The European Commission, which is negotiating on behalf of all 27 EU member states, said the deal included an option to purchase 100 million additional doses from the British drugmaker should its vaccine prove safe and effective.
The EU’s bilateral deal mirrors moves by the United States and other wealthy states, some of which are critical of the WHO’s initiative, and further reduces the potentially available stock in the race to secure effective Covid-19 vaccines.
The EU move could complicate efforts led by the WHO and GAVI, a global alliance for vaccines, to buy shots on behalf of rich and developing countries with a separate scheme.
The Commission has urged EU states to shun the WHO-led initiative because it sees it as too expensive and slow, EU officials told Reuters in July
