Centers for Disease Control and Prevention Director Rochelle Walensky on Tuesday expanded eligibility for a second COVID-19 booster shot to all Americans age 50 or older in addition to some with compromised immune systems, the agency announced in a statement.
Driving the news: "This is especially important for those 65 and older and those 50 and older with underlying medical conditions that increase their risk for severe disease from COVID-19 as they are the most likely to benefit from receiving an additional booster dose at this time," Walensky said.
