WHO: Seven of the nine candidate COVID-19 vaccines already in clinical trials

Geneva/London: Seventy-five countries have submitted expressions of interest to protect their populations and those of other nations through joining the COVAX Facility, a mechanism designed to guarantee rapid, fair and equitable access to COVID-19 vaccines worldwide.

The 75 countries, which would finance the vaccines from their own public finance budgets, partner with up to 90 lower-income countries that could be supported through voluntary donations to Gavi’s COVAX Advance Market Commitment (AMC). Together, this group of up to 165 countries represents more than 60% of the world’s population. Among the group are representatives from every continent and more than half of the world’s G20 economies.

Gavi, the Vaccine Alliance is a public-private partnership that helps vaccinate half the world’s children against some of the world’s deadliest diseases. Since its inception in 2000, Gavi has helped to immunise a whole generation – over 760 million children – and prevented more than 13 million deaths, helping to halve child mortality in 73 developing countries. Gavi also plays a key role in improving global health security by supporting health systems as well as funding global stockpiles for Ebola, cholera, meningitis and yellow fever vaccines.

The countries submitting expressions of interest include Argentina, Armenia, Brazil, Canada, Czech Republic, Estonia, Finland, Iceland, Ireland, Israel, Japan, Kuwait, Luxembourg, Mauritius, Mexico, Monaco, Montenegro, New Zealand, North Macedonia, Norway, Portugal, Qatar, Republic of Korea, San Marino, Saudi Arabia, Switzerland, United Arab Emirates and the United Kingdom.

“COVAX is the only truly global solution to the COVID-19 pandemic,” said Dr. Seth Berkley, CEO of Gavi, the Vaccine Alliance. ““For the vast majority of countries, whether they can afford to pay for their own doses or require assistance, it means receiving a guaranteed share of doses and avoiding being pushed to the back of the queue, as we saw during the H1N1 pandemic a decade ago.  Even for those countries that are able to secure their own agreements with vaccine manufacturers, this mechanism represents, through its world-leading portfolio of vaccine candidates, a means of reducing the risks associated with individual candidates failing to show efficacy or gain licensure.”

The COVAX Facility forms a key part of the COVAX pillar (COVAX) of the Access to COVID-19 Tools (ACT) Accelerator, a ground-breaking global collaboration to accelerate the development, production, and equitable access to COVID-19 tests, treatments, and vaccines. COVAX is co-led by Gavi, the Coalition for Epidemic Preparedness Innovations (CEPI) and WHO, working in partnership with developed and developing country vaccine manufacturers. COVAX aims to accelerate the development and manufacture of COVID-19 vaccines, and to guarantee fair and equitable access for every country in the world.

It may be mentioned that CEPI is an innovative partnership between public, private, philanthropic, and civil organisations, launched at Davos in 2017, to develop vaccines to stop future epidemics. CEPI has moved with great urgency and in coordination with WHO in response to the emergence of COVID-19 and has initiated nine partnerships to develop vaccines against the novel coronavirus. Before the emergence of COVID-19, CEPI’s priority diseases included Ebola virus, Lassa virus, Middle East Respiratory Syndrome coronavirus, Nipah virus, Rift Valley Fever and Chikungunya virus.

“This early level of interest represents a tremendous vote of confidence in COVAX and our shared goal to protect people around the globe through the fair allocation of a COVID-19 vaccine,” said Dr. Richard Hatchett, CEO of CEPI. “COVAX offers an innovative solution to the gravest public health crisis in living memory. It will speed up the availability of safe and effective vaccines through early investment in manufacturing capacity, and maximise the chances of success by backing a broad and diverse portfolio of vaccine candidates. Through COVAX our aspiration is to be able to vaccinate the most vulnerable 20% of the population of every country that participates, regardless of income level, by the end of 2021. Ensuring fair access is not only a matter of equity; it is the fastest way to end this pandemic”.

Significant progress has been achieved by the COVAX partners to date, with seven of the nine candidate vaccines supported by CEPI already in clinical trials. A memorandum of understanding with AstraZeneca also commits them to supply 300 million doses of COVID-19 vaccines to COVAX.

The goal of COVAX is by the end of 2021 to deliver two billion doses of safe, effective vaccines that have passed regulatory approval and/or WHO prequalification. These vaccines will be delivered equally to all participating countries, proportional to their populations, initially prioritising healthcare workers then expanding to cover 20% of the population of participating countries. Further doses will then be made available based on country need, vulnerability and COVID-19 threat. The COVAX Facility will also maintain a buffer of doses for emergency and humanitarian use, including dealing with severe outbreaks before they spiral out of control.

“The COVID-19 pandemic, like every health crisis, also presents us with opportunities,” said Dr Soumya Swaminathan, WHO Chief Scientist. “A vaccine that is affordable and accessible to all will help us address systemic health inequalities. We need all countries to support COVAX to achieve this goal and bring an end to the acute phase of the pandemic.”

The success of these efforts will ultimately depend on securing enough funding from governments and commitments from vaccine manufacturers to participate at a scale large enough to deliver a global solution. The formal expressions of interest submitted are non-binding; the COVAX pillar will now begin a process of consultation with all 165 countries, with countries funding vaccines through their own domestic budgets being required to provide an upfront payment and a commitment to purchase doses by the end of August to secure involvement in the COVAX Facility.

In addition, in June Gavi launched the COVAX Advance Market Commitment (AMC), a financing instrument aimed at incentivising vaccine manufacturers to produce sufficient quantities of eventual COVID-19 vaccines to ensure access for developing countries. The AMC has already raised close to US$ 600 million against an initial target of US$ 2 billion from high income donors as well as the private sector.  The Gavi Alliance will also work with the developing countries to assure readiness of supply and cold chain and training to reach high risk groups.
