The problem with herd immunity to this virus is how short the immunity to corona virus is - around a year. If we wait for herd immunity to build from low level natural spread then we will never get there.

There is a very major risk with extrapolating the Santa Clara data in the motivation of those being tested has not been controlled. Who is more likely to want to know they have been infected - those who have had classic COVID-19 symptoms or those who haven’t.

Source? Right now, that seems unknown - too soon to tell. A few months of measuring antibody levels and we'll know more.

This is what we know from other human corona viruses. SARS-CoV-2 could be different, but without evidence I would not want to bet on long immunity.
