Omer et al. describe methods for estimating the herd immunity threshold and estimate a SARS-CoV-2 herd immunity threshold of 50-67%. Because most, if not all of the population lacks immunity to the novel SARS-CoV-2 virus, they estimate that around 198 million people in the US would have to be infected to reach a herd immunity threshold of 60%, which would result in several hundred thousand additional deaths using an estimated infection fatality rate of 0.5%. The authors highlight the importance of efficient and widespread vaccination campaigns to reach the herd immunity threshold.<span class=\"Apple-converted-space\">\u00a0<\/span><\/p>\n<p><i>Omer et al.
