New Fairfield plans to wind down the municipal vaccine clinic.  After 10 weeks, with increased availability elsewhere, the town will close up by the middle of next month.  New Fairfield administered 3,00 doses as of Thursday afternoon.  Volunteers have found when calling people on the waitlist, they've already been vaccinated elsewhere.  Despite a sharp drop in Johnson & Johnson doses due to a production issue, Connecticut public health officials still expect supply to outpace demand by the end of the month.  According to the latest state report, at least 42 percent of New Fairfield residents had received at least one dose of a COVID vaccine.
