Of the 11,168,800 Pfizer doses administered, 14,236 cases reported adverse reactions, at a 0.13 per cent incidence rate, 841 of which were serious. With the mRNA vaccines, the inflammation, in most cases, gets better on its own without treatment.

Here are some things you should know about the Novavax vaccine. Possible side effects: Injection site tenderness, fatigue, headache, muscle pain. Later data on real-world effectiveness for adults showed that the protection from the mRNA two-dose primary series wanes over time, but booster doses bring the immune system back to robust levels.

This technology has been around for more than 30 years, she said, noting its already been used in making other vaccines, for example, for flu, hepatitis B and whooping cough., Novavax can only be used as a primary series because the Food and Drug Administration (FDA) has not authorized it as a booster yet, said Dr. Fryhofer. Novavax's vaccine uses a traditional mechanism as compared to mRNA vaccines. Post-authorization safety monitoring will continue and will be so important in further defining myocarditis risk, Dr. Fryhofer noted.

After vaccination, your muscle cells begin making the S protein pieces and displaying them on cell surfaces. Vaccine side effects can be an important factor affecting whether people get the jab. How well it works against variants: At the end of 2021, J&J announced that preliminary study results from South Africa showed a J&J booster to be 85% effective against hospitalization at a time when Omicron was the dominant variant in that country.

Approving additional COVID-19 vaccines in the U.S. still has the potential to benefit the public. While other vaccines trick the bodys cells into creating parts of the virus that can trigger the immune system, the Novavax vaccine takes a different approach. It contains the spike protein of the coronavirus itself, but formulated as a nanoparticle, which cannot cause disease. Novavax was developed using protein-based, subunit technology. If you are immunocompromised:Children and teenagers ages 5 to 17 should receive three Pfizer-BioNTech primary doses, including a second dose three weeks after the first, and a third dose four weeks later. FDA warnings:The FDA placed awarning labelon the Moderna vaccine regarding a likely association with reported cases of heart inflammation in young adults.
