Pfizer – 3rd vaccine dose likely needed in 12 months
Pfizer CEO Albert Bourla said people will ‘likely’ need a third dose of a Covid-19 vaccine within 12 months of getting fully vaccinated.
Researchers still don’t know how long protection against the virus lasts once someone has been fully vaccinated. Pfizer published a study earlier this month that said its jab is more than 91 percent effective at protecting against the coronavirus, and more than 95 percent effective against severe cases of Covid-19 up to six months after the second dose.
Bourla also reported during the panel that the company began testing in February whether a third shot could offer better protection against new strains of the virus such as the one first found in South Africa.
The Pfizer vaccine, developed in partnership with German firm BioNTech, currently plays a leading role in American and European vaccination campaigns.
