Vaccines That Prevent SARS-CoV-2 Transmission May Prevent or Dampen a Spring Wave of COVID-19 Cases and Deaths in 2021
[Pre-print, not peer-reviewed] A model based on King County data shows that if the vaccine efficacy of the Moderna and Pfizer vaccines are primarily driven by complete protection against infection, then prevention of a fourth epidemic wave in Spring 2021 and a reduction of subsequent cases and deaths by 60% is likely to occur, assuming…
