Dom, 100% vaccination has never been achieved or needed for any disease, even smallpox. Polio, for example, ended when pesticides stopped being sprayed on children. The vaccines were only marginally effective. It's not true that "vaccines are only effective when a large percent of the population is vaccinated." Vaccines serve to protect the people who take them. If they're not doing that, it's not the fault of the unvaccinated. Finally, no sane person thinks we can"eradicate" COVID. It's all over the world, most of which is not receiving vaccines at all.
