Yeah, I had a bit of a reaction to my first shingles shot as well but not the second one. It was just that I felt tired later that day (could have been the whisky I had that night too though??)
I don't have any medical insurance as medical stuff is mostly free here in Canada (paid for through taxation so not really free). Dr. visits, hospital stuff including Catscans, MRI's etc operations & hospital stays are all pretty much covered, especially for seniors. For perscription drugs I pay $100.00 the 1st of August each year then I get perscriptions at no charge other than the pharmacy dispening fee, which is $4.00/script.
Flu shots are free, Covid shots are free, the pneumoccal shot was also free. For some reason, the first Shingles shot was free but the second one cost me about $125.00 - not sure why. The RSV shot for some reason is not covered by the Govt.; at least not yet.
