"It is heart-wrenching to see unvaccinated individuals come into the hospital with regret," said Dare, an infectious diseases physician. They are patients who, "if they could do it all over again, would have had the vaccine in a second." Arkansas has one of the lowest vaccination rates in the country, with less than 35 percent of adults having been fully vaccinated. Now, the state's low vaccine uptake has crashed headlong into the highly contagious delta variant of the coronavirus, leaving some hospital systems once again teetering on the brink of collapse more than a year into the pandemic... "It's just a mess," said Dr. Mayrol Juarez, a critical care physician at the hospital. "Everybody in the hospital is doing extra shifts, calling out for other hospitals to help." Juarez said many of his hospitalized Covid-19 patients are "shocked" that Covid-19 truly exists and that it can make people very sick and even kill them. "A comment they make all the time is that they wish that they knew they were going to end up in the hospital this sick and they would have made a different choice and got the vaccine," he said.
