Childhood vaccines may cause hair loss

US doctors investigating reports of hair loss in children after immunisation have found it is a common complaint unacknowledged by the Food and Drug Administration (FDA) .

Dr Robert Wise and associates identified 60 cases of hair loss between 1978 and 1995, though the FDA only had nine on file. One mother told the FDA her child's hair fell out on two separate occasions shortly after injections of the hepatitis B vaccine.

Dr Samuel Sepkowitz from Oklahoma City, Oklahoma, says since the report was published he has been notified of an average of one case of hair loss due to vaccination per week (JAMA, 1998; 279: 117-8).
