During the Dec. 16 meeting of the CDC’s vaccine advisory panel, the CDC said there had been more than 7 million vaccine doses administered in the 5 to 11 age group at the time the agency examined the data, including 5.1 million first doses and 2 million second doses.

The CDC said there had been 3,233 reports to VAERS of adverse events among 5- to 11-year-olds, including 14 reports of myocarditis, five reports with follow-up in progress, nine reports with follow-up information obtained and eight reports of myocarditis that met the CDC’s working case definition, including four males and five females.

Two cases occurred after the first dose and six cases occurred after the second dose. One report is under review.
