According to the EMA, conditions including myocarditis and pericarditis must be listed on the side effects list of the two vaccines.
These events mainly occurred within 14 days of injection and usually occurred after the second dose, in young adult male subjects. This finding is similar to the findings of the US last month. Symptoms of myocarditis include shortness of breath, palpitations, and chest pain.
While the EMA warns to watch out for symptoms after getting a Covid-19 vaccine, the agency stressed it will continue to monitor the safety of approved vaccines as they become more widely deployed.

In total, the EMA looked at more than 300 cases of myocarditis and pericarditis in the EU, Iceland, Norway and Liechtenstein. Most of the cases occurred with Pfizer’s vaccines.
By May 31, these countries had received a total of 177 million doses of Pfizer’s Covid-19 vaccine. According to Pfizer’s statement, cases of myocarditis and pericarditis are “generally mild” and individuals “tend to recover for a short time after treatment and rest.”
The vaccines from Johnson & Johnson (J&J) and AstraZeneca are also monitored by the EMA, but the EMA has not found a link between myocarditis and these vaccines.
In addition, the EMA Safety Committee also recommends that people with a history of a rare blood disorder, capillary leak syndrome (CLS), should not be immunized against COVID-19 with the J&J vaccine.
In June 2021, the EMA recommended that CLS be listed as a side effect of the AstraZeneca vaccine.
