Tdap vaccine

Erin

My sisters long term boyfriend (who she lives with) doesn't believe in vaccines (believes they are the governments way of tracking you - he's a conspiracy theorist) and won't get the tdap vaccine. My sister wants to spend a lot of time with her nephew when he's born but I'm worried about her boyfriend not having the vaccine. I'm going to ask my doctor about the consequences with it. Have you guys experienced someone in your family not wanting the vaccine?
