A senior Pfizer executive has admitted that the drug company did not know whether its Covid vaccine prevented transmission of the virus when it began rolling out the shots globally.
Janine Small, Pfizer’s president of international developed markets, was testifying before the European Union Parliament on Monday when she was asked the question by Dutch MEP Rob Roos.
— appearing in the place of Pfizer chief executive Albert Bourla, who had been called to testify but pulled out of the hearing earlier this month — replied that the company had to “move at the speed of science”.
