I was out at Warwick Castle yesterday with my DH who has an autoimmune condition so subsequently a compromised immune system. He has also never had chicken pox. It was a lovely day but incredibly busy and crowded in confined places. Throughout the day we came into close contact with 3 families where one of their children were covered in unscabbed chicken pox so still contagious. DH has today had to go to his GP who has given him the chicken pox vaccine to be on the safe side (but this is not without risks for him and has still made him feel really rough for the rest of the day) Clearly I think this is downright selfish but there must be otherwise pleasant families out there who don't think this. AIBU to ask why you not inconveniencing yourself by cancelling a family trip is more important than protecting more vulnerable members if the public?
