The safety of coronavirus vaccines has been proven

Pfizer and Moderna were not associated with serious health consequences.

Pfizer and Moderna RNA vaccines against coronavirus are not associated with any serious health consequences and are safe. This was proved by specialists of the non-profit organization Kaiser Permanente, who studied the medical records of 6.2 million patients. This is reported in a press release on EurekAlert.

The study presents the results from mid-December 2020 to June 26, 2021. Some of them were summarized earlier and reported at open meetings of the Advisory Committee of the Centers for Disease Control and Prevention of the United States (CDC) on immunization practices.

The analysis compared specific events among all people vaccinated with the COVID-19 RNA vaccine during the first three weeks after vaccination with health events among patients for 3-6 weeks after vaccination. The total number of people evaluated was 6.2 million for the first dose of any RNA vaccine and 5.7 million for the second dose. The researchers examined 23 potential health effects, including encephalitis and myelitis, seizures, Guillain-Barre syndrome; cardiovascular problems such as acute myocardial infarction, stroke, and pulmonary embolism; and others, such as Bell’s palsy, appendicitis, anaphylaxis, and multisystem inflammatory syndrome.

The researchers then applied statistical analysis to determine whether the number of incidents was above a certain threshold or “signal,” which would indicate a high risk of serious health consequences. It turned out that none of the targets reached the threshold. The authors also calculated that among patients aged 12 to 39 years, there is a risk of an additional 6.3 cases of myocarditis per million doses during the first week after vaccination.
