Missed opportunities result in under-vaccinated children and adults. Clinicians often mistakenly elect not to give a vaccine thinking that a contraindication exists.
Answer: Of the scenarios listed, only D. (HPV administration to a pregnant mother in her third trimester) is a conraindication to vaccine administration per the CDC.
HPV should not be given during any of the trimesters. However, the package insert, controlled by the FDA, considers F as a contraindication. Why can't these two government agencies get together and agree on the same recommendations? That's a story for another time.
