Pfizer CEO Albert Bourla has said that vaccinated individuals will “likely” need a booster shot of the vaccine within 12 months of receiving the second dose.
His comments on the subject, which were released on Thursday, were previously recorded on 1 April.
“A likely scenario is there will be likely a need for a third dose somewhere between six and 12 months and then from there, there would be an annual revaccination,” he said.
This annual vaccination could look similar to the flu vaccine people receive each year.
“There are vaccines that are like polio that one dose is enough … and there are vaccines like the flu that you need every year,” Mr Bourla said. “The Covid virus looks more like the influenza virus than the polio virus.”
