Do you think 20% exposure (at a cost of 17.5k lives) buys you herd immunity?
Even in hotspots like New York City that have been hit hardest by the pandemic, initial studies suggest that perhaps 15-21%6,7 of people have been exposed so far. In getting to that level of exposure, more than 17,500 of the 8.4 million people in New York City (about 1 in every 500 New Yorkers) have died [...] To reach herd immunity for COVID-19, likely 70% or more of the population would need to be immune. https://coronavirus.jhu.edu/from-our-experts/early-herd-immu...
