People in the uk, don't shoot me. Instead, lobby the nhs to cover the Shingrix vaccine which is over 90% effective, and much more effective in older people than Zostavax. Also because it is not a live vaccine it is more appropriate for people on immune suppressing medication. If in the US you can only get Shingrix. In Canada both are available. Opt for Shingrix.
I had my first Shingrix vaccination yesterday. I was actually very worried about side effects. Well. A few hours after getting it I felt really fatigued. You all know what that's like. Sensing it was only going to get worse, although it was still quite early in the evening I got ready for bed. Ended up sleeping all evening as the thought of reading or even watching tv was too much for me. I woke in the morning with pains no worse than a minor PMR flare, which have been improving all day. (I'm currently on 5.5 mg pred, tapering at medium speed from a severe flare earlier in the year.)
I did find I was very thirsty yesterday, and also regretted the rather large supper I'd had, but wasn't sick or anything. Just got comfy in an easy chair and nodded off until it was time to go to bed properly.
