A Wall Street Journal analysis shows sharp geographic divides in vaccination and hospitalization levels, with every state that has an above-average vaccine rate showing below-average hospitalizations, including in well-vaccinated New England. In the South, meanwhile, fewer people are vaccinated on average and hospitalization rates are climbing faster…

Even though vaccinated people can catch and in some cases spread Covid-19, data suggest vaccines provide protection against infection and transmission. In Santa Clara County, Calif., the recent seven-day average of daily cases among vaccinated people was roughly 6.8 per 100,000 people on Aug. 4; the case rate among the unvaccinated was nearly four times higher.

Data from about half of states on Covid-19 infections among vaccinated people, collected by the Kaiser Family Foundation, found that less than 1% of fully vaccinated people have reported experiencing a breakthrough infection in 2021.
