Well the measles vaccine (93-97%) and polio vaccin

Well the measles vaccine (93-97%) and polio vaccine (90%) were not 100% either. However, if you get 95% efficacy, then the herd immunity will wipe out covid. The question is whether the mRNA vaccines are 95% effective. Or was it just that those 95% did not come in contact with anyone with covid to get it?
