I haven't gotten any vaccines, including a flu shot, in many, many years - so that adds to my apprehension.
Yes, getting Shingles at age 13 was really bizarre, and back then there was no treatment. At least it got me out of final exams, lol. The second time was during chemo, and I recognized and diagnosed it immediately - it was in the exact same location. I called my doctor and since I caught it so early he was able to send in a prescription.
