Match each pediatric patient's clinical presentation or medical history with the most appropriate vaccine management decision.
- A 4-month-old infant presenting for well-child care with a history of surgically reduced intussusception.Administration of the rotavirus vaccine is strictly contraindicated.
- A 15-month-old child presenting for well-child care who is currently receiving maintenance chemotherapy for acute lymphoblastic leukemia.Administration of all live-attenuated vaccines is strictly contraindicated.
- A 9-month-old infant presenting prior to international travel to an area with endemic measles.Administration of the MMR vaccine is indicated, though the dose will not count toward the routine two-dose series.
- A 12-month-old child with a history of anaphylaxis to eggs presenting for an initial influenza vaccination.Administration of the age-appropriate influenza vaccine can proceed without special precautions.
- A term newborn delivered in the hospital to a mother with a documented positive hepatitis B surface antigen (HBsAg) test.Administration of hepatitis B vaccine and hepatitis B immune globulin is required within 12 hours.
Answer
The correct matches pair the infant with intussusception to the rotavirus vaccine contraindication; the child on chemotherapy to the live-attenuated vaccine contraindication; the 9-month-old traveler to early MMR vaccination; the child with an egg allergy to routine influenza vaccination; and the newborn of an HBsAg-positive mother to immediate active and passive HepB immunization.
The correct pairings accurately reflect current evidence-based immunization guidelines. A history of intussusception specifically contraindicates the rotavirus vaccine due to recurrence risk. Severe immunocompromise (e.g., active chemotherapy) universally contraindicates all live-attenuated vaccines. Infants between 6 and 11 months traveling internationally should receive an early MMR dose to provide temporary protection, though it does not count toward the routine series. An egg allergy is no longer a contraindication to the influenza vaccine. Newborns of HBsAg-positive mothers require both the HepB vaccine and HBIG within 12 hours of birth.
