WHO’s expert group on immunization (SAGE) met last week to review evidence and is now recommending an additional #covid19 vaccine dose for two groups of people:
1. Anyone who is moderately or severely immunocompromised no matter which vaccine they received
1. Anyone who is moderately or severely immunocompromised no matter which vaccine they received
2. Anyone 60 or over who received two doses of the inactivated vaccines from Sinopharm or Sinovac. (The evidence this is based on comes mostly from Latin American countries, where these have been used widely)
In both cases @WHO considers the additional dose to be part of the primary immunization series, so separate from the discussion about booster shots to shore up waning immunity.
@WHO Obviously, the decision on Sinopharm and Sinovac is going to impact vaccine supply and SAGE is recommending that countries aim to maximise coverage with two doses in the older age group and only then move to administering third doses starting with oldest age groups.
@WHO The group has also prepared recommendations for use of COVAXIN, the Bharat Biotech #covid19 vaccine.
That vaccine has not been listed for Emergency Use yet by WHO, however, and so the recommendations will only come out if and when that happens.

@WHO These recommendations (plus more on polio, malaria, influenza and hepatitis E vaccines) can be found here now:
