Timothy Moore grew up wary of medical treatments in his hometown of Tuskegee, Alabama. His parents had seen what happened to Black people who participated in the unethical Tuskegee syphilis study, where researchers let syphilis progress in Black men without treating them to justify treatment programs for them between 1932 and 1972. So when Covid-19 vaccines became available, Moore and his family didn't rush out to get inoculated. His parents, both born in the 1960s, had only recently been open to getting flu vaccines, Moore said Monday on CNN's "New Day." But one after another, his family began contracting the coronavirus, and so did Moore. He has asthma, a preexisting condition that worsens the risk for severe symptoms from Covid-19.
