Coronavirus herd immunity possible in this state by July, health official says

At least one midwestern state could see herd immunity by this summer, according to a health official there. 

To date, about 13% of Wisconsin residents are considered fully vaccinated, while an estimated 23% have received at least one dose.  Vaccine eligibility expanded in the state on Monday, with those ages 16 to 64 with certain underlying medical conditions now able to get the vaccine. However, state health officials, in line with a directive from President Joe Biden, expect to make all residents ages 16 and older eligible by May 1, regardless if they have an underlying health condition or not.
