The WHO's proposed vaccine distribution framework ensures all countries access to the novel coronavirus vaccine once it becomes available. Seventy-eight wealthier countries have endorsed the program, with Germany, Japan, Norway and the European Commission this week expressing an interest in participating in the COVAX facility as self-financing countries. So far, a total of 170 nations intend to participate in COVAX, representing about 70% of the world's population. The US is not among them.
