The U.S. drug regulator on Monday (August 23) granted full approval to the Pfizer Inc (PFE.N)/BioNTech SE COVID-19 vaccine that had earned emergency-use authorization in December, making it the first to secure such Food and Drug Administration validation as health authorities struggle to win over vaccine skeptics.
The FDA approved the two-dose vaccine for use in people age 16 and older. Public health officials hope the action will convince more unvaccinated Americans that Pfizer’s shot is safe and effective. Vaccine hesitancy among some Americans has hindered the U.S. response to the COVID-19 pandemic.
“While millions of people have already safely received COVID-19 vaccines, we recognize that for some, the FDA approval of a vaccine may now instill additional confidence to get vaccinated,” said Janet Woodcock, the FDA’s acting commissioner.
U.S. health officials also expect that the full approval will prompt more state and local governments, as well as private employers, to employ vaccine mandates.
Pfizer shares were up around 5% and BioNTech shares were up more than 9%.
The FDA gave emergency use authorization to the vaccine for people age 16 and older in December – making it the first shot to gain such backing – and then later gave further emergency use authorization for people age 12 and up in May. The new authorization does not give final approval for those between ages 12 and 15.
None of the three COVID-19 vaccines given emergency-use authorization by the FDA – also including those made by Moderna Inc (MRNA.O) and Johnson & Johnson (JNJ.N) – had previously received full FDA approval.
More than 204 million people in the United States have received the Pfizer/BioNTech vaccine since it was given emergency authorization, based on data from Sunday.
Vaccine skepticism runs deep among some Americans, particularly conservatives. COVID-19 cases, driven by the highly infectious Delta variant, have surged in places with lower levels of vaccination.
According to the U.S. Centers for Disease Control and Prevention, 71% of Americans age 12 and older- the population eligible to receive COVID-19 vaccines – have received at last one dose and 60.2% are fully vaccinated. For the entire population, including children up to age 11 for whom no vaccines are yet approved, 60.7% of Americans have received at least one dose and 51.5% of them are fully vaccinated.
The FDA’s approval is based on updated data from the company’s clinical trial. Overall, in follow-ups to Pfizer’s original late stage study, approximately 12,000 recipients of the vaccine have been followed for at least six months.
Last week, the U.S. government announced plans to distribute 100 million booster shots, targeting all Americans who received their first inoculation more than eight months earlier
