The latest screwball COVID-19 proposal is herd immunity achieved by letting nature take its course. Even if possible, it would come at far greater cost in lives and economic consequences than the catastrophe we've already experienced. It's just another irresponsible excuse to do nothing. A vaccine is the only practical way to get there, but we don't have one yet. Parents who are pushing to reopen schools do not understand that the only safe way to do so is to get community spread under control first. Unfortunately, reducing community spread is an uphill battle when there is constant political undermining of the best scientific advice available. While many of us are observing social distancing and mask wearing, others continue to engage in reckless behaviors that feed the pandemic. Taking care of A would also take care of B, but not the other way around.
