For patients with chronic renal failure, vaccination against pneumococcus usually includes both PCV13 and PPSV23.

• A. Both PCV13 and PPSV23 are recommended for patients with chronic renal failure.
• B. PCV13 is recommended but PPSV23 is not.
• C. PPSV23 is recommended but PCV13 is not.
• D. Neither PCV13 nor PPSV23 are recommended.

Answer: (A)

Chronic kidney disease blunts immune responses, so protecting with a strategy that combines strong immune priming with broad serotype coverage is best. The pneumococcal conjugate vaccine (PCV13) is a conjugate vaccine that induces a robust, T-cell–dependent immune response and creates immunologic memory, which is especially important in patients with renal failure who may not respond as well to vaccines. The pneumococcal polysaccharide vaccine (PPSV23) covers additional serotypes not included in PCV13, broadening protection. Giving PCV13 first primes the immune system, and then PPSV23 is given after an interval to extend serotype coverage. This sequential approach provides the most comprehensive protection for patients with chronic renal failure, which is why both vaccines are recommended.
