AdTo the public health agency’s credit, in short order in the dead of night in a storm, not a single shot was wasted, according to the county. More than 5,400 of those vaccines were rushed to three hospitals, Rice University and the Harris County Jail. “I could never imagine we were going to go through this.”AdThis week, Harris County sent out messages informing patients their second doses would be rescheduled and that process is starting now. “Just be patient because everybody is going through a hard time.”AdWe asked Harris County Public Health about the cold storage failure and if they planned on making any changes moving forward.
