The CDC and FDA require additional information on selected VAERS reports for the public health purpose of helping to ensure the safety of U.S. licensed vaccines. You or your health care provider may be contacted for follow-up information by VAERS staff after your report is received. These selected reports are followed up by a team of health care professionals to obtain additional information (such as medical records and autopsy reports) to provide as complete a picture of the case as possible.
