The head of Alberta Health Services has apologized for the "frustration and worry" caused by problems during the launch of its online COVID-19 vaccine appointment booking system. Yiu said that AHS made "an error in judgement" when it stress-tested the booking system, and underestimated how many people would use the online tool and call 811 to try and book an appointment at launch time. The technical issues have been fixed, a queuing waiting room is in place, and the system is stable," Yiu said. She said more than 12,000 seniors aged 75 and over have already received their first dose of the vaccine. In her statement, Yiu also addressed reports of line-ups at immunization clinics, as seniors have queued to get theirs shots.
