Best friends baby isn't going to be vaccinated.

❤️
So my best friend and I had our baby's about two months apart. The only problem, we are raising them COMPLETELY different. She chose not to vaccinate and I did. I'm kind of starting to worry if that's a problem or not. I know none of you are actaully doctors but does anyone have any knowledge that could help me understand if my daughter is at risk or not? Or is her baby at risk from my baby after my daughter gets her vaccines? I'm not too knowledgeable on vaccines, I just know that I want my daughter protected from life threatening illnesses. 
Side note: yes I will speak with my doctor at her next vaccine appointment when my daughter is a year old. Right now I just figured it would be good to hear some different opinions and facts.
