The Foxborough Board of Health will hold a free flu clinic on Nov. 14 for residents ages 3 and older. Inoculations are available by appointment only, by calling 508-543-1207. Those receiving shots must bring an insurance card. Required forms are available on the town’s website at www.foxboroughma.gov. Or, when calling for an appointment, participants may request that one be e-mailed to them. Those without insurance coverage are still eligible for a shot, officials said.
