UPDATED: Unlike 1-day VRBPAC-to-EUA timeline of peers, Novavax’s Covid-19 jab awaits FDA review of recent manufacturing data
Moderna, Pfizer/BioNTech and Johnson & Johnson all received FDA clearance for their Covid-19 vaccines a day after the agency’s advisors recommended emergency authorization. The same will not happen for Novavax.
The regulator’s outside experts recommended 21 to 0 on Tuesday afternoon to give an emergency green light to the Maryland biotech’s vaccine, but more than 36 hours later, an official OK hasn’t been handed down yet. The FDA received manufacturing updates from the company just days before the advisory committee’s hours-long hearing.
“On June 3, 2022, Novavax submitted an amendment with updated manufacturing and product information for the EUA to the FDA for review,” an FDA spokesperson wrote in an emailed statement to Endpoints News. “FDA will carefully review this and any additional information submitted by the firm as part of its ongoing assessment and prior to authorizing the vaccine for emergency use. The decision to grant an EUA will also take into consideration the discussion of clinical data and voting outcome of the June 7, 2022 VRBPAC meeting.”
“The data is a part of the standard process improvements that have been made since submission and on June 3, Novavax submitted an amendment with this updated manufacturing information for the EUA to the FDA for review,” a company spokesperson said in an emailed statement to Endpoints News.
After receiving more than a billion dollars in government funding early in the pandemic, Novavax failed to keep pace with its competitors, at least on the home front. The company’s vaccine, made by the world’s largest vaccine manufacturer, the Serum Institute of India, has been given various levels of approval in more than 40 countries.

Novavax submitted its CMC data package on Dec. 31, 2021, and then applied for the EUA on Jan. 31.
The US has yet to sign off, and if the FDA does, the vaccine will still have to wait for a nod from the CDC.
Novavax, public commenters, FDA officials and some of the outside experts on Tuesday discussed the vaccine’s potential to sway those who have yet to receive an inoculation for the pandemic virus. Definitive proof of whether the traditional platform behind the vaccine, as compared to the more nascent mRNA technology in Moderna and Pfizer’s, could not be provided by the company.
When asked by an advisor whether the company had reached out to the vaccine-hesitant to see if they would take Novavax’s vaccine, CMO Filip Dubovsky replied: “One in 10 Americans hasn’t been vaccinated and we haven’t given up on them.”
