The Nassau County Department of Health set up an inoculation center Friday hoping to vaccinate 800 pregnant residents against swine flu.

Health Commissioner Dr. Maria Toroella-Carney says a new study found pregnant women are four times more likely to be hospitalized for swine flu and six times more likely to die from it, when compared to the general population.

Despite the urging of health officials, some pregnant women remain skeptical and say they won?t get vaccinated against H1N1. Toroella-Carney says there?s no evidence or study supporting the idea that the vaccine is dangerous.
