Dr. Lisa Costello, a WVU Medicine pediatrician and assistant professor at the School of Medicine, is encouraging everyone to get a flu shot this season. National Influenza Vaccination Week is Dec. 7-13, and Costello says it’s the perfect time to arm yourself against the flu. She talks with Inside WVU today host April Kaull about why children and the elderly are particularly vulnerable, whether the vaccine mist is as effective as the shot, and dispels some vaccine concerns.
