Despite the fact that a safe and effective Covid19 vaccine is at best several months away, governments across the world have been committing serious money to securing future stocks. Each country will decide who will be offered a successful vaccine first, but 80 or more countries have signed up to Covax, a scheme which aims to make vaccine available to all countries and which is led by Gavi and the Gates Foundation. Several of the pharma companies involved have said they will distribute their vaccine at cost.
The Covax protocol says that no one country can vaccinate more than 20 pct of its population at the expense of other countries in need.
The WHO blueprint for vaccination priority within a given country is 1. Health and care workers, 2. Over 65s and at risk people, 3. Others.
