WHO calls for a temporary moratorium on administering booster shots of Covid-19 vaccines
The World Health Organization called Wednesday for a temporary moratorium on the use of Covid-19 vaccine booster shots by wealthy countries, saying the global priority should be on increasing supplies of first doses to countries that are still struggling to protect health workers and the elderly.
Director-General Tedros Adhanom Ghebreyesus said that countries should hold off on starting to give booster doses until at least the end of September — though it was quickly clear that the global health agency might extend the call if vaccine doses available to developing countries do not increase to adequate levels.
