New Delhi: At a press briefing on 21 January, the UN health agency said it was now recommending booster doses of the Pfizer-BioNTech vaccine, beginning in the highest-priority groups, about four to six months after receiving the first two doses, in line with guidance from dozens of countries that embarked upon booster programs months ago.
Last year, WHO pleaded with rich countries to declare a moratorium on offering booster doses until the end of 2021, an appeal that went almost entirely ignored. The agency said its expert vaccine group assessed the increasing data about booster doses and noted the waning of immune protection over time.

Numerous studies have shown in recent months that booster doses restore antibody levels and offer strong protection against severe disease, including against COVID-19 variants like delta and omicron.
Boosters are part of the vaccination program, but it doesn't mean unfettered use to all ages, said WHO's Dr Kate O'Brien, director of immunisation, vaccines and biologicals. We continue to have the highest focus on vaccination of the highest priority groups, she said.
