What do you mean by “Herd Immunity”?

Herd Immunity or Community Immunity has been touted as the thing that will end the pandemic. But, with several populations reaching the herd immunity threshold, why are we still in this mess?

According to the Gospel of Luke, Jesus was asked about loving one’s neighbor with a simple question, “Who is my neighbor?” Jesus answered with the parable of the Good Samaritan. It’s a good parable, even when you strip away all the religious context, it is a story that can teach us a lot about how we deal with people who are not like us and are in trouble. It answers the question by basically telling us that our neighbors are anyone we come across, from any walk of life, who need our help.

The parable speaks of a man who is on his way to Jericho, gets attacked and robbed, and is left for dead. A couple of people go by and see the man — one of them being a priest — and ignore or avoid the man. Another man, a Samaritan, stops and renders aid to the man, taking the man to an inn and paying for the man to stay there while he recovers. This is how we now arrive at the concept of a “Good Samaritan,” someone willing to render aid without being asked and without obligation to do so.
