Pfizer Inc's CEO Albert Bourla has said that the company is "not certain" if those who receive its vaccine will be able to transmit the coronavirus to others, just one day after the UK became the first to approve the inoculation. “Even though I’ve had the protection, am I still able to transmit it to other people?”, said Bourla. ''I think this is something that needs to be examined. We are not certain about that right now.'' said Albert Bourla.
