98 New Milford Public School District staff members were absent on Monday, roughly 21 percent of their total staff. According to an email Tuesday night from Superintendent Alisha DiCorpo this was likely due to after-effects of a second dose of the COVID vaccine administered over the weekend. The CDC has found that side effects can be more intense than the ones experienced after the first shot. Symptoms can include fever, nausea, headache, chills, and tiredness. New Milford was able to pull together substitute staffing to keep the schools open on Monday, noting that not all staff absences were classroom teachers.
