Pfizer and Modern mRNA vaccines can cause myocarditis.
–
Such events occur mainly within 14 days after vaccination, and the symptoms are shortness of breath, palpitations and chest pain.
The European Medicines Regulatory Authority has found a possible link between the very rare inflammation of the heart and the mRNA vaccines against COVID-19 produced by Pfizer and Modern, Reuters reported.
However, the drug agency believes that the benefits of vaccines outweigh the risks and advises that vaccinations be continued.
Heart disease, myocarditis and pericarditis, should be listed as possible side effects of the two mRNA vaccines, the European Medicines Agency (EMA) Safety Committee said, adding that such events occur mostly within 14 days of vaccination. Symptoms include shortness of breath, palpitations and chest pain.
Conditions for side effects are more common after the second dose and in younger adult men. Similar conclusions were reached by US health authorities in June.

The EMA has examined more than 300 cases of myocarditis and pericarditis in the European Union, Iceland, Norway and Liechtenstein. Most occurred after immunization with the Pfizer vaccine, according to a statement from the EU’s drug agency, but it is also more widely used.
So far, the EMA has not found a similar causal link between the Astra Zeneca and Johnson & Johnson vaccines.
A statement from vaccine maker Pfizer said myocarditis was mild and people were recovering “shortly after standard treatment and rest.”
“The EMA confirms that the benefits of all authorized vaccines against COVID-19 continue to outweigh the risks,” the drug agency said in a statement.
The EMA’s safety panel also recommended that people with a history of a rare blood disorder called capillary leakage syndrome (CLS) should not be vaccinated with a single Johnson & Johnson vaccine after reviewing information on three cases. occurred within two days after vaccination. In June, a similar possible side effect was added to the Astra Zeneca vaccine leaflet.
