Boyfriend being a little b*tch

I am due in about 4 weeks and I told him that everyone will be getting the flu/whooping cough shot before they come and see the baby! He will not get it because of all the things he read about it and it's dangerous...I told him your not doing it for you its for out baby protecting him.. Can anyone help me talk him into getting the shots or info to give him on how important it is to get them... We had a little baby girl die from the whooping cough not long ago and it scares me that he is being so selfish that he won't even protect his own son
