Albert Bourla, the chairman of Pfizer, has said that it is not certain if people who have been vaccinated by the Pfizer-BioNTech coronavirus vaccine will still be able to spread the virus to others or not. More studies are needed to ascertain this, he said in an interview on NBC’s ‘Dateline’ show.

Host Lester Holt asked if he would transmit the disease to other people even if he had the protection of the vaccine, to which Bourla replied: “I think this is something that needs to be examined. We are not certain about that right now with what we know.”

Pfizer has claimed that its vaccine candidate is 95 per cent effective. The UK was the first the country to approve the Pfizer-BioNTech vaccine for emergency use, followed by Bahrain. Researches not associated with Pfizer’s vaccine development said the company’s trials did not assess how the vaccine affects transmission.


Pfizer has applied for emergency authorisation use for its vaccine in the US, too. The US said it will evaluate the vaccine on December 10.

It said it is committed to ensuring everyone has access to the vaccine, and is working closely with governments towards this.

“During this pandemic phase, Pfizer will supply this vaccine only through government contracts based on agreements with respective government authorities and following regulatory authorisation or approval,” the statement said.
