Most experts would agree that it is not an option to let the virus infect a community and hope that people in that community would then have antibodies protecting them against the coronavirus.
Health experts worldwide are not sure how long immunity does last and that the only real choice that nations (and tribal communities) face is to work to break transmission chains.
That is until an effective vaccine is found.
One of the questions being asked is whether a natural immunity to the virus occurs (especially in a person who has had it) and how strong it may be compared to a good vaccine.
After the first wave of infections in Europe, in March and April of this year, scientists at Imperial College in London have tracked antibody levels in the population.
What they found was that what is called antibody prevalence fell from June to September and what that signaled is that there may be decreasing population immunity and decisions were made to enforce new lockdowns as they face a second wave of infections.
This goes against what those who have been infected and have recovered are hoping, that there is protection after an infection and that is long lasting.
