For immunocompetent individuals, how is pneumococcal vaccination administered if given before age 65?

Pneumococcal vaccination for immunocompetent individuals who receive it before the age of 65 typically follows a specific protocol. Individuals under 65 are recommended to receive one dose of the pneumococcal polysaccharide vaccine (PPSV23). Once they reach the age of 65, they should receive a booster dose. This approach is in accordance with guidelines that aim to maximize immunity as older adults are at a higher risk of pneumococcal disease.

The administration strategy is designed to ensure that individuals maintain adequate protection as they age, particularly as the immune response to vaccines can diminish over time. This is why a booster dose at age 65 is crucial; it helps to re-stimulate the immune system and provide enhanced protection against pneumococcal infections.

Considering the options, the rationale behind one dose followed by a booster at the age of 65 establishes a clear and effective vaccination strategy to safeguard immunocompetent patients throughout their lives.
