Benefits of COVID-19 vaccination outweigh risks of rare cases of myocarditis: Study
DALLAS - The benefits of the COVID-19 vaccine outweigh the low risk of developing myocarditis after receiving the COVID-19 vaccine, according to research published today in Circulation, the flagship journal of the American Heart Association
Last month, the U.S. Centers for Disease Control and Prevention (CDC) identified a "likely association" between the two COVID-19 mRNA vaccines, from Pfizer-BioNTech and Moderna, and cases of suspected myocarditis and pericarditis. Most of the suspected cases of myocarditis developed after the second dose of a COVID-19 vaccine and were among younger males (between the ages of 12-39 years).
Researchers conducted an analysis of data from the CDC's Vaccine Adverse Event Reporting System (VAERS) and from multiple peer-reviewed scientific journal articles to compare vaccination rates to reports of myocarditis among people who received the COVID-19 vaccine through mid-June 2021. The analysis found:
- Most people suspected to have myocarditis presented with chest pain, usually 2-3 days after a second dose of a COVID-19 mRNA vaccination.
- Some people suspected to have myocarditis experienced fever and muscle pain the day after their vaccination.
- Those affected and requiring hospitalization for suspected myocarditis were mostly young males (ages 12-19) without a prior history of COVID-19 or other health conditions.
- All tested negative for COVID-19.
- Most patients were discharged from the hospital as their symptoms, diagnostic and imaging signs of the condition returned to normal, either with or without treatment.
