US refuses to join international effort to develop Covid-19 vaccine

The US government has said that it will not participate in a global initiative to develop, manufacture and equitably distribute a vaccine for Covid-19 because the effort is co-led by the World Health Organization. The Covid-19 Vaccines Global Access Facility (Covax) is a plan developed by the WHO, along with the Coalition for Epidemic Preparedness Innovations and Gavi, the Vaccine Alliance, and is meant to accelerate the development and testing of a vaccine and work toward distributing it equally. The WHO announced last month that more than 170 countries were in talks to participate in Covax.
