Coronavirus: US experts investigate heart problems among teens after shots
- Reports of chest pains after second dose of an mRNA vaccine
- US experts say cases are ‘rare’ but were still cause for concern

The committee, hosted by the Centres for Disease Control and Prevention (CDC), will hear a risk-benefit analysis as researchers explore whether the shots can cause myocarditis, as well as cases of inflammation of the heart lining, pericarditis.
Israel was the first country to identify a possible link.
“These cases are rare, and the vast majority have fully resolved with rest and supportive care,” said CDC director Rochelle Walensky last week ahead of the meeting on Wednesday, which was initially scheduled for last Friday but postponed because of a new public holiday.
The cases that have been confirmed were investigated following initial reports to vaccine safety monitoring systems, and come from more than 20 million adolescents and young adults that have been vaccinated, added Walensky.
