![]() 94% effective at preventing COVID-19 hospitalizations and deaths among fully vaccinated adults.95% effective at preventing coronavirus infection.When first studied in earlier coronavirus variants, COVID-19 vaccines were shown to be roughly: However, if you or your child has experienced myocarditis after a vaccine before, discuss your options with your doctor before getting vaccinated. This is because they’re at a much greater risk of heart-related complications from the coronavirus than they are from any COVID-19 vaccine. The American Heart Association recommends that anyone with heart disease get vaccinated against COVID-19 as soon as possible. Vaccination for people with preexisting heart conditions This risk of myocarditis did appear to be a bit higher after a second dose of the Moderna vaccine - not the other vaccines studied - and was only observed in people younger than 40.Įven though arrhythmias are sometimes associated with myocarditis, no direct association was found between arrhythmia and COVID-19 vaccination. This research included the Oxford-AstraZeneca vaccine as well as the Pfizer-BioNTech and Moderna vaccines. ![]() It also found slightly increased risks of heart inflammation after participants’ first and second doses of COVID-19 vaccines in the first 28 days after vaccination. In other words, this side effect is exceedingly rare.Īnother 2021 study involved people ages 16 and up who were vaccinated against COVID-19. Traditional vaccines, like the Johnson & Johnson COVID-19 vaccine, contain genetic material from the virus, which also helps your body create antibodies.Ī 2021 analysis of CDC data found that people ages 12 to 39 who received their second COVID-19 mRNA vaccine had about a 13 in 1 million chance of experiencing heart inflammation. These vaccines contain genetically engineered mRNA that teaches your cells how to create antibodies capable of fighting the coronavirus that causes COVID-19. ![]() The Pfizer-BioNTech and Moderna vaccines are messenger RNA (mRNA) vaccines. This side effect hasn’t been observed in people who received the Johnson & Johnson vaccine. These heart issues occurred mostly in males between ages 12 and 39 after they received the second dose of the vaccine, usually within a few days of receiving the vaccine. They can help you make an informed decision for your specific situation.Data from the Centers for Disease Control and Prevention (CDC) shows that higher than normal cases of heart inflammation have been reported in the United States after COVID-19 vaccination with the Pfizer-BioNTech or Moderna vaccines. Talk to your healthcare provider about the potential benefits and risks of receiving an RSV vaccine. It isn’t clear if the early births happened because of the vaccine, or other reasons. During clinical trials, a small increase in preterm births were observed in pregnant women who got Abrysvo. This is when your baby is born before 37 weeks of pregnancy. Get immediate medical attention if these develop.Īnother possible complication that could happen after getting an RSV vaccine during pregnancy is preterm birth. Symptoms can include persistent or severe headaches, vision changes, or swelling in your face or hands. Preeclampsia usually happens around the last month of pregnancy, which is when you would receive Abrysvo. But the rate of preeclampsia was slightly higher in the Abrysvo group. Some pregnant women, including those who received Abrysvo and those who did not, developed preeclampsia. Preeclampsia is a condition during pregnancy that causes dangerously high blood pressure. Are there potential risks for pregnant women? Get medical help right away if you notice any of these symptoms.Ī few other rare, but serious side effects reported after vaccination include atrial fibrillation (abnormal heart rhythm) and a rare type of brain and spinal cord inflammation. The risk of this happening is low, but watch out for signs such as rash, swelling in your face or throat, and trouble breathing. Severe allergic reactions (anaphylaxis) are possible with any vaccine. Symptoms of GBS include muscle weakness, a “pins and needles” feeling, and problems with balance. More research is needed to know if the risk of GBS is higher after getting an RSV vaccine. With both Abrysvo and Arexvy, there were a few reports of a serious neurologic condition called Guillain-Barré syndrome (GBS). While it’s not clear if they were actually caused by the vaccine, it’s important to be aware of them. Some people who received an RSV vaccine during clinical trials experienced serious side effects, although this was very rare.
