For a disease to be prevented from spreading, you need a certain percentage of people to be immune. It's different from disease to disease and also depends on the vaccine itself. Some diseases like Covid can still be spread to people who are vaccinated (though obviously the worst of the symptoms are mitigated).
For the sake of example, let's say you need 90% immunity for a disease to not spread. Maybe 5% of the population cannot be vaccinated due to immune conditions, being too young, etc. That gives 5% of wiggle room.
Then there are acolytes of the fraudster, Andrew Wakefield, who faked data to get a flashy headline to get published in a prestigious journal. That includes RFK jr., Jenny Mccarthy, mayim bialik, etc. Clinging to their views for so long makes them unable to change them even if you show them proof that they are wrong. That might be another 1% of people.
There are a very small percentage of people who shun vaccines for lets say "true" religious reasons. Most of the people who try to claim religious reasoning for refusing vaccines are members of religions that are completely fine with vaccines. They are usually just really stupid people who are scared of needles and/or don't think it's that big of a deal with modern medicine. That's probably another 1% of people.
Then there are people that are homeless or otherwise outside of the system. Vaccines are one of the most cost effective methods to improve health of a country, so despite the nightmare that is our healthcare system, you typically should never have to pay for a vaccine. It may be a bit more work than someone who is homeless and/or has substance abuse or mental health problems can prioritize. That might be another 1%.
All together, that would put us at 92%, above the threshold for a widespread epidemic, but all of those categories of people who don't get vaccinated tend to be in communities, and so we can have outbreaks in those communities.
