Thats one nasty illness you was unlucky enough to get, no wonder it takes so long to get better, i hope you can get on top of this terrible health issue ,real soon, and thanks for your well wishes for my Uncle, he's 85 and has got plenty of other health problems to deal with, now its a prostate problem, it never ends.
I have not heard anything about a vacine for shingles over here yet, but if it goes as it does normaly over here, we won't have the option for it for about 5 years after your people have give it the thumbs up, its unreal.
all the best
