As the weather begins its annual cooldown, it will cause more people to head back inside, whether at home or in some form of congregation. Even though there are vaccines and now boosters out there, one can never be too cautious when it comes to COVID-19, according to Dr. Thomas File, infectious disease expert at Summa Health. Dr. File joined the Ray Horner Morning Show to talk about the surges of COVID-19 that have popped up, from the original alpha variant to this summer's and early fall's delta. He also touched on the possibility of more variants on the horizon, as well as the thought of mixing the vaccine boosters.
