We do not know the risk of myocarditis or other rare side effects after a booster dose yet. 1 additional case for every 17,500 men aged 16 to 24 (within 28 days).1 additional case for every 38,000 men aged 12 to 29 (within 7 days).The risk of these very rare conditions is higher in young men.Ģ European studies have estimated the risk of myocarditis in men, after the second dose of the vaccine as: They have mostly been seen within 14 days of getting the vaccine. These conditions are more likely to happen after the second dose.
Myocarditis and pericarditis are inflammatory heart conditions. Very rare side effects may affect up to 1 in 10,000 people. The Pfizer/BioNTech COVID-19 vaccine is called Comirnaty. Pfizer/BioNTech COVID-19 vaccine side effects The side effects of the COVID-19 vaccines used in Ireland are listed below. If you have had anaphylaxis (severe allergic reaction) to Trometamol, you should not get the adapted mRNA vaccines. The safety of the vaccines will continue to be monitored by the European Medicines Agency (EMA). We expect that the side effects of the adapted (bivalent) mRNA vaccines will be similar to the previous Pfizer/BioNTech and Moderna COVID-19 vaccines. There have not been any unexpected side effects for people who have had multiple boosters. Many countries have given multiple doses of COVID-19 vaccines. If you feel uncomfortable, take paracetamol or ibuprofen following the instructions on the box or leaflet. This usually happens within 48 hours of getting a vaccine. It’s common to develop a fever (temperature of 38 degrees Celsius or above) after COVID-19 vaccination. Your vaccinator is trained to treat allergic reactions. Serious side effects, like a severe allergic reaction, are extremely rare.
If you are concerned about side effects, phone your GP for advice. Most of these are mild to moderate and short-term.

"There's some evidence that the rates and severity of the Pfizer vaccine in the booster are almost identical to the second dose," Boston Medical Center's Dr. Israeli data suggests that the booster shot might be a little bit easier to tolerate than the second dose, Dr. Will the booster side effects be as bad as the second dose? The data available for J&J was more limited, but people reported fever, fatigue and headache after receiving a second dose of that vaccine, according to the agency. "I'm certainly hearing a lot about that, you know, and it may be more than the first and second shot but it is harmless." Shira Doron of Tufts Medical Center said. "With the Pfizer booster, and I think this has been confirmed, there appears to be a fair amount of swelling of the lymph nodes in the underarm area on the side of the vaccine," Dr. The most common side effects reported after getting a third shot of an mRNA vaccine, the type made by Moderna and Pfizer, were pain at the injection site, fatigue, muscle pain, headache and fever, followed by chills and nausea.
