With 25 million confirmed cases and over 150,000 new cases per day, the United States will have more than 50 million inhabitants with resistance to the virus due to past exposure.

The US has vaccinated 20 million people in under four weeks, and at the present rate of six million vaccinations per week, an additional 170 million Americans will be resistant by the end of the second quarter of this year.
By that projection, 220 million of America’s 330 million inhabitants, or two-thirds of the total, will be resistant, and America will achieve herd immunity.
Virologists believe that “herd immunity” will be achieved when somewhere between 43% and 60% of the population becomes resistant to COVID-19.
