> Well I agree and understand that herd immunity exists and it protects the small number of kids who can’t get the vaccine for whatever reason.

You need to understand that herd immunization actually helps everyone, not just some small number of children who can't get vaccinated, because even the best vaccines don't offer 100% protection.

Your odds of getting sick are based on the odds that other people around you are contagious. That much should be extremely obvious, because every encounter with a contagion rolls the dice again.

What's less obvious is how much that matters because math is hard. Even if you have 95% immunity to some infectious disease, your probability of getting it at least once after 10 exposures is a whopping 40% (1 - 0.95^10). Everyone's protection, yours included, comes from reducing your chances of being unwittingly exposed because the people around you aren't getting sick, and that means vaccinating them too. When one person gets sick, everyone around them is put at increased risk. The way you fix that for everyone is by making it less likely that any member of the herd gets sick from any given exposure.
