An examination of city and federal vaccination data and interviews with more than 20 researchers, doctors, health officials and residents in the nation’s sixth-largest city opens a window onto the missteps and misunderstandings, the legacy and loss that have fostered the disproportionate pain of death and disease in communities of color. Coronavirus immunizations are the latest iteration of the pandemic’s unequal burden. The city of Philadelphia is the nation’s largest predominantly Black county, and it has one of the higher vaccination rates among counties with a preponderance of Black residents. But that doesn’t mean Black people are getting vaccinated at a high rate. The city’s data shows that while 52 percent of White people have received at least one dose of a vaccine, just 34 percent of Black people have. Nationally, 54 percent of the population has received at least one dose. “I get mad when I see the numbers,” said Ala Stanford, a surgeon and founder of the Black Doctors Covid-19 Consortium, whose organization, according to the group’s figures, had administered nearly 50,000 vaccinations as of June 11, about 75 percent of which went to African Americans. It’s like the city “just decided we are everybody Black in Philly’s answer,” Stanford said recently, pausing a phone interview to encourage — and then schedule — the custodian emptying the trash in her office to get vaccinated at the end of his shift. “It just can’t be me. What are the rest of y’all doing?”
