President and CEO of Pfizer, Albert Bourla, said last week that people would “probably” need a third dose of his company’s COVID-19 injection within six to 12 months of vaccination.
Speaking during the CVS Health Live event, Bourla said that the new data show that the Pfizer vaccine is effective against the worrying variant of coronavirus, which was first seen in South Africa.
“The likely scenario is that a third dose is likely to be needed, somewhere between six and 12 months, followed by an annual revaccination, but all this needs to be confirmed,” he said, adding that the variants would play a “key role”.
“It’s extremely important to suppress a set of people who may be susceptible to the virus.”
Researchers do not currently know how long vaccines provide protection against coronavirus.
The Greek CEO also defended his company’s vaccine price, saying they were saving lives and would not be sold to poor countries for profit.
“Vaccines are very expensive … They save lives, they allow economies to reopen, but we sell them at meal prices.”
