- We believe COVID-19 herd immunity (>60% of population immune) will be reached in the US by late summer/early fall 2021 (Sep-Nov 2021).
- At the time herd immunity is reached, roughly half of the immunity will be achieved via natural infection, and the other half will be achieved via vaccination.
- New COVID-19 infections may become negligible before herd immunity is reached. Our current best estimate of when daily community transmissions will drop below 1,000 per day is summer 2021 (Jul-Sep 2021).
- Summarizing the above findings, our best estimate of a complete “return to normal” in the US is late summer 2021 (Aug-Oct 2021).
- We estimate around 30% of the US population (~100 million) will have been infected by the SARS-CoV-2 virus by the end of 2021. This translates to a final US COVID-19 death toll of roughly 500,000 (+/-100k) reported deaths.
