A new study published on Friday raised concerns that heart disease could be a very rare side effect for teenagers and young adults receiving the second dose of COVID-19 vaccines.
Health officials are investigating whether reports of heart inflammation in seven U.S. teens in several states may be linked to the use of a Pfizer shot, the Associated Press reported.
The study, published in the Official Journal of the American Academy of Pediatrics, found that seven boys, aged between 1
Tests for imaging the heart showed a type of inflammation of the heart muscle called myocarditis.
None of the teenagers were seriously ill and they were all sent home from the hospital two to six days later, Dr Prieti Jagi, co-author of the report, told the AP. The inflammation is currently thought to be temporary, Jagie said.

The study follows news from Israel that suggests there is a “likely link” between taking the second dose of Pfizer vaccine and the onset of myocarditis, the Israeli Ministry of Health said on Tuesday.
Of the more than 5 million people who received the vaccine, 275 reported inflammation of the heart muscle, mostly young men, the health ministry said.
The US Centers for Disease Control and Prevention last month recommended investigating the link between myocarditis and mRNA vaccines, which include those from Pfizer and Moderna, said Sarah Al-Arshani of Insider.
However, the percentage of reported cases of myocarditis after vaccinations against COVID-19 does not differ from the baseline percentage, which means that there may be no link between vaccination and the condition, writes Al-Arshani.
Eligible teens are still encouraged to be vaccinated due to the growing number of hospitalizations among young people, the CDC said.
The CDC allows the use of the Pfizer vaccine for people 12 years of age and older.
In the UK, the national drug regulator has approved Pfizer’s COVID-19 vaccine for children aged 12 to 15.
