The availability of the Novavax COVID-19 vaccine offers another option for people who may have been hesitant about getting vaccinated. The mRNA vaccines, like Pfizer and Moderna , contain a piece of genetic code called RNA that the body creates an immune response for. It uses a different technology. Download AMA Connect app for Determining the best antigen to include in the vaccine takes time and it will take longer to change this antigen if needed, Yildirim says. Myocarditis, a rare form of inflammation of the heart muscle, occurred in a handful of Novavax clinical trial participants, all of whom were men. There's some data suggesting that certain proteins in the heart look like spike proteinsbut it doesn't look that much like a spike protein, so why certain individuals have more of a reaction than others is still not clear, says Dr. Wilson. The incidence rate of adverse events with the CoronaVac vaccine was about 0.08 per cent, or 312, of 392,122 doses administered, according to a previous HSA report in March. The background incidence of appendicitis is estimated to be about 100 per 100,000 people per year. For some people older than 12, especially boys and men between ages 12 and 39, the CDC suggests an eight-week interval between the two shots to reduce the risk of myocarditis, an uncommon side effect (see FDA warnings below).

However, we can't directly compare myocarditis rates between Novavax and mRNA vaccines based on currently available data, Dr. Fryhofer added. The CDCs study was based on COVID-19 tests performed in the pharmacy, and it found effectiveness against the XBB strains varied by age: in ages 18 to 49, it was 49% against the XBB strains versus 52% against the BA.5 viruses; in ages 50 to 64, it was 40% compared to 43% for BA.5; and in people 65 and older, 43%, compared to 37% for the BA.5 viruses.

Dosage:Single shot. To look for available vaccine appointments near you, visit Vaccines.gov. However, we can't directly compare myocarditis rates between Novavax and mRNA vaccines based on currently available data, Dr. Fryhofer added. 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. This will take much less time with mRNA vaccines since once the genomic target is identified, mRNA signature can be quickly and easily edited, and a new version of the vaccine can be manufactured. No, Novavax does not use mRNA. Anyone 12 or older can get the Novavax vaccine. Novavax says there is insufficient evidence to establish a causal relationship" between the vaccine and the condition.
