The world’s wealthiest countries have already signed contracts to buy more than 1.3 billion doses of coronavirus vaccines, reports, citing Bloomberg.

According to Airfinity analysts, the United States, Great Britain, Japan, and the European Union countries intend to buy another 1.5 billion vaccines due to unopened supplies and deals.

Experts fear that this “aggressive procurement” will put other countries in a bad position.

The US and the United Kingdom have signed agreements with Sanofi and GlaxoSmithKline Plc, while Japan has signed agreements with Pfizer.
