flu shots

i recently shared with my family and his my fiancé's family that we've decided that since our daughter will be born in the middle of flu season (end of february) that we're asking them to please get the flu shot before coming to visit our daughter when she's born, and that if they don't wish to get the flu shot that's fine but if they don't they will need to wait until after flu season is done to come visit our daughter and we're receiving a lot of comments like "you can't keep us from her", "she's our family we will come see her when we feel like it" and "i don't get the flu shot and i'll be coming to see her whether you like it or not"....we're only trying to do what's best for the health and safety of our daughter especially since she won't be immunized to anything until she's 2 months...just wondering if anyone has any advice on what to do to not start a bunch of family drama

thank you 😅😅
