The appearance of<unk>  is associated with infections such as acute tonsillitis, pneumonia, and gastroenteritis. Smallpox vaccination has been a known risk factor for myocarditis and pericarditis since the 1950s. In 1983, an incidence of myocarditis of 1 per 10 000 was reported among Finnish military personnel. Among US military service members vaccinated between December 2002 and March 2003 with Dryvax smallpox vaccine 18 cases of probable<unk>  were reported, which was an incidence of 7.8 per 100 000 over 30 days. A meta-review from 2022 shows that the overall risk for<unk>  after receiving a COVID-19 vaccine is low. In addition, the incidence of<unk>  is significantly higher with a smallpox vaccination in comparison with a COVID-19 vaccination. The ACAM2000 smallpox vaccine has been known to cause<unk>  in some people.
