In countries where no significant proportion of the population is vaccinated, there is a huge risk of sustained community spread of COVID-19 over a prolonged period. The mutated variants from the unvaccinated population will be able to infect even those in the vaccinated population. With the interconnectedness of countries and regions around the world, no single population lives in total seclusion. It won’t be realistic for countries that have vaccinated their populations to close their borders against countries that haven’t vaccinated. Unless vaccinated countries completely shut their borders from the rest of the world, there would always be some interaction between their citizens and citizens from unvaccinated countries.
