First there were professional athletes. Then hospital boards. Now students at some private schools have received preferential access to flu shots.

Officials from St. Andrew’s College in Aurora, Pickering College in Newmarket and the Hill Academy in Concord acknowledged yesterday that some students and staff have received the vaccine even though they are not among the high-risk groups designated by the province for early shots.

Private schools and boarding schools are not among the province’s priority groups, and Ontario’s top public health official Dr. Arlene King told a news conference yesterday that people must follow the sequencing order because supply of the vaccine is still limited and those at high risk need it first.
