WHO-Interim Statement on COVID-19 vaccines

Yesterday WHO issued this interim statement. They are pushing for more vaccine for initial shot than for boosters.

Global public health goals of COVID-19 vaccines
In practical terms, while some countries may recommend booster doses of vaccine, the immediate priority for the world is accelerating access to the primary vaccination, particularly for groups at greater risk of developing severe disease.[3]

*With near- and medium-term supply of the available vaccines, the need for equity in access to vaccines across countries to achieve global public health goals, programmatic considerations including vaccine demand, and evolution of the virus,*a vaccination strategy based on repeated booster doses of the original vaccine composition is unlikely to be appropriate or sustainable.
