puemonococal vaccine?

Hi all, Hope you’re all ok. Question.. my MS nurse has asked me to have the puemonococal vaccine before I have my infusion, however has mentioned it’s only advisory and not something mandatory to prevent me having the infusion. Just wondered if some of you have had this, and is it better to do so? I’m very sceptical about vaccines as especially with the covid vaccine I am certain that this brought out the MS I have today.. despite many professionals saying they couldn’t comment on it, it’s just my own view on what is now an unpredictable life changer. Look forward to hearing from you all. Thanks Ayrton
