Covid Wedding

Hi yall

I was just wondering if i could get opinions on a situation im in?

My sister is having her wedding in october of this year and her stag and doe is in august. She has high risk people attending and is requiring people to have a least one vaccine shot. My plan for the vaccine was to wait until more information to come out surrounding the vaccine while still maintaining all covid regulations (social distancing, masks, hand washing, reduced traveling etc). I figured that this was the best move for myself because of the lack of information on long term symptoms and just general misinformation being spread around.

I want to tell her and keep her in the loop and see if we could have a get together post wedding? We havent seen each other since last winter as well due to all of this. I want to be by her side but at the same time, i don't want to get hurt but also dont want to put others at risk.

Edit: I not shaming anyone who gets the vaccine. High risk people should definitely get it, im not arguing that at all.
