Pneumococcal 13-valent vaccine
pneumococcal disease prophylaxis
"Initial injection hurt slightly, was more than I expected, not like a flu shot.   However, arm only slightly sore next morning and by end of day no issue at all.

Must admit I’ve had allergy shots in the past that were much worse than this, so maybe I was conditioned.   

If it truly prevents or lessen the serious diseases they discuss, then it’s definitely worth any minor inconvenience of the injection.  Recommend."
