According to Reuters, the US Food and Drug Administration (FDA) said on June 23 local time that the Pfizer and Modena vaccines have the risk of triggering heart inflammation in adolescents and young adults, and will add this warning message in the vaccine description as soon as possible.

The Pfizer and Modena vaccines are vaccines developed using MNAs (messenger ribonucleic acid) technology, a new way of making vaccines, and health regulators in several countries have been investigating whether vaccines developed with this technology are at risk and, if so, how much risk. Previously, the U.S. Centers for Disease Control and Prevention (CDC) has warned doctors and hospitals to pay attention to the symptoms of myocarditis or pericarditis after vaccination, and the FDA's warning will further raise people's vigilance.
According to reports, according to the data of cdc in the United States, within 1 week after receiving the second dose of Pfizer or Modena vaccine, the number of cases of heart inflammation in male vaccinators increased significantly. CDC in the United States confirmed 309 patients with heart inflammation under the age of 30, of whom 295 have been discharged from the hospital. Dr. Tom Shimabukuro, deputy director of the Office of Immune Safety at cdc in the United States, noted that according to the agency's vaccine safety database (VSD), the incidence in people aged 12 to 39 years was 12.6 parts per million within 3 weeks after receiving the second dose, with more men than women, while people aged 50 and older were hardly affected by this.
Data from the Vaccine Adverse Event Reporting System (VAERS) in the United States also show that 347 of men aged 12 to 24 developed heart inflammation within 1 week of the second vaccination. The US CDC pointed out that according to the background incidence of the US population, there should be fewer than 12 cases of heart inflammation in men aged 12 to 24 years.
However, CDC said that patients who develop heart inflammation after vaccination usually recover health. The U.S. Department of Health and Human Services, the leading U.S. physicians' organization, and U.S. public health officials also issued a joint statement stressing that vaccines are safe and effective and that heart inflammation is an "extremely rare" side effect.
Reuters said israel's health ministry had said earlier this month that such cases could be linked to Pfizer's COVID-19 vaccine.
After the US FDA issued this warning, the stock prices of Pfizer and Modena fell in response. In response, Pfizer said it did not observe an increase in the incidence of heart inflammation after people received the Pfizer vaccine. Modena said it had taken note of reports of such cases and was working with public health and regulators to assess the issue.
