Pfizer and BioNTech’s Covid-19 vaccine is first to win full FDA approval

The Food and Drug Administration has approved Pfizer and BioNTech’s Covid-19 vaccine for people 16 and older — making it the first to be fully licensed for use in the United States.

FDA’s decision to fully approve the shot will make it easier for universities, hospitals and other workplaces to require vaccination against the coronavirus, and it is a crucial step toward enabling the Biden administration’s plan to offer booster shots for adults beginning in September. Public health experts also hope the approval will convince a significant number of vaccine holdouts to get the shot, boosting the country’s vaccination rate as it battles the highly contagious Delta variant.

“The FDA’s approval of this vaccine is a milestone as we continue to battle the COVID-19 pandemic,” acting FDA Commissioner Janet Woodcock said in a statement. “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.”

Pfizer CEO Albert Bourla also expressed hope that the full licensure would increase confidence in the shot. More than 204 million doses of the shot have been administered to people in the United States since it received emergency authorization late last year, and the vaccine is in wide use globally.

“Today’s approval for those aged 16 and over affirms the efficacy and safety profile of our vaccine at a time when it is urgently needed,” Pfizer CEO Albert Bourla said in a statement. “I am hopeful this approval will help increase confidence in our vaccine, as vaccination remains the best tool we have to help protect lives and achieve herd immunity.”

In addition to full approval for those 16 and older, the vaccine is authorized for emergency use in teens 12 to 15. Pfizer and BioNtech are studying the shot’s safety and efficacy in younger children and infants. If all goes well, they are expected to seek emergency authorization for 5-to-11-year-olds this fall.

Another vaccine maker, Moderna,is not far behind. It applied to FDA in June for full approval of its Covid-19 shot, which the agency authorized for people 18 and older late last year. The company is also seeking emergency authorization to use the vaccine in teens 12 to 17, and it is running clinical trials of its vaccine in kids as young as six months.

Johnson & Johnson, the third company with a Covid-19 shot in use in the U.S., has said it will seek full approval later this year.

The Pfizer-BioNTech shot is the first based on mRNA technology to be fully licensed by FDA for any disease. It uses snippets of mRNA, a type of genetic material, to instruct human cells to pump out harmless copies of the coronavirus’s spike protein. The body’s immune system reacts by making antibodies to the spike protein that protect against infection by the virus.

The U.S. government has purchased 500 million doses of the Pfizer vaccine for use at home, and another 500 million that it plans to donate to countries in need.

FDA earlier this month authorized third doses of the Pfizer and Moderna vaccines for people with compromised immune systems, including recipients of solid-organ transplants. The Biden administration plans to offer booster doses starting Sept. 20 to adults who received either of the two mRNA vaccines at least eight months ago. The CDC’s vaccine advisory committee is expected to meet this week to discuss the booster plan.

The initial two-dose regimen of the Pfizer-BioNtech vaccine was 95 percent effective in a late-stage clinical trial. The two companies recently released a study that showed that the vaccine’s effectiveness decreased to about 84 percent within 4-6 months after the second dose. But recent real-world studies have suggested that the standard two-shot regimen is less protective against the Delta variant than it was against earlier versions of the virus, prompting the call for boosters in the U.S. and other countries.

A Mayo Clinic study found that the effectiveness of the Pfizer-BioNTech vaccine dropped from 76 percent against prior strains of Covid-19 to 42 percent against Delta. And data collected in Israel showed the shot’s effectiveness against infection declined from about 95 percent in June to 64 percent in July as the Delta variant took over.

Does Pfizer require employees to be vaccinated?

Pfizer said on Aug 4, it will require all its U.S. employees and contractors to get vaccinated against Covid-19 or participate in regular weekly testing.

The new initiative will “best protect the health and safety of our colleagues and the communities we serve,” Pfizer spokesperson Pamela Eisele said in a statement to CNBC.

“Outside the U.S., the company is strongly encouraging all colleagues who are able to do so in their countries get vaccinated,” Eisele added. “Colleagues who have medical conditions or religious objections will be able to seek accommodations. Colleagues are still required to adhere to all COVID-19 state, local and Pfizer safety procedures while engaged in Pfizer work.”

Pfizer was the first to be authorized in the United States, is just the latest company to require its employees to get the shots.
