What is Herd Immunity and How long will it take to kick in?
In: Biology
Herd immunity describes how people who are not immune to something can be protected from it when the majority of people around them are immune, making it difficult for a containment to make its way to that person.
In order for it to happen, the majority of people need to be immune, but that is unlikely to happen naturally for a VERY long time. There have only been 6.2 million confirmed cases out of a 7.8 billion world population.
