Types of Pneumococcal Vaccines
There are two main types of vaccines: PPSV and PCV. PPSV contains polysaccharides from 23 serotypes and is effective in adults. PCV includes capsular polysaccharides linked to proteins, enhancing immune response and offering herd immunity.
Who Should Get Vaccinated?
The CDC recommends pneumococcal vaccines for adults 65 and older, and those 19-64 with certain health conditions. Conditions include chronic diseases, risk of meningitis, and weakened immune systems.

Approach to Vaccination
For most adults, PCV20 is preferred due to its simplicity. If unavailable, PCV15 followed by PPSV23 is an alternative. For high-risk individuals, PCV20 and PPSV23 are recommended to cover more serotypes.
