As more and more people receive COVID-19 vaccinations, the term "herd immunity" is being tossed around once again as the solution to the devastating virus ravaging countries all over the globe since December, 2019.
The term explains the situation in which a high percentage of people in a given community (a city, state or entire country) is immune to a disease, either through vaccination or because those people have been exposed to the virus and their immune systems have built antibodies to protect them from it.
People who tout it as the best defense against SARS-CoV-2, the virus that causes COVID-19, are correct in their thinking -- herd immunity is the best way to prevent contagious diseases from circulating throughout a population because it slows down or eliminates the spread of the virus from person to person.
