Ugh... Honestly, I would let your DC make the decision for herself and then tell your H that she has made the decision and your job as parents is to support her. Make sure your DC has all the facts and can present the case herself. However, at 16, the decision should be mostly (if not fully) hers.

Your husband can make the decision for himself, but a 16 year old can weigh the facts and determine what is best for them.

I was on the phone with the hospital and asked DC is they wanted to be vaccinated the next day, they responded with "H@ll Yeah"! I have never seen a teen so excited to get a shot! These kids understand what is at stake.
