People hospitalized with COVID-19 now have one overwhelming thing in common. They're not vaccinated.

In Minnesota, the HealthPartners system has seen a “precipitous decline” in COVID-19 hospitalizations, says Dr. Mark Sannes, an infectious disease physician and senior medical director for the system, which operates nine hospitals and more than 55 clinics. But now, nearly every admitted patient he does see is unvaccinated.

“Less than 1% of our hospitalized COVID patients are vaccinated," he said.
