![]() ![]() ![]() The monovalent COVID-19 vaccines that are authorized or approved by the FDA and have been administered to millions of people in the United States since December 2020 contain a component from the original strain of SARS-CoV-2. The Pfizer-BioNTech COVID-19 Vaccine, Bivalent, is authorized for use as a single booster dose in individuals 12 years of age and older. The Moderna COVID-19 Vaccine, Bivalent, is authorized for use as a single booster dose in individuals 18 years of age and older. The bivalent vaccines, which we will also refer to as “updated boosters,” contain two messenger RNA (mRNA) components of SARS-CoV-2 virus, one of the original strain of SARS-CoV-2 and the other one in common between the BA.4 and BA.5 lineages of the omicron variant of SARS-CoV-2. Food and Drug Administration amended the emergency use authorizations (EUAs) of the Moderna COVID-19 Vaccine and the Pfizer-BioNTech COVID-19 Vaccine to authorize bivalent formulations of the vaccines for use as a single booster dose at least two months following primary or booster vaccination. Here's what to know based on each vaccine brand.Today, the U.S. And early data suggested that most people who received boosters had about the same side effects as they did after their second dose. The most common side effects are similar for all three types of COVID-19 vaccine boosters available in the U.S. Common COVID-19 booster shot side effects "If you're weighing the side effects of the vaccine versus the effects of COVID, I would take the side effects of the vaccine any day," Milstone said. Remember, though, that the side effects from the vaccine and the booster, while unpleasant, are typically mild and temporary. She also experienced a fever, body aches, chills and "complete exhaustion." "I'm pretty sensitive and I have a pretty low pain tolerance," she told TODAY, so dealing with the soreness after having one shot in each arm was a challenge. That's what happened to Lindsay Mann, who received her Moderna booster alongside her flu shot last month. But if you do experience side effects later, it will be difficult to know which vaccine is responsible. That's completely safe and a convenient way to cross both shots off your to-do list in the same appointment, according to the Centers for Disease Control and Prevention. Making matters even more confusing is the fact that some people may get their flu vaccine at the same time as the booster. ( Mixing and matching could make it even more challenging to predict which side effects you'll experience.) Aaron Milstone, associate hospital epidemiologist at the Johns Hopkins Hospital and pediatric infectious disease specialist at the Johns Hopkins Children's Center, told TODAY. They may be more or less severe than the ones you experienced previously, Dr. The side effects you experience after your booster dose may be different than what you felt after your first dose(s). An especially sore arm might make it difficult to work out or cook breakfast, for instance, and chills may leave you tossing and turning for a night. But, for some people, those symptoms can be so intense they have trouble doing their usual tasks. All adults are now eligible for COVID-19 booster shots, which means more people than ever have already or will soon be experiencing side effects from their boosters.Īs with the original vaccine doses, most COVID-19 booster shot side effects are mild, flu-like and temporary. ![]()
