Vaccination isnt 100% effective. When people talk about herd immunity, the "free riders" it tolerates should be are those that were vaccinated yet it didn't take. If one of them gets sick, the disease wont be able to transmit to the others because of those that are immune. Adding other non-vaccinated people to the mix increases the odds that these vaccinated-but-vulnerable people will be at risk as the disease is able to find enough transmission to stay viable. |
