PFIZER’S boss has said he thinks people may need a third dose of the Covid-19 vaccine.
Albert Bourla, 59, said a potential booster shot would be administered six to 12 months after someone had been fully vaccinated.
“There are vaccines that are like polio that one dose is enough…and there are vaccines like flu than you need every year,” he said.
“The Covid virus looks more like the influenza virus than the polio virus.”
His comments come as fears rise for new variants after 77 cases of the Indian strain were detected in the UK.
Seventy-three cases are in England and four are in Wales.
And a new study showed the risk of a brain blood clot after the AstraZeneca vaccine was five in a million, and four in a million after vaccines from Pfizer or Moderna.
For people who had Covid, the risk was almost 40 in a million.
Researchers at Oxford – the same university that created the AstraZeneca vaccine – said either after the coronavirus or a jab, the risk of a brain blood clot in the following two weeks was very rare.
But comparing the two, they said the risk was “substantially and significantly higher” after Covid – which is largely avoidable with a vaccine.
