Pfizer and its partner BioNTech announced that they have begun filing for full approval of their Covid vaccine for people aged 16 and over in the United States. This makes the companies the first in the nation to apply for full regulatory approval.
The Food and Drug Administration issued emergency approval for their Covid vaccine at the end of December. Since then, Pfizer has distributed 170 million doses in the US, with the goal of having 300 million doses by the end of July.
“We are proud of the tremendous progress we have made in working with the US government to deliver vaccines to millions of Americans since December,” said Albert Bourla, Pfizer CEO, in a statement. “We look forward to working with the FDA to complete this ongoing filing and support its review with the aim of ensuring full regulatory approval for the vaccine in the months ahead.”
Pfizer’s shares fell nearly 1% in premarket trading on Friday, while BioNTech’s shares fell more than 1%. Covid vaccine manufacturers’ stocks fell after the Biden government announced earlier this week that it would waive patent protection for Covid vaccines, citing the global health crisis.
Pfizer needs to demonstrate that it can reliably manufacture the vaccines in order to get full clearance. If approved, companies could market their shots directly to consumers and potentially change the pricing of the cans. It also allows the shot to stay in the market once the pandemic is over and the US is no longer considered an “emergency”.
It usually takes the FDA about a year or more to determine whether a drug is safe and effective for the general public. Due to the once in a century pandemic that killed nearly 600,000 people in the United States, the FDA allowed the gunshots to be used as part of an emergency clearance.
The permit grants conditional approval based on data for two months. It’s not the same as a biological license application that requires six months of data and ensures full approval. Companies apply for approval on a “rolling filing” basis, which speeds the review process by allowing the FDA to review new data as soon as the company receives it.
Rival Moderna said Thursday it plans to initiate ongoing filing with the FDA for its vaccine this month.
“The BLA filing is an important cornerstone to achieving long-term herd immunity and containing COVID-19 in the future,” said Dr. Ugur Sahin, CEO and co-founder of BioNTech in Germany, in a statement. “We are excited to be working with US regulators to apply for approval of our COVID-19 vaccine based on our key Phase 3 study and follow-up data.”
Early data from 12,000 vaccinated people aged 16 and over in this phase three study showed the shots were 91.3% effective at getting the disease up for up to six months after the second dose and 95.3% effective against severe Covid as defined by the FDA companies said April 1. The data also showed “a favorable safety and tolerability profile,” they said at the time.
Dr. White House chief medical officer Anthony Fauci told CNN on April 28 that US regulators would act “as soon as possible” once companies submit their requests for full approval.
“When you get formal approval, you have to have some amount of time to do mostly safety observations, and obviously safety looks really, really good in well over 140 million people who have been vaccinated with at least a single dose.” he told CNN. “I hope you make it quick because … people who hear it is still an emergency still have a little concern about how far you can go with it.”
The companies are awaiting FDA emergency approval to use their vaccine in children ages 12-15 and intend to apply for a full license once they have six months of data.
They said in late March that the vaccine was 100% effective in a clinical study involving more than 2,000 adolescents. They also said the vaccine produced a “robust” antibody response in the children that outperformed that in a previous study in older teenagers and young adults. The side effects were generally consistent with those seen in adults, they added.
