I’ve not had issues getting the pneumococcal vaccine, however tetanus shot did give me with an eye twitch and some extra uncontrolled muscle movements in my hands for about a year afterwards. Mostly I try to be practical when it comes to vaccines, if the potential for catching disease is high, and disease is greater suffering than the vaccine side-effects, then I get the vaccine. I skip the flu shot, as my risk group even with MS is lower than potential side-effects. Pneumococcal however I’m at a higher risk due to both the MS and scarring on the bronchial tubes with additional risk from chronic sinusitis. All roads pretty much run straight towards pneumonia for me and nearly died from it twice before the vaccine came out. Not willing to risk a third time.
