What other vaccines have been studied?
For the studies examined in the meta-analysis 22 (405,272,721 vaccine doses), a myopericarditis incidence of
- 33.3 cases per million vaccine doses detected (95% CI 15.3 – 72.6).
However, the type of vaccination does not seem to be decisive. In the COVID-19 group, the incidence was
- 18.2 (10.9-30.3; 11 studies, 395,361,933 vaccine doses, high safety),
in the group vaccinated with other vaccines
- 56.0 (10.7-293.7, 11 studies 9,910,788 vaccine doses, intermediate safety).
Specifically, the latter was regarding smallpox and influenza vaccinations, for example. Six studies reported 2,900,274 doses of smallpox vaccine, two studies reported 1,521,782 doses of influenza vaccine, and three studies reported a variety of non-COVID-19 vaccines (such as varicella, yellow fever, oral polio vaccine, measles, mumps, and rubella, meningococcal, diphtheria, whooping cough and tetanus, BCG, hepatitis and typhoid; 5,488,732 doses).
