Should an 80-year-old patient who was given PPSV23 at age 65 years be revaccinated with PPSV23?

No. ACIP does not recommend revaccination with PPSV23 for any adult who has received a dose of PPSV23 after turning 65. The patient may, however, receive either PCV15 or PCV20 if they have not already received PCV13.
