The writer makes the useful point that we must unwind from our response to Covid-19 soon, especially our reliance on social distancing. Public immunity testing is increasingly discussed as a viable approach.
Personally, I wouldn’t mind having to pass a test prior to entering a restaurant, workplace or hotel, but I suspect that testing at that level may not become necessary as strong therapeutic treatments (e.g., hydroxychloroquine) become more widespread. I would, however, oppose government issue of “immunity cards.”
It occurs to me, too, that immunity to SARS-Cov-2, may be more common that we have imagined. I’d be interested to hear a scientific opinion on levels of immunity that would be sufficient to allow the relaxation of social distancing guidelines.
