If a 70-year-old female is inquiring about pneumococcal vaccination after having received PPSV23, what should you recommend?

The recommendation of PCV20 for a 70-year-old female who has previously received PPSV23 aligns well with the current guidelines for pneumococcal vaccination in older adults. After receiving PPSV23, the CDC recommends that adults aged 65 years and older should receive a dose of either PCV13 or PCV20 if they have not already been vaccinated with a pneumococcal conjugate vaccine.

PCV20 is the most recent pneumococcal conjugate vaccine and covers all the serotypes included in PCV13, as well as additional serotypes that have been identified to cause significant disease. Therefore, for someone who is 70 years old and already received PPSV23, administering PCV20 would provide broader coverage and enhance protection against pneumococcal disease.

Options such as PCV15 and PCV13 may not provide the same breadth of coverage as PCV20, particularly for an individual who has already received PPSV23, which is why they would not be as optimal for this patient scenario. Similarly, recommending a repeat dose of PPSV23 is generally not indicated for those who have already received it, given the existing vaccination guidelines and the intent to utilize conjugate vaccines for my optimal protection.
