Easy-to-read guidelines are available on the Maine CDC and US CDC websites:
In addition, US CDC has developed a fact sheet that addresses common questions about pneumococcal vaccination for adults, including the difference between PCV13 and PPSV23 vaccines:
- PCV13 (pneumococcal conjugate vaccine) protects against 13 of the approximately 90 types of pneumococcal bacteria that can cause pneumococcal disease, including pneumonia, meningitis, and bacteremia.
- PPSV23 (pneumococcal polysaccharide vaccine)protects against 23 types of pneumococcal bacteria. This vaccine helps prevent invasive infections like meningitis and bacteremia, but only offers low levels of protection against pneumonia.
