According to guidelines, adults 65 or older should receive how many pneumococcal vaccines?

• A. One
• B. Two
• C. Three
• D. None

Answer: (B)

Older adults should receive both pneumococcal vaccines to achieve broad protection. The conjugate vaccine PCV13 introduces the immune system to key serotypes and primes a strong response, while the polysaccharide vaccine PPSV23 adds coverage for additional serotypes not included in PCV13. Using both vaccines in sequence expands protection beyond what either vaccine alone can provide. The typical approach is to give PCV13 first and then PPSV23 after an appropriate interval. If one vaccine has already been given, the other is still recommended when appropriate to maximize protection.
