Immunization practices and knowledge of vaccine contraindications amon
g pediatric residents were assessed at five pediatric training facilit
ies by surveying 227 pediatric residents. Residents administer vaccine
s even in the presence of an afebrile minor illness. They are less lik
ely to vaccinate if a fever (<102 degrees F) is present. Only 57% of r
esidents report administering vaccines at the 15-month well-child chec
ks, Many residents had difficulty recognizing true and false contraind
ications, though third-year residents did better than first-year resid
ents. Failure during residency to utilize 15-month well visits and ill
visits in the presence of a fever and the lack of knowledge of true a
nd false vaccine contraindications may be causes of missed opportuniti
es to vaccinate among residents. Immunization practices resulting in m
issed opportunites to vaccinate seen during during residency may influ
ence later immunization practices.
