Moderna side effect stats9/17/2023 ![]() Altogether, there was an average of 4.2 cases per 100,000 people. Meanwhile, those who had received Moderna vaccines were significantly more likely to develop myocarditis or myopericarditis in the 28 days after vaccination, compared with unvaccinated individuals. Of these, 40% were 12–39 years old, and 73% were male.Īltogether, the rate of developing myocarditis or myopericarditis within 28 days of any SARS-CoV-2 mRNA vaccine was 1.7 per 100,000 vaccinated individuals.Īmong those who had received the Pfizer vaccine, the researchers noted, the rate of myocarditis or myopericarditis was 1.4 cases per 100,000 individuals - with 1.5 cases per 100,000 males, which was not significant, and 1.3 per 100,000 females, which was significant. The remaining 4.2% had received Johnson & Johnson vaccines.Īt follow-up, 269 people had myocarditis or myopericarditis. When analyzing the data, the researchers excluded people who had received different kinds of vaccines and people with positive SARS-CoV-2 test results to avoid confounding outcomes of contracting the infection.īy the end of the period, 83.8% of individuals had received Pfizer vaccines and 12% had received Moderna vaccines. They followed the participants for 28 days after both their first and second vaccine doses, between October 1, 2020, and October 5, 2021. In addition, the researchers included data about SARS-CoV-2 polymerase chain reaction (PCR) tests from the Danish Microbiology Database.Īltogether, the researchers included 4,931,775 individuals in their study. These are a marker for myocarditis, and doctors detect this marker in over a third of people with the condition. The team incorporated data from blood samples kept by the Register of Laboratory Results for Research to characterize cases of myocarditis or myopericarditis via measurement of troponin levels. The researchers combined data about vaccinations from the Danish Vaccination Register with data about hospital-based diagnoses from the country’s National Patient Register to visualize post-vaccine health outcomes for Denmark’s entire population over 12 years old. However, why this vaccine causes myocarditis is still unknown,” she confirmed. Myocarditis has been reported with other vaccines in the past, so it is also not surprising to find with this vaccine. “This study also confirms that these cases are mild, similar to data from the U.S. Stempien-Otero was not involved in the recent research. April Stempien-Otero, a cardiologist at the University of Washington Medical Center’s Heart Institute, in Seattle, told Medical News Today. “The percentage of myocarditis cases associated with vaccination is not surprising, as it is very similar to studies in the United States and Israel,“ Dr. ![]() However, the absolute rates of these conditions after the vaccinations were low. They found that mRNA vaccination against COVID-19 was linked to a significantly increased risk of both heart conditions. In a recent study, researchers from Denmark analyzed national healthcare data to identify links between mRNA vaccination and a diagnosis of myocarditis or myopericarditis. Currently, little publicly available research has assessed the incidence of the conditions in a complete population. The Centers for Disease Control and Prevention (CDC) and the European Medicines Agency are engaged in ongoing investigations to confirm and clarify any link. However, scientists have observed a similar link with the smallpox vaccine in adults. The underlying cause of the link between COVID-19 vaccines and myocarditis is unclear. ![]() Evidence suggests that it occurs especially after the second booster dose of the Pfizer and Moderna mRNA vaccines. The inflammation is usually triggered by viral, bacterial, or fungal infection. ![]() In the most severe cases, both conditions can lead to heart failure and death. Myocarditis is inflammation of the heart muscle, while myopericarditis is inflammation of the membrane around the heart. Previous research has suggested a link between SARS-CoV-2 vaccination and myocarditis and myopericarditis. ![]()
