FDA advisers support Novavax's Covid-19 vaccine for authorization & More News Here

“This is a different technology. It’s a more traditional protein-based vaccine,” Portnoy stated. “The vaccine deserves the opportunity to be given and studied.”

“Certainly, the benefits outweigh the risks for a primary series,” committee member Dr. Michael Nelson, bronchial asthma, allergy and scientific immunology division chief on the University of Virginia School of Medicine, stated of the vote.

“I think this group was in full recognition that this is probably a three-dose series and then will need to accumulate data supporting the need for booster doses and subsequent doses to probably make it a three-dose vaccine,” he stated, hinting at how discussions would possibly proceed for the vaccine for use as a booster shot.

The instances have been just like myocarditis after the mRNA Covid-19 vaccines developed by Pfizer/BioNTech and Moderna, they usually elevate “concern for a causal relationship” with Novavax’s vaccine, in accordance with the FDA doc.

Novavax seeks US authorization

In November, Indonesia turned the primary nation to grant emergency use authorization of Novavax’s vaccine. It has additionally been approved within the European Union, the United Kingdom, Canada, South Korea, Australia, India, the Philippines and New Zealand, amongst different nations.

Novavax is ready to ship doses of its vaccine from the Serum Institute in India when the FDA authorizes it.

“Our hope is that the FDA takes the recommendation of this VRBPAC committee … along with all the manufacturing data that we’ve given them and with the results of their inspection of our plant in India, and can reach a decision. We hope that’s soon,” Stanley Erck, Novavax’s president and chief govt officer, informed CNN on Tuesday.

The firm’s first cargo to the United States can be “a few million” doses, he stated.

As for who may obtain the vaccine, “there are tens of millions of people who have not had their primary vaccine for one reason or another,” Erck stated. “That’s one market for us.”

He added that different markets for the vaccine embody kids and, finally, individuals who want booster doses to take care of safety towards Covid-19.

Novavax’s request for authorization was based mostly on information together with the outcomes of two giant scientific trials that demonstrated an general efficacy of about 90% and a “reassuring safety profile,” in accordance with the corporate. The trials have been performed earlier than the Omicron coronavirus variant dominated within the United States.

“The Advisory Committee’s positive recommendation acknowledges the strength of our data and the importance of a protein-based COVID-19 vaccine developed using an innovative approach to traditional vaccine technology,” Erck stated in an announcement after Tuesday’s assembly.

“We have heard in today’s VRBPAC meeting the significant support for our vaccine from physicians, healthcare organizations, and consumers who are eagerly anticipating a protein-based vaccine option,” he stated. “We look forward to the FDA decision.”

Overall, the uptake of Covid-19 vaccinations — particularly booster doses — within the United States has been sluggish, and one FDA official described it as a “very serious” downside in Tuesday’s assembly.

“We do have a problem with vaccine uptake that is very serious in the United States, and anything we can do to get people more comfortable to be able to accept these potentially life-saving medical products is something that we feel we are compelled to do,” stated Dr. Peter Marks, director of the Center for Biologics Evaluation and Research.

Dr. Eric Rubin, editor-in-chief of the New England Journal of Medicine and a member of VRBPAC, requested within the assembly why there’s a want for one other Covid-19 vaccine within the United States when three have been approved or accepted: these from Pfizer/BioNTech, Moderna and Johnson & Johnson’s Janssen.

“The Janssen vaccine is currently not being used as a frontline vaccine the same way as the mRNA vaccines, which leaves the issue of vaccines for those who might not want to take an mRNA vaccine because of concerns they might have,” Marks responded, referring to the vaccines developed by Pfizer/BioNTech and Moderna.

“Having a protein-based alternative may be more comfortable for some in terms of their acceptance of vaccine,” Marks stated.

Protein-based vaccines like Novavax’s work by getting the physique’s immune system to acknowledge little modified items of the virus it is concentrating on. In this case, meaning items of the coronavirus spike protein.

Novavax scientists recognized the gene for the spike protein and created a modified model of that gene. The researchers cloned the genes right into a baculovirus that infects bugs. They then contaminated moth cells — particularly, cells from the autumn armyworm — prompting them to provide the coronavirus spike protein. These virus-like nanoparticles have been harvested to make Novavax’s vaccine.

Overall, the vaccine depends on recombinant nanoparticle know-how and Novavax’s adjuvant, referred to as Matrix-M, to stimulate an immune response and excessive ranges of neutralizing antibodies.

“It’s not infectious. We never touch the coronavirus itself,” Glenn added. “Then that is given to people, and they make an immune response that’s very much focused just on the spike — and I would say, the hallmark of our vaccine is, it gives a very strong immune response with very few side effects, and the dose is very small and the vaccine can be stored with normal refrigerated temperatures.”
