Vaccines

Anyone else really paranoid about people coming around your baby at such an early age? My husband is in the Navy so we aren’t close to home, and our closest relatives are like 10 hrs away, but they wanted to be here for the birth. She my closest cousin, so I felt really bad telling her we’d like to be alone during his birth and for the first few weeks because he’ll be so little and he could get sick with so many people around. (She has 5 kids and none of them get vaccinated). I have a 12 year old who’s up to date on all her shots, so I don’t care when they come around her, because she’s older and her immune system is really good, but I even took her in the other day to make sure she was up to date on everything. Short back story, August 2018, I had a baby girl. We was stillborn, which is making my anxiety even worse now, but I guess I just wanted some opinions. Am I wrong for feeling this way?
