Many countries are rolling out COVID-19 vaccine booster shots, but there is no consensus among scientists that they are necessary, and the world health organization wants the most vulnerable people worldwide to be fully vaccinated first.
North America – the US Centers for Disease Control and Prevention (CDC) on September 24 backed a booster shot of the Pfizer and BioNtech vaccine for Americans aged 65 and older, some adults with underlying medical conditions and some adults in high-risk working and institutional settings. Canada’s National Advisory Committee on Immunization is recommending booster shots of an authorized MRNA vaccine to those who are moderately or severely immunocompromised.
Europe – the European Union’s drug regulator recommended on October 4 a third dose of Pfizer-BioNtech and Moderna MRNA vaccines for those with a severely weakened immune system, but left it to member states to decide whether the wider population should get a booster.
