My patient just turned 50 and had a dose of PPSV23 at age 47 due to alcoholism. What is due now?

CDC recommends that adults who have ever had at least one dose of PPSV23 do not need another dose of PPSV23. They should receive one dose of any of the 3 recommended vaccine options: PCV15, PCV20, or PCV21, at least one year after their PPSV23 dose.
