As the COVID-19 pandemic has dragged on into its fourth month, public health officials are not optimistic that populations will be able to build up a functioning “herd immunity” to the disease before a vaccine is developed — something that could still be several months away.

The idea of herd immunity is based on the concept that, if a large enough percentage of a population becomes immune to a certain disease, it will break the chain of transmission, make the disease less likely to spread and, at a certain point, the immunity of the group will protect even those who aren’t immune.
