If someone doesn't want to vaccinate their kids they are risking the lives of many other people in their community with this choice, not just the kids they decide not to vaccinate.
The problem is that infants can't be vaccinated for things like measles until they are 6 months old.
So people who aren't vaccinating their kids and have their kids running around spreading the measles virus in public places are risking the lives of any infants under 6 months of age who haven't even had a chance to be vaccinated.

It’s not limited to infants btw. People with immune deficiencies can’t be vaccinated either and for some people the vaccine doesn’t work. They’re all protected by herd immunity and if the vaccination rate falls below the critical threshold they’re all at risk.
