The Carl R. Darnall Army Medical Center resumed COVID-19 vaccinations Wednesday for people whose second dose was due in February, but one veteran said he was recently turned away from receiving his scheduled second dose. âI took the first shot on the 8th of February,â James Anderson, of Killeen, told the Herald Wednesday. âI was supposed to take the second one on the 1st of March. I went on the 1st of March and there was no vaccine.â Now, Anderson said, he wonders if too much time will pass between his first and second shots, if he doesnât get it soon.
