In a mid-course change, Ontario is delaying its seasonal flu vaccine program for most people until after the swine flu vaccine is administered.
Dr. Arlene King, the province's chief medical officer, says people 65 and older, who are at greater risk from seasonal flu, will get their traditional flu shots starting in October.
When the swine flu vaccine becomes available in November, all the people who want to be vaccinated will be given access to those shots.
Once that's finished the seasonal flu shot program will resume.
King says they're making the adjustments because studies suggest the swine flu may hit children and adults under 60, while seasonal flu primarily seems to target people over 65.
