The mRNA COVID-19 vaccinations were administered to children aged 12–15 as well as 16–17 years who had post-vaccination cardiac myocarditis, according to a non-peer-reviewed retrospective study published as a pre-print in JAMA Internal Medicine.

Is The Vaccination Linked With An Increased Heart Disease Rate In Boys?

From January 1, 2021, until June 18, 2021, the researchers searched the Vaccine Arterial Dissection Reporting for reports of vaccine-related adverse events involving youth aged 12-17 years. Myocarditis and pericarditis were among the terms used in the search. They also looked for a troponin lab that may also detect heart attacks and other cardiac disorders, as well as chest discomfort.

They subsequently concluded that these youngsters had had cardiac adverse events (CAEs) based on their findings. Following the administration of the COVID-19 vaccine, the CDC stated in June 2021 that it is constantly watching for the development of myocarditis as well as pericarditis in the population. The Centers for Disease Control and Prevention (CDC) continues to recommend that everybody aged 12 and older get a COVID-19 vaccine.

Researchers divided the data they had classified as CAE rates into three groups based on age, gender, and the number of vaccine doses received. It was decided to perform a harm-benefit assessment based on existing research on hospitalization risk associated with COVID-19 among people in the age range studied.

In all, 257 CAEs were detected, with rates (measured in cases per million that after the second dosage) of 162.2 in kids aged 12–15 years, 94 in kids aged 16–17 years, 13 in females aged 12–15 years, as well as 13.4 in females aged 16–17 years reported.

Among healthy boys aged 12–15 who received their second mRNA dosage, the researchers projected that the incidence of CAE was around 3.7 and 6.1 times greater than the 120-day COVID-19 hospitalization risk (August 21, 2021), according to the findings. They calculated that the incidence of CAE was 2.1–3.5 times greater in healthy males aged 16–17 than in the general population.

An infection, medications, autoimmune disorders, or environmental factors may all induce inflammation in the heart, which can cause damage and result in health issues. Inflammation can develop in the heart as a result of several causes. Inflammation of the heart tissue (myocarditis) and the tissue that surrounds the heart (pericarditis) is both possible (pericarditis).

Male teenagers and young adults were the most commonly affected, with the majority of cases occurring within 7 days of receiving the 2 doses of an mRNA COVID-19 immunization (Pfizer-BioNTech and Moderna). The majority of cases were resolved with conservative management, with the exception of one case that required hospitalization.

VAERS collects patient and family reports of adverse events following vaccination, a post-marketing safety program in the United States that gathers reports of adverse events following immunization from patient populations, relatives, health professionals, drug manufacturers, as well as the general public in the United States.

The study’s shortcomings include the improper usage of VAERS report data to determine the CAE rate, which was discovered throughout the research. VAERS is designed to identify safety signals, as well as unexpected trends of vaccine-related adverse events, in real-time.
