Orange County Supervisors Slam Othena App for Vaccines Supervisor Don Wagner said many of his constituents have called him to complain about Othena. “Othena sucks,” Wagner said. “I’m getting that from 65-plus-year-old constituents of mine who are using that word. It’s a mess. It’s gotten better, but you know it’s a mess. Everyone on this board knows it’s a mess.” Dr. Clayton Chau, the county’s chief health officer and director of the Orange County Health Care Agency, defended the app and website, which he authorized before informing the board. “When setting up a system, there’s always glitches,” Chau said, adding that in recent days it has “improved significantly.”
