Pertussis immunization patterns in special care nursery graduates

Abstract

Controversy exists regarding immunization with pertussis vaccine of high-risk special care nursery graduates. Our study compared the immunization status of 38 high-risk, 30 low-risk, and 57 normal infants utilizing an immunization response form. Comparison of the three infant groups revealed that complete or incomplete immunization varies, depending on group status. Of 38 infants at high risk for developmental delay, 22 (57.9%) were not immunized against pertussis by age one. Physicians cited concerns related to previous neurologic injury and increased liability for vaccine-related injury as major reasons for deferring vaccination. Recommendations for improving current guidelines and practice are outlined.
