Pfizer chairman Albert Bourla told Dateline host Lester Holt that the pharmaceutical company was “not certain” if the vaccine prevented the coronavirus from being transmitted, saying, “This is something that needs to be examined.”
In a prime-time special titled “Race for a Vaccine” set to air Thursday, Holt questioned Bourla and other individuals involved in the development and distribution of the medicine.
In November, Pfizer announced that its vaccine candidate had been shown to be more than 90 percent effective at preventing COVID-19 and has applied for emergency use authorization from the Food and Drug Administration (FDA).
