Hi - The recommendation for pneumonia vaccines varies depending on your age and the previous vaccine you had. After 4 years, my primary recommended a repeat for me, with a newer vaccine that covered several additional strains.
That said, if I were you I would check my records and see which one I had, then discuss timing for the new vaccine with my primary.

This is just anecdotal or incidental evidence, but we are vaccinated and were closely exposed to grandkids with RSV twice this winter - neither time did we catch it, but my unvaccinated daughter and her husband did. We also flew (masked) in the height of the holiday travel season.
