  • Achieving herd immunity to SARS-CoV-2 without overwhelming hospital capacity was found to be impractical in a modeling study, due to the need to change social distancing requirements over time and with little room for error. Suppression of SARS-CoV-2 transmission was possible with realistic levels of social distancing over several months. The transmission model was parameterized to the UK.
