Vaccines

Need some info because I don’t know enough on the issue. Ok so my daughter just turned 2, and I get all of her vaccines, she is all caught up. My husband has a child from another girl from before me, she is 8. Never came across my mind about the vaccines, but the mother just made a post on fb about how she is against the vaccinations. So now I’m wondering if my daughter is in jeopardy every time we pick up his other child, or is my daughter ok because she’s got her shots??? Any advice would be helpful, thank you.
