Pneumococcal Vaccine in Adults: A Quick NP Guide

A 66-year-old comes in for a physical and you're trying to remember which pneumococcal vaccine to give, and whether their old PPSV23 counts. This is one of the more confusing vaccine schedules. Here's how to keep it simple in clinic.

Who needs pneumococcal vaccination

• All adults 65 and older, regardless of health status.
• Adults 19 to 64 with risk factors, including:
  • Immunocompromised (HIV, cancer therapy, transplant, asplenia).
  • Chronic conditions (diabetes, heart disease, chronic lung disease, liver disease).
  • Smokers and heavy alcohol use.

Vaccine options and schedules

PCV20 (Prevnar 20)

• Single dose, no further pneumococcal vaccines needed.
• Easy, one-and-done option for most patients.

PCV15 (Prevnar 15)

• If given, it must be followed by PPSV23 (Pneumovax 23) at least 1 year later (minimum 8 weeks if immunocompromised).

PPSV23 alone?

• No longer recommended as the sole vaccine in adults. Always use PCV first if you're starting new.

For most adults, PCV20 is the simplest path, especially in primary care. PCV15 plus PPSV23 is still an option if your clinic or insurance formulary requires it.

Revaccination rules

• If a patient already had PPSV23 before 65, give another dose at 65 or older (at least 5 years after the last one).
• If they've already had PCV13 in the past, treat it as though they had PCV15: still give PPSV23 if indicated.

A practical workflow

1. Ask age and risk factors at wellness visits.
2. Choose PCV20 if available, the simplest pathway.
3. Document clearly which product and date.
4. Educate patients: one vaccine now can prevent a life-threatening infection later.

The short version

• All adults 65 and older need pneumococcal vaccination.
• High-risk adults 19 to 64 should be vaccinated too.
• PCV20 is the simplest choice for most adults.
• Don't forget the timing rules if a patient already had a prior vaccine.

Frequently asked questions

What if I can't remember whether they had PCV13?
If the record is unclear and you can't confirm prior doses, treat the patient as unvaccinated and follow the current schedule. Document what you used and the date so the next visit is cleaner.

Can PCV and a flu shot go in the same visit?
Yes. Pneumococcal vaccines can be given at the same visit as other vaccines, in a different injection site. Same-day vaccination is a good way to catch patients up.

Why not just give PPSV23 like we used to?
PPSV23 alone is no longer recommended as the sole vaccine in adults. A PCV product (PCV20, or PCV15 followed by PPSV23) gives broader, more durable protection.
