(Combined Sources) State health officials say flu vaccinations will be required for all students 6 months or older who attend child care, pre-school, school and college in Massachusetts to reduce the possibility of a double whammy of respiratory illnesses during the ongoing coronavirus pandemic. The state Department of Public Health said Wednesday that students must get the influenza vaccine by Dec. 31. There are exemptions, including for medical and religious reasons, as well as for homeschooled children and higher education students who are completely off-campus and engaged in remote learning only.
