NATIONWIDE —As medical leaders nationwide push for Americans to roll up their sleeves and get their COVID-19 shots, there is a growing concern among some parents after a potential link between heart ailments in young people and the vaccine.

The CDC's advisory committee on immunization practices will be meeting this week to talk about mRNA-based vaccines, which are the Pfizer and Moderna vaccines, in teenagers and young adults. The committee is also scheduled to look at reports that some young people reported inflammation of the heart days after getting their second shot.

Most cases have been reported in young men 16 years old and older in the days after getting their second shot.
