Real-world data show that the Pfizer vaccine is effective against a worrying variant of the coronavirus first seen in South Africa, called B.1.351, Bourla said during a CVS Health Live event posted on Facebook on Thursday. “Protection decreases with time, but in six months it is still extremely high,” he said.
“If you ask me, I think revaccination will be needed based on this data,” Bourla added.
Bourla said it remains to be seen how often this should happen, but “a likely scenario is that there will probably be a need for a third dose somewhere between six and 12 months and then from there, there will be a re-vaccination. . But all this must be confirmed. “
“In pandemics, you are as protected as your neighbor,” Bourla said. He said that was why it was important for all countries to vaccinate their citizens.
