An increased risk of heart diseases was observed after Covid-19 mRNA vaccination and was highest in men aged 18–25 years after a second dose of the vaccine, a study funded by American health regulator US FDA found.
“These results do not indicate a statistically significant risk difference between mRNA-1273 (Moderna vaccine) and BNT162b2 (Pfizer BioNTech vaccine), but it should not be ruled out that a difference might exist,” said the study published in Volume June 11.
The study used active surveillance from large healthcare databases to quantify and enable the direct comparison of the risk of myocarditis or pericarditis, or both, after Moderna and Pfizer–BioNTech vaccinations.
Among men aged 18–25 years, the pooled incidence rate was highest after the second dose, at 1·71 per lakh person-days for Pfizer and 2·17 per lakh person-days for Moderna.
