What isbeing done to investigate the hair loss finding or other reactions from vaccine

The Centers for Disease Control and Prevention (CDC) in collaboration with the Food and Drug Administration (FDA) will continue to investigate the possible association between vaccine and hair loss along with other vaccine reaction questions.

The CDC and FDA will continue to evaluate the results of this study using more detailed and powerful statistical methods. Researchers plan to check the results of the original research and investigate the risk factors. Information from the Vaccine Safety Datalink (VSD) will be used to conduct one follow up study. The Vaccine Safety Datalink project was created by CDC in 1991 to permit detailed scientific assessment of vaccine safety concerns. This successful project has linked computerized vaccination and medical records of more than one million children in four Health Maintenance Organizations (HMO's). Approximately 6 million people in the U.S. participate in the VSD project. The data gathered for VSD project is expected to help answer questions about possible side effects associated with vaccines.
