BIDDEFORD (WGAN)- Walk in appointments for the Johnson and Johnson vaccine will be accepted for all people 18 and over at Biddeford High School today until 3:30. CBS 13 reports that this announcement comes two days after US health officials lifted an 11 day pause on that vaccine, which was recommended by a panel of health officials. The FDA has since lifted the ban, determining that the one dose vaccine is safe to use.
