There is a huge experience behind this technology, Yildirim says. In November 2022, Pfizer announced that a clinical trial showed levels of neutralizing antibodies in the bivalent booster were fourfold higher in people 55 and older than in people of similar ages who got a monovalent booster, which targeted only the original virus. The company also announced that it started a study in May looking at Novavax boosters after an mRNA primary vaccine series, Dr. Fryhofer explained. The main difference between the Novavax vaccine and the already-approved and widely used vaccines from Pfizer/BioNTech and Moderna is the technology behind the shots. Not as quick. It uses the spike proteins themselves, in the form of nanoparticles, to trigger an immune response. "The mRNA platform is far more modifiable than what Novavax does," he said. A two-dose series of Novavax protein subunit COVID vaccine is now recommended for unvaccinated individuals who are 12 or older for primary vaccination against COVID-19., But it is important to note that Novavax has to be used for both doses in the primary series, she said. How does it stack up to Moderna and Pfizer's mRNA vaccines? All four were not serious and had reported experiencing rash, chest pain, dizziness, and vasculitis (blood vessel inflammation). in people who had previously received two to four monovalent vaccine doses, and found it to be similar to how well it worked against BA.5 for at least the first three months after vaccination.

But Novavax has submitted booster data to the FDA. FDA warnings: The FDA added a warning label on the mRNA vaccines regarding serious (but rare) cases of inflammation of the heart muscle (myocarditis) and of the outer lining of the heart (pericarditis) in adolescents and young adults, more often occurring after the second dose of an mRNA vaccine. Both Pfizers and Modernas vaccines use messenger RNA (mRNA) to deliver a blueprint of sorts to cells in the body. Bivalent booster shots authorized in August 2022 are designed to protect against disease caused by the original strain of the SARS-CoV-2 virus, as well as Omicron variants BA.4 and BA.5.

It remains to be seen whether this report of fewer side effects holds up in a real-world setting. Even though Pfizer-BioNTech and Moderna mRNA vaccines are safe and highly effective, weve heard a lot of people say the reason they've chosen not to get an mRNA vaccine is because the mRNA technology is relatively new and it hasn't been tried on a wide scale before., There are practical reasons as well.
