The Marion County Health Department vaccinated 2,272 people against the H1N1 virus at a free public clinic Saturday at Warren Central High School, according to Health Department spokesman John Althardt.

In total, the Health Department now has vaccinated 11,648 people at four public clinics it has held this fall, Althardt said.

Officials are offering the vaccine to adults considered most at risk of contracting or suffering complications from the virus, including pregnant women, people who live with or care for infants younger than 6 months, anyone from age 6 months to 24 years old, health-care workers and others with pre-existing medical conditions.

The Health Department’s next step is to hold clinics in Marion County’s elementary schools, Althardt added, and that process begins Monday.

Officials hope to complete elementary school vaccinations within two weeks and then move to middle and high schools the week of Nov. 30. They hope to have offered the vaccine to all school-age children before Christmas break, he said.
