Opinions

Ok ladies i need some opinions im a FTM and just got the whooping cough vaccine yest. The dr also recommended that ppl who will be around the baby often should also get it so my parents and hubby will also be getting it since the baby cant get it until atleast 2 months. However my hubbys aunt is going to be visiting shortly after the baby is here for a few days (not sure how long after baby is born or for how long she'll be staying) should we mention to her about getting the vaccine or will she be ok with just using hand sanitizer? I havent thought about this until i got the shot myself.. i know some ppl dont get it and they are perfectly fine..
