The Motley Fool recommends Moderna Inc. Its important to note that, for both age groups, the data on the vaccines efficacy was gathered before Omicron became the predominant variant, so its efficacy against Omicron and its subvariants is unknown. Alternatively, adults are eligible for a Pfizer-BioNTech or Moderna bivalent booster at least two months after their primary Novavax vaccination, and teenagers ages 12 through 17 must get a Pfizer-BioNTech bivalent booster. Subunit vaccines are reliable and familiarthey have been around for many years. (It injects a version of the spike protein that has been formulated in a laboratory as a nanoparticulate that does not have genetic material inside and cannot cause disease.). Subunit vaccines are expected to trigger only antibody-mediated immune responses, Yildirim says. Novavax's vaccine uses a traditional mechanism as compared to mRNA vaccines. How it works: Unlike the mRNA and vector vaccines, this is a protein adjuvant (an adjuvant is an ingredient used to strengthen the immune response). A small rise in incidents of appendicitis two additional cases per 100,000 administered doses were observed occurring within 21 days after the primary vaccination series of the Pfizer vaccine, mainly in those aged 12 to 17.

That's another similarity with Moderna and Pfizer. How it works: It uses mRNA technology, which is a new type of vaccine. When the vaccine is injected, this stimulates the immune system to produce antibodies and T-cell immune responses. Both Pfizers and Modernas vaccines use messenger RNA (mRNA) to deliver a blueprint of sorts to cells in the body. Novavax is not available for boosters yet. Nick Blackmer is a librarian, fact-checker, and researcher with more than 20 years experience in consumer-oriented health and wellness content.

Whereas Novavax is going be simpler. It uses a different technology. 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. The Novavax COVID-19 vaccine was recently granted emergency use approval by the FDA. It says vaccine recipients should seek medical attention right away if they experience any of the following symptoms: chest pain, shortness of breath, and/or feelings of having a fast-beating, fluttering, or pounding heart. No dilutions necessary, but vaccine has to be discarded if it's not used within six hours after the first puncture of the vial., In the study, vaccine doses were administered three weeks apart. 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. How well it works: 90% effective overall against lab-confirmed, symptomatic infection and 100% effective against moderate and severe disease in Phase 3 trial results published in The New England Journal of Medicine in December 2021. The Pfizer-BioNTech and Moderna COVID-19 vaccines use a newer mechanism in which messenger RNA is used to lead cells to create a protein on the virus surface that the immune system Teenagers ages 12 through 17 who had the Novavax primary series must get a Pfizer-BioNTech bivalent booster. However, there's a lot of interest in the prospect of using Novavax as a booster, especially since mRNA vaccines don't seem to be that durable..

Lower rates of vaccine side effects are important, in particular for adults who are concerned about lost wages or unscheduled time away from work, Tanjala Purnell, PhD, assistant professor of epidemiology at the Johns Hopkins Bloomberg School of Public Health, tells Verywell. However, we can't directly compare myocarditis rates between Novavax and mRNA vaccines based on currently available data, Dr. Fryhofer added. For example, an adult who is employed in an hourly-wage job may have less schedule flexibility and less job security than a person who is employed in a salaried position, Purnell says. You store it at regular refrigerator temperatures but don't freeze it. It comes in 10-dose vials, and it's preservative free. Fully effective two weeks after vaccination.
