We have a healthy 66-year-old patient who received a dose of PPSV23 in January then received a dose of PCV15 five months later at a different facility. Should the PCV15 dose be repeated since it was given earlier than the 1-year interval recommended by ACIP?

When PCV15 is given to an adult 65 years or older, PCV15 should be given first followed by PPSV23 one year later (an 8-week minimum interval may be considered for immunocompromised recipients).

What to do when doses of PPSV23 and PCV15 are given without the recommended minimum interval is not addressed in the ACIP recommendations. The CDC subject matter experts have advised that in such a case, the dose given second does not need to be repeated. This is an exception to the usual procedure for a minimum interval violation as described in ACIP’s “General Best Practices Guidelines for Immunization” (see There is no evidence to support that there are benefits to repeating the dose of PCV15.
