Biden chief medical adviser says guidance may change in future as Pfizer suggests booster may be beneficial' after six months

Dr Anthony Fauci has said there is no immediate need for a Covid-19 booster for fully vaccinated Americans but remained open to the possibility in the future, as reports suggest that one major pharmaceutical company plans to lobby government officials to approve booster shots next week.

Pharmaceutical company Pfizer announced last week that it had observed that its vaccine, while effective against the virus, had a decline in efficacy against symptomatic disease over time". The company suggested that as new variants continue to emerge a booster shot after six months may be beneficial".
