A key state health department leader is hedging on whether Wisconsin can attain COVID-19 herd immunity by mid-2021.
Department of Health Services Deputy Secretary Julie Willems Van Dijk has previously said that 70% of Wisconsin's population would need to be vaccinated to attain herd immunity and the state could reach that benchmark by July.
But vaccination rates have slowed dramatically and are now growing at only about 1% a week.
Willems Van Dijk says it's still possible Wisconsin reaches the 70% mark by July if vaccination rates increase, but right now it appears the state won't get there until September or October.
