Dr. Ashish Jha: “If there were a place where this could have happened, it should have been Sturgis. The best data suggests that at least 75 percent of the entire South Dakota population has some degree of immunity against the virus: About half of South Dakotans have immunity because they’ve been infected by covid-19, and about half of the population has been vaccinated — some of whom have already had covid-19 when they got their shot, so there is some overlap between these two groups. South Dakota, despite its middling vaccination rates, probably has among the highest levels of population immunity in the nation, driven largely by horrifying winter outbreaks.”
“That’s what makes Sturgis an important test. If it had gone off without big spikes in covid cases, it would have provided strong evidence that this level of population immunity — around 75 percent — would allow us to get back to the way we did things in 2019. But unfortunately, that’s not what happened.”
