Ron DeSantis expanded vaccine eligibility to those 65 years and older using an executive order, hundreds of people in Lee County, which includes Fort Myers, brought coats, chairs, blankets and tents to wait in line overnight Tuesday and get the vaccine on Wednesday.“Supply is limited,” DeSantis said Wednesday. “We don’t have enough vaccines for all 4 million plus senior citizens in Florida.”Abdulla Benkhatar, who is 90 and was first in line at a local recreation center, told ABC News Fort Myers affiliate WZVN-TV that he began waiting at 10 a.m. Tuesday.“We’ve been at home for almost 10 months now,” Benkhatar said. “It’s really important to me, for my health, and to be able to do things I like to do and get back to normal.”In Puerto Rico, health care workers have consistently been lining up at the Pedrin Zorrilla Coliseum in San Juan trying to get vaccinated, according to the Miami Herald.Some had returned multiple nights in a row to try and get a shot, while others had defied Puerto Rico’s 9 p.m. curfew to line up on a highway overnight.Copyright © 2021, ABC Audio.
