A recent study indicates that although most parents regard immunizations as important for their children's health, an increasing number are failing to make the connection between immunizations and the role they have played in eliminating many of the worst childhood diseases. According to Dr. Bruce G. Gellin of the Vanderbilt University School of Medicine, out of 1,600 parents questioned, approximately one-quarter felt that their child's immune system could be weakened as a result of too many immunizations, while 23 percent felt that children get more shots than are good for them. In his report in the journal Pediatrics, Gellin noted that nurses, doctors, and other medical personnel need to fight these growing misconceptions by boosting their attempts to educate parents about the efficacy and safety of immunization.
