I should have added that even though he was in close contact (I was pretty well bedridden for a year), my husband did not have shingles.
However, as soon as the new vaccine was available we both took advantage of it. This was before COVID & Co., and we had no reaction (apart from sore arms) to either immunization (two in total, about a month apart.) Having shingles was one of the biggest challenge I've had. It was probably caused by internal stress. There is a short period when you can pass it along to others, but it doesn't last long. Newborn babies and people with autoimmune disorders are at higher risk. I hope you're all doing fairly well. Yours, Lenora
