Very definitely - go for one. I had to wait until I was 70 years old but i would have had one earlier If i had been eligible. Reason? I caught Shingles when I was 68 and, despite anti-virals, which were prescribed towards the end of the window where they do some good, I was terribly ill. At least 6 weeks and then a long haul back.
I had Shingles again this year --- much, much milder. I felt poorly and had pain from the affected area but it was bearable and I recovered much more quickly.
Don't hesitate is my advice.
