Study Shows Decline in COVID-19 Vaccines Over Time, Need for Booster Shots

Farshad (Dr. Shad) Fani Marvasti, MD, MPH, director of Public Health, Prevention and Health Promotion at the college, says those with chronic illness, as well as those in jobs that often deal with face-to-face communication, should consider getting a booster shot as soon as possible.
