Match each pediatric patient presentation with the most appropriate immunization recommendation or contraindication based on their specific health status.
- A 2-year-old child with sickle cell disease who has completed the routine infant pneumococcal conjugate vaccine seriesAdminister the 23-valent pneumococcal polysaccharide vaccine (PPSV23)
- An 11-year-old child with a newly diagnosed terminal complement component (C5-C9) deficiencyAdminister the meningococcal serogroup B (MenB) vaccine
- A 6-year-old child currently receiving induction chemotherapy for acute lymphoblastic leukemiaAbsolute contraindication to the measles, mumps, and rubella (MMR) vaccine
- A 16-year-old pregnant adolescent currently at 28 weeks of gestationAdminister the tetanus toxoid, reduced diphtheria toxoid, and acellular pertussis (Tdap) vaccine
Answer
The 2-year-old with sickle cell disease matches with PPSV23 administration; the 11-year-old with complement deficiency matches with MenB vaccine administration; the 6-year-old on chemotherapy matches with the absolute contraindication to the MMR vaccine; and the 16-year-old at 28 weeks gestation matches with Tdap vaccine administration.
Each patient presentation corresponds to a unique deviation or addition to the routine immunization schedule. Sickle cell patients require PPSV23 at age 2 due to functional asplenia. Complement deficiency requires MenB vaccination. Chemotherapy mandates the avoidance of live vaccines like MMR. Pregnancy requires Tdap between 27-36 weeks regardless of prior vaccination history.
