All but one of the 39 congressional districts where at least 60 percent of residents have received a coronavirus shot are represented by Democrats, according to a Harvard University analysis that presents one of the most detailed looks yet at the partisan split behind the nation’s diverging vaccination drive. By contrast, Republicans represent all but two of the 30 districts where fewer than one-third of residents have received a shot... House members representing districts with low vaccination rates and public health experts, discussing their efforts to reach the unvaccinated, described what essentially has become two distinct conversations. One is aimed at chipping away at vaccine hesitancy among conservative white Republicans, while the other is centered around reducing socioeconomic barriers to vaccination for poorer populations and communities of color... “Among the remaining unvaccinated people, white people are much more likely to say they are definitely not going to get the vaccine, whereas Black and Hispanic people are more likely to say they haven't gotten it yet but are hoping to get it soon,” said Liz Hamel, vice president and director of public opinion and survey research at the Kaiser Family Foundation.
