Asking people to get whooping cough booster before they visit new baby

[fromscratch]

I was thinking for those that didn't want to reveal their booster update then I could insist that they wear Dr's masks over their mouths and noses.
HG stands for Hyperemesis Gravidarum Help HER - Hyperemesis Education Research
I'm not fussed if others are not OK with not getting the booster but in light of my GF's 7 week olds death I rekon "no booster, too bad so sad" they'll have to wait till baby is fully immunised which is 6 months if we stick to schedule.
I'm thinking my Baby my rules!

Not unreasonable at all ... if they are parents to a newborn themselves, then the vaccine is free otherwise it is only $40. Thought you might appreciate that info too if you didn't know already
