is indisputable and so is its critical role in helping countries achieve digital transformation and economic success. Not only does it offer faster and better connection speeds and greater capacity, it also transforms the way people interact with online services. And it will allow industry to automate and optimize processes that are not possible today.

Due to its transformative importance, what is in essence a technological issue has turned into a contest over global technological leadership that extends beyond the US-China rivalry and has created tensions between the US and its long-time allies. Yet 5G is just one key technology in a more expansive landscape that will underpin the future of the world’s critical infrastructure, including in areas such as quantum computing, biotechnology, artificial intelligence, the internet of things and big data.

To achieve technological leadership in these domains requires governments to invest in a long-term, strategic and agile vision that is able to encompass the interdependencies between these areas and then leverage the resulting technological advances for economic progress. It also requires governments working with each other and with the private sector to support research and development and to create companies with leading-edge technologies that can compete globally.

China understands this and has a national and international vision to establish itself as a technological superpower. Re-balancing from a hub of labour-intensive manufacturing to a global innovation powerhouse is the absolute priority of the ruling Chinese Communist Party.

China’s state-led approach

In the earlier part of this journey, commercial espionage and IP theft of western R&D were at the heart of the Chinese way of competing. Now, Beijing is cultivating national champions that can drive China’s technological innovation, with the goal of using domestic suppliers to reduce reliance on foreign technology at home as well as extending its international outreach. 

In the 5G area, Beijing has introduced domestically the so-called ‘New Infrastructure Investments Fund’, which earmarks special loans to boost 5G technology applications in medical devices, electric vehicles and communication platforms. This Fund constitutes a major part of the stimulus package for China’s post-COVID economic recovery.

Apart from 5G, China's recent launch of a second state-funded semiconductor development fund valued at $29 billion, following an earlier $20 billion fund for the same purpose, shows the extent to which state financial resources are being utilized in China’s quest to become technologically self-sufficient.

It is too early to know if the Chinese government’s industrial policies will eventually achieve the technological self-sufficiency Beijing has long desired. But its growing national capabilities have stoked serious concerns across the West and led to the current US administration’s determined effort to dismantle Chinese high-tech companies.

China’s approach to macroeconomic management diverges significantly from that of the US and other market economies, particularly in its policy towards driving innovation.  Due to the legacy of a state-planned economy, China is certain that simply relying on market forces is insufficient.

While Beijing financially supports government-controlled technological enterprises, Washington takes  a laissez-faire, light-touch approach by the state to the business sector. The US believes that a politicized process of distributing public money is inherently susceptible to rent-seeking and corruption, and gets in the way of competitive innovation. In line with most liberal economists, many Western governments believe the government should refrain from market intervention. For its part, Beijing stresses a state-dominated economy as a necessary precondition both to the future growth of the Chinese economy and to the legitimization of one-party rule. 

If the pro-market economists’ view is correct, the US should have little to fear from Chinese industrial innovation policy in the long-term. Let Beijing waste money and distort resource allocation, while Washington follows its private sector-led principles, confident that this approach will produce a more competitive economy in the long run.

Using the leverage of technical standards

But one area that should concern the US and that illustrates the Chinese vision for global technological dominance is technical standard setting. Technical standards determine how technologies work with each other, enabling their interoperability around the world, meaning they can function irrespective of where they are being used.

The Chinese leadership has long understood the relationship between technical standards and economic power. Standards help to monetize technological innovation and research and can help shape new technologies. China has therefore been playing an increasingly active role in international standards organizations to legitimize Chinese technologies, whereas the US, which historically has been highly influential in this area, has not been participating as much or as effectively.

China has also been using its Belt and Road Initiative (BRI) as an opportunity to internationalize the distribution of its standards to countries signed up to the BRI. The so-called Digital Silk Road, which has been described as China’s most important global governance initiative, acts as a route to accelerate this process. Later this year, China is expected to launch its new ‘China Standards 2035’ plan, which aims to shape how the next generation of technologies will work together.

China’s preferred model and its recent actions have given Western leaders much to worry about.  But standing up to China’s growing global influence in high technology and re-establishing the West’s desired technological edge will take much more than achieving a common front on excluding China from their 5G networks. It requires a long-term vision built on the power of competitive markets, backed by solid investment in the next generation of technology. This will require, in turn, much greater cooperation between Western governments and between them and their private sectors.

And, whilst recent protective steps taken in Washington and other Western capitals may slow down China’s trailblazing in the technology sphere, it will only hasten China's determination to become tech self-sufficient in the long term. This will increase the probability of a splintered internet, which will have negative repercussions for all.

Choosing Kamala Harris Puts Identity at the Heart of Presidential Race

12 August 2020

Dr Leslie Vinjamuri

Director, US and the Americas Programme; Dean, Queen Elizabeth II Academy for Leadership in International Affairs
Joe Biden’s choice of Kamala Harris as his running mate will have a lasting impact on how Americans think about the presidential ticket, and confirms the violent killing of George Floyd unleashed a demand for racial equality that continues to have dramatic impact.

2020-08-12-Kamala-Harris

Despite being such a historic selection, in certain aspects, Kamala Harris does not actually signal change. She is a moderate in the Democratic Party, an insider more than an outsider, and a highly experienced leader with national, state level and city level credentials. She worked as a district attorney in San Francisco for several years before being elected attorney general for the state of California, and then to the US Senate in 2016. Harris also stood as a candidate against Biden in the contest to become the Democratic Party's presidential candidate.

Like Joe Biden, she is a highly experienced leader with strong credentials. But California is solidly blue, so she cannot deliver a new state for him. In many ways she is a safe choice and — at a time when Biden is far ahead of Donald Trump in the polls and America faces a lot of uncertainty — many leading political analysts say safe is exactly what the Democratic candidate needs.

The 2020 US Presidential Elections and the State of the Nation

Amy Walter and Adam Boulton discuss the current state of the nation and what this means for the US presidential election.

But certainly as a signal to the American people, and the rest of the world, of what America is and what it stands for, the choice of Kamala Harris is truly historic. The senator from California is the first African-American woman, and the first Asian-American woman, on the presidential ticket. If Biden wins in November, Harris becomes the first female vice-president.

The historic aspects do not end there. Harris also represents a rapidly growing segment of the US population, but one that gets far less mention — multi-racial Americans. The exact size of America’s multi-racial population has been notoriously hard to measure, especially as it has only been 15 years since the US Census Bureau allowed Americans to choose more than one race when completing their census form. But America has long seen itself as a melting pot, so Harris’s place on the ballot underscores a national narrative with a deep resonance across the country, not least among America’s schoolchildren.

In recent weeks, it came to feel inevitable Biden would choose an African-American running mate. His selection comes at a time when more Americans than ever before have taken to the streets to protest the brutal killing of George Floyd and racial injustice. And the demand for racial equality has been accelerated by the COVID-19 pandemic which has disproportionately affected African-Americans who are dying from the virus at around double the rate of their white American counterparts, while twice the number of black businesses are closing relative to their white counterparts.

The choice of Harris also speaks to another fundamental aspect of the ‘American dream’. She is the daughter of two immigrant parents, her father being from Jamaica and her mother from India. Immigration has become one of the toughest issues in US politics, and immigrants have suffered repeated rhetorical attacks from Trump. One of Harris’s first stands in the US Senate was against President Trump’s entry ban to the US on several countries with majority Muslim populations.

When it comes to questions of identity, the choices that the US electorate now face in November could not be more stark. President Trump used the opportunity of the July 4 weekend to deliver a speech at Mount Rushmore which appeared to actively seek division and to ignite America’s cultural wars.

By choosing Kamala Harris, Biden also continues to signal that he will lead from the moderate wing of the Democratic Party.

Harris may be left of Biden, but she is far to the right of other well-known progressive candidates, especially Elizabeth Warren. She has not, for example, supported more far-reaching measures to redistribute wealth, especially the proposal for a wealth tax. And she has a track record of being tough on crime during her years as a prosecutor. Although she played an active role in recent protests and signalled her commitment to police reform and anti-lynching laws, not all young or progressive protesters will be easily persuaded by her credentials.

However, for voters who hoped for a more progressive candidate, two factors play to the advantage of the Biden-Harris ticket. This election still looks set to be a referendum on President Trump and — especially now — his ability to manage the public health and economic crises at home. And Biden has continued to include the progressive side of the Democratic Party in his plans, giving Bernie Sanders and Alexandria Ocasio-Cortez key roles in developing climate proposals, and establishing a series of Unity task forces to bring the party together.

There are also other more conventional factors at play. Biden has relied on the support of African-American and also female voters. While Harris may not broaden this support, it should help ensure these voters turn out — if primarily via their postal box — to vote for Biden. His choice of Kamala Harris answers the one big outstanding question facing his candidacy and signals the true beginning of the race to the White House.

Angiostatic cues from the matrix: Endothelial cell autophagy meets hyaluronan biology [Glycobiology and Extracellular Matrices]

The extracellular matrix encompasses a reservoir of bioactive macromolecules that modulates a cornucopia of biological functions. A prominent body of work posits matrix constituents as master regulators of autophagy and angiogenesis and provides molecular insight into how these two processes are coordinated. Here, we review current understanding of the molecular mechanisms underlying hyaluronan and HAS2 regulation and the role of soluble proteoglycan in affecting autophagy and angiogenesis. Specifically, we assess the role of proteoglycan-evoked autophagy in regulating angiogenesis via the HAS2-hyaluronan axis and ATG9A, a novel HAS2 binding partner. We discuss extracellular hyaluronan biology and the post-transcriptional and post-translational modifications that regulate its main synthesizer, HAS2. We highlight the emerging group of proteoglycans that utilize outside-in signaling to modulate autophagy and angiogenesis in cancer microenvironments and thoroughly review the most up-to-date understanding of endorepellin signaling in vascular endothelia, providing insight into the temporal complexities involved.

Clearance of intracellular tau protein from neuronal cells via VAMP8-induced secretion [Cell Biology]

In Alzheimer's disease (AD), tau, a microtubule-associated protein (MAP), becomes hyperphosphorylated, aggregates, and accumulates in the somato-dendritic compartment of neurons. In parallel to its intracellular accumulation in AD, tau is also released in the extracellular space, as revealed by its increased presence in cerebrospinal fluid (CSF). Consistent with this, recent studies, including ours, have reported that neurons secrete tau, and several therapeutic strategies aim to prevent the intracellular tau accumulation. Previously, we reported that late endosomes were implicated in tau secretion. Here, we explore the possibility of preventing intracellular tau accumulation by increasing tau secretion. Using neuronal models, we investigated whether overexpression of the vesicle-associated membrane protein 8 (VAMP8), an R-SNARE found on late endosomes, could increase tau secretion. The overexpression of VAMP8 significantly increased tau secretion, decreasing its intracellular levels in the neuroblastoma (N2a) cell line. Increased tau secretion by VAMP8 was also observed in murine hippocampal slices. The intracellular reduction of tau by VAMP8 overexpression correlated to a decrease of acetylated tubulin induced by tau overexpression in N2a cells. VAMP8 staining was preferentially found on late endosomes in N2a cells. Using total internal reflection fluorescence (TIRF) microscopy, the fusion of VAMP8-positive vesicles with the plasma membrane was correlated to the depletion of tau in the cytoplasm. Finally, overexpression of VAMP8 reduced the intracellular accumulation of tau mutants linked to frontotemporal dementia with parkinsonism and α-synuclein by increasing their secretion. Collectively, the present data indicate that VAMP8 could be used to increase tau and α-synuclein clearance to prevent their intracellular accumulation.

Novel Proteomic Profiling of Epididymal Extracellular Vesicles in the Domestic Cat Reveals Proteins Related to Sequential Sperm Maturation with Differences Observed between Normospermic and Teratospermic Individuals [Research]

Extracellular vesicles (EVs) secreted by the epididymal epithelium transfer to spermatozoa key proteins that are essential in promoting motility and subsequent fertilization success. Using the domestic cat model, the objectives were to (1) characterize and compare protein content of EVs between segments of the epididymis, and (2) compare EV protein compositions between normo- and teratospermic individuals (producing >60% of abnormal spermatozoa). Epididymal EVs from adult cats were isolated and assessed via liquid chromatography tandem MS. Both male types shared 3008 proteins in total, with 98 and 20 EV proteins unique to normospermic and teratospermic males, respectively. Expression levels of several proteins changed between epididymal segments in both male types. Several proteins in both groups were related to sperm motility (e.g. hexokinase 1, adenylate kinase isoenzyme) and zona pellucida or oolemma binding (e.g. disintegrin and metalloproteinase domain proteins, zona binding proteins 1 and 2). Interestingly, seven cauda-derived EV proteins trended downward in teratospermic compared with normospermic males, which may relate to poor sperm quality. Collective results revealed, for the first time, EV proteins related to sequential sperm maturation with differences observed between normospermic and teratospermic individuals.

A proteomic approach to understand the clinical significance of acute myeloid leukemia-derived extracellular vesicles reflecting essential characteristics of leukemia [Research]

Extracellular vesicle (EV) proteins from acute myeloid leukemia (AML) cell lines were analyzed using mass spectrometry. The analyses identified 2450 proteins, including 461 differentially expressed proteins (290 upregulated and 171 downregulated). CD53 and CD47 were upregulated and were selected as candidate biomarkers. The association between survival of patients with AML and the expression levels of CD53 and CD47 at diagnosis was analyzed using mRNA expression data from The Cancer Genome Atlas database. Patients with higher expression levels showed significantly inferior survival than those with lower expression levels. Enzyme-linked immunosorbent assay results of the expression levels of CD53 and CD47 from EVs in the bone marrow of patients with AML at diagnosis and at the time of complete remission with induction chemotherapy revealed that patients with downregulated CD53 and CD47 expression appeared to relapse less frequently. Network model analysis of EV proteins revealed several upregulated kinases, including LYN, CSNK2A1, SYK, CSK, and PTK2B. The potential cytotoxicity of several clinically applicable drugs that inhibit these kinases was tested in AML cell lines. The drugs lowered the viability of AML cells. The collective data suggest that AML-derived EVs could reflect essential leukemia biology.

What are the lessons from the UK’s COVID-19 vaccination campaign?

The first COVID-19 vaccination in the UK was administered on 8 December 2020, eight months after the World Health Organization (WHO) declared COVID-19 a pandemic on 11 March.

With multiple rounds of vaccines having now been administered widely, the UK is in a position to live effectively with the virus and the prospects of more lockdowns and COVID-19 restrictions have diminished.

The story behind the UK’s biggest vaccination campaign in British history is told during this discussion with Kate Bingham and Tim Hames, authors of The Long Shot: The Inside Story of the Race to Vaccinate Britain, which describes the management of complex political and operational challenges.

Juggling vaccine suppliers, Whitehall and the media, all had the potential to threaten the Vaccine Taskforce’s efforts.

This event explores the UK’s experience and lessons learned. The panel explore:

  • How were the most challenging obstacles to the UK’s vaccine development, scale-up and delivery overcome?
  • What does the success of the UK vaccine development and delivery mean in an international context?
  • What has the COVID-19 pandemic highlighted about global cooperation on vaccine administration worldwide?
  • As the pandemic moves into the rear-view mirror, how can industry and government work better together for future vaccination campaigns?

As with all members events, questions from the audience drive the conversation.
