![]() Some people who’ve developed myocarditis after a viral infection can develop scarring in the heart, reducing its ability to pump blood and circulate oxygen around the body. Pfizer and Moderna are both conducting long-term clinical trials to track possible health issues in the years following a diagnosis of vaccine-associated heart problems in teens and young adults. The study also doesn’t give insight into what long-term health problems - if any - people may experience following vaccine-induced myocarditis, which is often milder than the kind caused by viral or bacterial infections. Nor do they explain why the condition affects men more than women. ![]() The findings don’t explain why the inflammation only appears to affect the heart and not other organs, Lucas, the senior study author, said. A CDC study published in January that looked at children ages 5 to 11 found no cases of myocarditis following a booster dose of the bivalent vaccine. after the Food and Drug Administration switched to the updated bivalent formula and moved away from a two-dose primary series. Those vaccines, however, are no longer in use in the U.S. Most cases that do occur are in male teens and young adults, usually after the second dose of a primary series of either the original version of the Pfizer-BioNTech or Moderna vaccine. In teens ages 16 and 17, there have been 316 confirmed cases after more than 14 million vaccine doses were administered. As of March 2, there have been 376 confirmed cases of myocarditis in children ages 12 to 15 after more than 25 million vaccine doses were administered, according to the agency. Myocarditis (inflammation of the heart muscle) or pericarditis (inflammation of the lining of the heart) following Covid vaccination is very rare, according to the Centers for Disease Control and Prevention. The findings, he said, suggest that one potential treatment for the inflammation could be a drug that targets the body's excess immune response after vaccination. Cooper was also not involved with the new research. Leslie Cooper, the chair of the cardiology department at the Mayo Clinic in Rochester, Minnesota, said the study, though small, is “an important contribution to our understanding of the mechanisms” of vaccine-induced myocarditis in young men. It is very important that you tell staff at the vaccination center if you have ever had an allergic reaction to a vaccination or any ingredients in the vaccine.Dr. People given a COVID-19 vaccine are often asked to wait for 15-30 minutes after receiving their vaccination, in case a reaction should occur, so that staff can treat it quickly. The allergic reaction can often be treated by epinephrine (an EpiPen). Symptoms of an allergic reaction include face and throat swelling a rash and a low blood pressure. These generally happen in people who have previously had allergic reactions to other vaccines. In some rare cases, people can have allergic reactions to vaccinations. 4 Allergic reactions to the COVID-19 vaccine You should also speak to your doctor if the injection site gets redder or more tender after 24 hours. If you are still experiencing discomfort or pain after that time, or if you are worried about how you are feeling, get in touch with your doctor.

Speak to the vaccination team or your doctor about what you might take. 2,3 Paracetamol may help alleviate any side effects you experience. 3 If you are having other side effects beyond discomfort in your arm, drinking fluids and resting can help. 2 Treating side effectsĪpplying a cool, clean wet cloth on the injection site and using and gently exercising your arm can help alleviate any soreness you feel. Remember that any side effects that you feel are because your body is reacting to the vaccine and building an immune response. Soreness in the arm where the injection was given.Pain or tenderness at the injection site.2,3,4ĬOVID-19 vaccination side effects include 2,3,4: In rare cases, they have been known to last up to a week. They usually last a day or two and get better on their own. Side effects associated with COVID-19 vaccinations are generally mild. 2 Common side effects to the COVID-19 vaccine These side effects show that your body is getting ready to protect itself from coronavirus, and building immunity to fight the virus. As with most vaccinations, some people who have received the various approved COVID-19 vaccines have reported side effects. It is important to get your second vaccination to complete the inoculation, despite any side effects that you may have felt.ĬOVID-19 vaccinations are designed to protect us from coronavirus. The vaccines usually come in two shots.Vaccines provide immunity to diseases.Side effects are a sign that your body is beginning to build immunity. When you are vaccinated, your body responds by preparing to protect itself.
