Free in-school H1N1 vaccination clinics begin tomorrow for students in kindergarten through eighth grade, and over the next few months more than 300 clinics will be held at public and private schools across Hawai'i.

These clinics are separate from the in-school vaccination clinics under way for the seasonal flu.

Even though the Centers for Disease Control and Prevention recommends two doses of H1N1 vaccine, four weeks apart, for children ages 9 and younger, only the first dose will be provided at school-based clinics.

Parents should get the second dose from their child's medical provider, according to the state Department of Health.

School-age children are among the high-risk groups for the H1N1, or swine flu, virus.

The first vaccinations were offered to health care workers, and emergency medical service and critical civil defense personnel.

According to CDC guidelines, next in line for the vaccinations is anyone between the ages of 6 months and 24 years; pregnant women; caretakers of infants less than 6 months; and people through age 64 who have chronic medical conditions that make them susceptible to complications from flu.
