The Lynn Community Health Center. (Jesse Costa/WBUR) Lynn is a coronavirus hot spot. Roughly one in six residents has tested positive. So Dr. Elizabeth Quinn was fuming this week as she told frail patients, 75 years and older, that they might have to wait for shots even though hospitals nearby were vaccinating young, back office employees. "Knowing that there is vaccine in our community that could be helping to protect these extremely vulnerable patients but is being used not in that most strategic way is infuriating," says Quinn, who practices family medicine at the Lynn Community Health Center. "And it's demoralizing."
