Maine’s health director says the need for swine flu vaccine is widening as the disease spreads throughout the state. Dr. Dora Ann Mills of the state Center for Disease Control and Prevention said Thursday that the shortage is very frustrating for those who want the vaccine. Mills says there’s only enough vaccine for less than two-thirds of high-priority people who need it, including pregnant women and children. In her weekly update, Mills said the state’s expected to have a total of 210,400 doses of vaccine by tomorrow. She said 50 people have been hospitalized in the last week, half of them children. Mills says it’s not clear when the disease will peak in Maine, but she hopers it’ll be in the next couple of weeks.
