Already in June, the US Medicines Agency raised concerns about the risk of myocarditis linked to the Novavax Covid-19 vaccine.

A technique used for vaccines against whooping cough, meningococcal meningitis and hepatitis B.
In June, six cases of myocarditis, an inflammation of the heart muscle, were actually diagnosed in the group of patients who received the vaccine, versus one case in the placebo group, which was later reported to the agency (FDA). Five cases occurred within two weeks of vaccination.
