Vaccines: Delays, Too, Pose Risks

A 2013 study in JAMA Pediatrics found a big risk of contracting pertussis or whooping cough with each delayed vaccine dose, said Jason Glanz, a vaccine researcher with Kaiser Permanente Colorado and a lead author of the study. The study looked at 323,247 children from eight managed-care organizations in six states. “For every dose that was delayed, the risk went up significantly,” said Dr. Glanz. “At the highest it was a 28-fold greater risk.” Dr. Douglas Opel, a pediatrician at Seattle Children’s, finds himself once a month in negotiations with parents about vaccines. About half the time he is successful.
