Moderna booster side effects9/15/2023 ![]() What side effects should I expect?ĪusVaxSafety, Australia’s national active vaccine safety surveillance system, found Australians who’ve already had their booster vaccine reported similar side effects as they did after their second dose, for both Pfizer and Moderna boosters. Despite encouraging evidence from clinical trials, it’s not currently approved as a booster.īoosters aren’t yet recommended in younger adolescents (less than 16 years old) and children. Novavax, the new protein-based COVID vaccine, is currently only approved for use in the first two doses. Pfizer’s is a full dose just like the first two, while Moderna’s booster dose is half the dose of the primary vaccine.ĪstraZeneca has been approved as a booster dose, but Pfizer and Moderna remain preferred, except in a small number people who have had a significant adverse reaction to mRNA vaccines. Which booster can I have?Īustralians over 16 can now have Pfizer or Moderna as a booster, regardless of which vaccines you had for the first two. Having a booster three months following the primary course can provide similar levels of protection against Omicron as the two primary doses did for Delta. ![]() There’s now clear evidence getting your booster shot is the best way to restore protection against infection and severe disease. Omicron infections continue to cause significant impact in all Australian states and territories, with more than 2,400 Australians currently hospitalised. The protection provided by two doses of a COVID vaccine is reduced and more rapidly wanes against Omicron.ĭespite this, many eligible Australians aren’t coming forward for their booster, perhaps reassured by reports that Omicron is milder, so therefore not something to be worried about. There’s still widespread community transmission of the Omicron variant across Australia and the world. ![]() ![]() Here we answer some of your COVID booster vaccine questions. Many people are wondering how booster side effects compare to the first two doses, when they can get a booster dose after COVID infection, and whether we’ll need more than three doses in the future. You now need a third dose to be considered “up to date” with COVID vaccination, previously known as “fully vaccinated”.ĭespite this, only about half of the eligible population has received a booster dose. The Australian Technical Advisory Group on Immunisation (ATAGI) recommends Australians aged 16 years and older have a COVID booster vaccine three months after receiving their second dose.
