Visitors vaccines

I just need to vent on this and I know you'll agree.
So nicu told me that anyone who visitsmy daughter while she's there should have the dtap and flu.  My father in law doesn't have a the flu, and apparently the Pharmacy they go to doesn't have it- so they told my husband & I we need to find out where he can get it.  Tell me how that is my bleeping problem?  And why either of us should have to deal with that when I'm in the hospital.  I'm currently on bedrest at the hospital for the next week or so until I deliver I was admitted a week ago due to my preeclampsia being so severe they were afraid I was going to have a seizure.  I was diagnosised with preeclampsia at ~25 weeks, I'm 32 weeks plus days today.  Like tell me I'm wrong here?  Because I'm not having anyone visit even when she's home without vaccines.
