The pharma giant’s CEO also revealed that people getting re-vaccinated annually against the virus is a “likely scenario”.
People will “likely” need a third dose of a Covid-19 vaccine within a year of being fully vaccinated, according to Pfizer CEO Albert Bourla.
Speaking to CNBC, the head of the pharma company also stated that people may require vaccination against the virus every year.
He said: “A likely scenario is that there will be likely a need for a third dose, somewhere between six and 12 months and then from there, there will be an annual re-vaccination.”
However, he added that this has not been confirmed as of yet and that variants of the virus will play “a key role” in the administration of future booster doses.
At the beginning of April, Pfizer said studies had shown that their vaccine was 91.3% effective in protecting against Covid-19 and 95.3% effective at preventing severe Covid-19 up to six months following a second dose.
However, it is not fully known how long protection from Covid-19 vaccines lasts for after this point.
Earlier this week, it was announced that Ireland is set to receive 550,000 more Pfizer vaccine doses over the next three months than had originally been expected.
The producer has reached a deal with the European Commission which will see countries in the European Union receive 50 million more Covid-19 vaccines in the second quarter, the head of the EU commission said on Wednesday.
Ursula von der Leyen said the deliveries will likely start this month and will take total supplies to the EU from Pfizer to 250 million doses in the second quarter of this year.
