People with weaker immune systems should receive an additional shot of approved COVID-19 vaccines, an advisory group to the World Health Organization (WHO) said on Monday.
The recommendation follows a four-day meeting of the Strategic Advisory Group of Experts (SAGE) on Immunization. A final report will be issued in December.
SAGE said moderately and severely immunocompromised persons should be offered an additional dose of all WHO-approved vaccines “since these individuals are less likely to respond adequately to vaccination following a standard primary vaccine series and are at high risk of severe COVID-19 disease.”
People aged 60
and older who received the Sinovac and Sinopharm vaccines should get a third
dose too, the experts added, though use of other vaccines may also be
considered depending on supply and access.
WHO last week announced a plan to end the COVID-19 pandemic by ensuring all people, everywhere, have access to vaccines.
