in the United States, they are investigating cases of myocarditis after the application of the second dose of Pfizer

Health officials in the United States are trying to determine whether heart inflammation that can occur in conjunction with many types of infections could also be a rare side effect. in adolescents and young adults after the second dose of the COVID-19 vaccine.

An article on seven American adolescents in various states, published in Pediatrics, is among the latest reports inflammation of the heart discovered after COVID-19 vaccination, although a link with the vaccine has not been proven.

The children, aged 14 to 19, received Pfizer injections in April or May and developed chest pain within days. Imaging tests of the heart have shown a type of inflammation in the heart muscle called myocarditis.

No serious case

None was seriously ill. They were all healthy enough to be sent home after two to six days in the hospital and they are doing quite well, ”said Dr Preeti Jaggi, infectious disease specialist at Emory University and co-author of the report.

The cases echo the Israel reports in young men diagnosed after receiving Pfizer injections.

The US Centers for Disease Control and Prevention alerted doctors last month that they were monitoring a small number of reports of heart inflammation in teens and young adults after vaccines against MRNA, of the type manufactured by Pfizer and Moderna.

The CDC has not determined if there is really a link to vaccines and continues to urge that all people over 12 years old get vaccinated against COVID-19, which is much riskier than the vaccine.

The Pfizer vaccine is available for children under 12; The modern vaccine remains authorized adults only, although in tests it has been found to be effective in young people as well.

This type of heart inflammation can be caused for a variety of infections, including a COVID-19 attack, as well as by certain drugs, and there have been rare reports after other types of vaccines.

Authorities will need to determine whether post-vaccination COVID-19 cases are occurring more frequently than the expected “baseline rate.”

After the second dose

For now, the CDC says that most patients they were men, reported symptoms after the second dose and their symptoms improved quickly.

“I think we are in the waiting period where we have to see if it is cause and effect or not,” said John Grabenstein of the Immunization Action Coalition, former director of the immunization program at the Ministry of Health. Defense.

Guys infected with covid

A Pediatrics editorial noted that among American children under the age of 18, there were more than 4 million cases of COVID-19, more than 15,000 hospitalizations and at least 300 deaths.

He said that cases of heart inflammation require more research, but added that “the benefits of vaccination against this deadly and highly transmissible disease clearly outweigh the potential risks.”

Editorial co-author Dr. Yvonne Maldonado, chair of the American Academy of Pediatrics Infectious Disease Committee, is involved in studies of the Pfizer vaccine, including a study of the COVID-19 vaccine in children .
