If you have stroke risk factors, it’s also important to get your COVID-19 vaccine, as many stroke risk factors are associated with a higher risk of serious COVID-19 illness. The American Heart Association also encourages all heart attack and stroke survivors as well as those with heart disease and other cardiovascular risk factors to get vaccinated against COVID-19. Some research suggests that getting vaccinated against COVID-19 reduces your risk of major cardiovascular events like stroke if you do eventually develop COVID-19. As such, it’s a good idea for stroke survivors to get the COVID-19 vaccine to prevent serious illness. While few studies have assessed the risk of a second stroke after receiving the COVID-19 vaccine, a history of stroke increases your risk of severe COVID-19. Many of these involve the risk of blood clots or a second stroke. Is it safe to get the COVID-19 vaccine if you’ve had a stroke?Ī 2022 study revealed that some stroke survivors have concerns about COVID-19 vaccines. Other countries haven’t seen an increased rate of ischemic stroke with the bivalent vaccines yet.Īlso, initial studies using data from health systems in France and the United States have found no association between the bivalent vaccine and an increased rate of ischemic stroke in older adults.Ĭurrently, no change in vaccination practice is recommended by the CDC.Pfizer-BioNTech’s safety database hasn’t identified a safety signal for ischemic stroke with their bivalent vaccine.There hasn’t been an increase in reports of ischemic stroke in the Vaccine Adverse Event Reporting System after the introduction of the bivalent vaccine.Two studies that haven’t been published yet on bivalent vaccines using data from the Centers for Medicare and Medicaid Services database and Veterans Affairs database haven’t found an increased prevalence of ischemic stroke.The announcement goes on to say that no other safety systems or analyses have observed this signal: A similar safety signal wasn’t seen with the Moderna bivalent COVID-19 vaccine. This signal, triggered by the CDC’s Vaccine Safety Datalink, involved a potentially higher risk of ischemic stroke in adults ages 65 years old and older. Bivalent vaccines contain more than one strain of SARS-CoV-2, the virus that causes COVID-19. Bivalent COVID-19 vaccines and stroke riskĮarlier this year, the CDC and the Food and Drug Administration (FDA) announced an investigation into a safety signal for the Pfizer-BioNTech bivalent COVID-19 vaccine. The Centers for Disease Control and Prevention (CDC) estimates that TTS happens with every four out of a million doses of the J&J vaccine.ĭespite the rarity of TTS, a CDC advisory committee stated that other vaccines are preferred over the J&J vaccine due to their improved safety profile. These blood clots can potentially cause a stroke. TTS causes low platelet counts and blood clots in your large blood vessels. Thrombosis with thrombocytopenia syndrome (TTS) is a very rare, but serious, side effect that’s associated with the Johnson & Johnson (J&J) COVID-19 vaccine, a type of viral vector vaccine. COVID-19 vaccines and thrombosis with thrombocytopenia syndrome The researchers state that this is similar to the prevalence of stroke in the general population. the type or combination of mRNA vaccines receivedĪnother 2022 review found that the prevalence of ischemic stroke after any COVID-19 vaccine was 4.7 per 100,000 doses.It didn’t find a higher rate of stroke in the 28 days after vaccination. So far, many have found that there’s no increase in the prevalence of stroke after getting the COVID-19 vaccine compared with stroke rates in the general population.įor example, a 2023 study looked at stroke risk after vaccination with mRNA COVID-19 vaccines in more than 4.1 million people. Researchers have continued to study stroke risk after COVID-19 vaccination. What is the risk of stroke after the COVID-19 vaccine?
