Oklahoma City, OK – State health department officials note initial doses of last year's vaccine were not received by local health departments and nursing homes until November 7. But from information about distribution this year, officials expect Oklahoma to have half of its total doses in the state by November 1 with another 40 percent arriving in November. They recommend high risk persons--those over age 64, having some chronic health conditions, children from six months to 23 months old, and health care workers--be vaccinated first. Oklahoma's flu season usually arrives late, near the end of December, and the peak is into the new year so vaccination can continue into that time. Comanche County's health department has not yet received vaccine for this flu season.
