Pfizer Studying Effects Of Third Vaccine Dose

PFIZER is studying the effects of a third vaccine dose to target more resistant virus strains

Pharmaceutical giant Pfizer reported on Thursday, February 25 that it is studying the effects of administering a third dose of the vaccine in order to tackle the more transmissible mutant strains of coronavirus. While the company has repeatedly insisted that its jab is just as effective against the current variants, such as the South African and British strains, representatives said they are experimenting in case the virus mutates further in the future.

In order to ascertain if a third booster shot of the jab administered between six and twelve months after the first two doses boosts the immune system enough to counteract mutations, Pfizer is currently administering the shot to 114 volunteers in the US who participated in their earlier trials.

“While we have not seen any evidence that the circulating variants result in a loss of protection provided by our vaccine, we are taking multiple steps to act decisively and be ready in case a strain becomes resistant to the protection afforded by the vaccine,” Albert Bourla, Pfizer’s Chief Executive Officer, said in a statement.

“There is a possibility there some day will be a variant that really does escape protection, so we are making preparations,” Philip Dormitzer, Pfizer’s chief scientific officer for viral vaccines added.
