CHICAGO (WLS) -- Since the COVID-19 vaccine began arriving from the DuPage Health Department in December, the DuPage Medical Group has urged their patients to register online to make getting a vaccination appointment easier. "With over 1 million patients and over 150,000 aged 65 and older, we can't hope to call everyone individually," said Dr. Mat Philip, vice president of Innovation for DuPage Medical Group. Philip understands that going online may not be easy for some seniors, so they've added other options to meet patients where they are. "In addition to that, we are mailing them and calling our most at-risk patients to make sure no one falls through the cracks," he explained.
