Many of these states are located in the Northeast with Vermont leading the nation with over 86% of its adult residents receiving one shot, according to the health data.A dozen states, almost all located in the South, haven’t cracked the 60% mark for their adult residents with one shot, CDC data showed. Mississippi has the lowest percentage of adults with one shot, at 50%, according to the data.Coronavirus cases and hospitalizations in the country have been on the rise, particularly in locations with low vaccination numbers, health officials said.Officials in several states, including Mississippi, Alabama, Missouri and Arkansas, are reporting that the majority of their hospitalized patients are unvaccinated people.The U.S. began vaccinating residents in December, starting with health care workers and the elderly. By mid-April, all residents above 18 were eligible and a month later, the Pfizer vaccine was approved for Americans over the age of 12.Two of the three approved vaccines, Pfizer and Moderna, require two doses and use mRNA technology to protect against the virus. The Johnson & Johnson vaccine requires only one dose.The seven-day average of new daily first shots administered peaked at 3.4 million on April 11 but it has declined to low of 217,884 on July 7, the CDC reported. Several states that had lagging vaccination numbers, however, saw a small jump in shots administered during the final weeks of July.The seven-day average of first doses administered grew to 367,351 on July 27, the CDC data showed.On Sunday, White House COVID-19 data director Cyrus Shahpar revealed that over 517,000 people received their first shot.Anyone who needs help scheduling a free vaccine appointment can log onto vaccines.gov.Copyright © 2021, ABC Audio.
