Editorial: By the numbers

COVID-19 will be done for when our population has herd immunity, defined by Oxford Dictionary as “resistance to the spread of an infectious disease within a population that is based on pre-existing immunity of a high proportion of individuals.”

With herd immunity, so many people have had the disease, or been vaccinated against it, that the virus cannot find pathways to continue to spread.

There are two ways to get to herd immunity. The most attractive is through a vaccination, so that people get protection without getting the disease.

Far less attractive is the philosophy to let the virus spread unchecked through the population. Eventually it will die out because so many people have had it. Unfortunately, a lot of people would have to die first.

Herd immunity, according to various sources on the internet, is 70 percent of the population or better. Vaccines are on the horizon. It will require tens of millions of doses to start on the vaccination road to herd immunity.
