Accepted Answer

Herd immunity is achieved when a large proportion of a population becomes immune to a disease, and this can be achieved through vaccinations. When a significant number of people within a population are vaccinated against a disease, the likelihood of transmission of that disease decreases, thereby protecting unvaccinated individuals as well. This is because the vaccinated people are less likely to get infected and therefore less likely to spread the infection.
