Which adults should get one of the new pneumococcal vaccines, Prevnar 20 or 15-valent Vaxneuvance, and when?
These products are conjugate vaccines like Prevnar 13...but cover more strains of the bacteria that cause pneumococcal disease.
And they may provide longer-lasting and better immunity than Pneumovax 23, which is a polysaccharide vaccine.
This is leading to changes in pneumococcal guidelines for adults 65 and up...or 19 to 64 with risk factors (cancer, diabetes, smoking, etc).
For example, an eligible adult with no prior pneumococcal vaccine should receive Prevnar 20 alone...or Vaxneuvance PLUS Pneumovax 23, usually after 1 year.
Anticipate that the choice may boil down to what's on formulary...CDC guidelines don't suggest one approach over another.
Be aware, eligible adults who previously only had Pneumovax 23 may get either Prevnar 20 or Vaxneuvance alone...after a year.
But don't expect to dispense Prevnar 20 or Vaxneuvance for adults who got Prevnar 13. There aren't data on whether it adds much benefit.
