It helps your body create an immune response. Scientists make this in lab-grown insect cells. The Novavax vaccine is different from the other three available COVID-19 vaccines. You’ll get your second shot 3 weeks after your first. The CDC suggests Novavax if you prefer to get a vaccine that’s built on different technology than previous COVID-19 vaccines. It uses protein subunits, just like the hepatitis B, influenza, and whooping cough vaccines. The Novavax shot is like other vaccines that have been used in the U.S. This vaccine offers another option for those who haven’t gotten the Pfizer, Moderna, or J&J vaccine. Experts continue to study the vaccine for children as young as 12. The FDA has approved the emergency use of the Novavax COVID-19 vaccine for people 18 years and older. Even if you got more than one original (monovalent) booster, you should get an updated (bivalent) booster. Your final primary series dose, or an original (monovalent) booster. If you got the J&J vaccine, the CDC recommends that if you are age 5 years or older, that you receive one updated (bivalent) booster as long as it has been at least 2 months since your last COVID-19 vaccine dose, whether that was: Receiving any COVID-19 vaccine is better than being unvaccinated, experts say. ![]() That said, if you can’t get an mRNA vaccine or you don’t want to, you should get the J&J vaccine. Their recommendation is endorsed by the CDC and comes from the Advisory Committee on Immunization Practices, which reviewed the latest evidence on the effectiveness, safety, and rare side effects of available vaccines. Top health experts recommend you choose a COVID vaccine made with mRNA (like the ones from Pfizer and Moderna) rather than the J&J vaccine, which is made differently. It’s been combined with genes from the new coronavirus’s spike protein to trigger your immune system to fight it. Johnson & Johnson’s COVID vaccine has a weakened version of the adenovirus, one of the viruses that causes the common cold. The J&J vaccine uses DNA that’s designed to trigger an immune response to the virus. The updated (bivalent) Moderna booster can be given to anyone ages 6 years or older at least 2 months after 2nd primary series dose or last booster. This is an mRNA vaccine given in two doses, 4 to 8 weeks apart to people ages 6 months and older. People ages 6 years and up can get either a Pfizer-BioNTech or Moderna booster. The Pfizer-BioNTech updated (bivalent) booster can be given at least 2 months after the 2nd dose of the primary series or last booster to anyone 5 years old or older. The CDC recommends the updated (bivalent)COVID-19 booster for everyone 5 years of age or older. Children from 6 months to 4 years old get a three-dose primary series, and everyone age 5 and older gets a two-dose primary series. The children’s dose is not as strong as the adult version. This vaccine is approved for children and adults. The mRNA vaccine tells your immune cells to make just the protein and act as if they’ve already been infected with the coronavirus, giving you some immunity against it. This is what carries instructions for making the “spike” protein that lets the virus enter human cells. There are four types of vaccines approved in the United States: Anyone who had a severe allergic reaction after receiving the Johnson & Johnson or the Novavax vaccines should not get a dose of that particular one. The CDC advises that anyone who had a severe allergic reaction after getting Pfizer-BioNTech or Moderna vaccines should not get another dose of either. There have been reports of adverse allergic reactions to some of the vaccines, but these are extremely rare. The CDC says the vaccines are safe for pregnant people, and there’s no indication they pose any danger to a fetus. And everyone 5 years and older should also get a COVID-19 booster, if eligible. The CDC recommends everyone ages 6 months and older get vaccinated against COVID-19. But after the success of mass production and distribution, the vaccines were made available to a broader population. ![]() ![]() Health care workers and the elderly were the first to receive the vaccine. A vaccine is vital to helping control it. Normally, developing a vaccine for a new virus takes years, but scientists were able to get a boost from research on similar coronaviruses that cause severe acute respiratory syndrome (SARS) and Middle East respiratory syndrome (MERS).Įxperts say this coronavirus could eventually turn out to be seasonal, like colds and the flu. The virus that causes COVID-19 only surfaced in late 2019. As the coronavirus continues to cause illness and death around the world, vaccines are seen as one of the best ways to stop it.
