This small window of opportunity means that for it to be most effective, we need accurate, rapid tests for diagnosing COVID, and an acceptance of contact tracing. I suspect solutions to the former will come in the relatively near future, while the latter will be more problematic. Still, one thing that might sway contact tracing skeptics is that some researchers believe that administering the pill to asymptomatic people who have been in contact with someone diagnosed with COVID may be functionally similar to getting vaccinated.
