Eighty students at the John F. Kennedy schools in Cheektowaga stayed home sick on Tuesday and that number grew to 150 on Wednesday. "That's between middle school and high school so that's out of 1,000 students roughly," says Principal Larry Ljungberg, of JFK high school.

On an average day their number of sick students is approximately 20-to-30. Eric Schaefer, 18, was one of the 150 sick students on Wednesday. He went to school but the nurse sent him home. "I've been throwing up all morning. I've been nauseous for the last couple days and just sick," says Schaefer.

None of the JFK students are confirmed swine flu cases but whether it's swine flu or regular flu schools are trying to limit the spread. "I'm going to the doctor with my family today. We're all going because everyone in my house is sick," says Schaefer.

Parents are encouraged to get their children vaccinated but it's likely not everyone who wants the swine flu vaccine will be able to get it. The first wave of a thousand doses are now in Erie county but approximately 450,000 people in the county are eligible to get the vaccine. "The priority is defined by the Centers for Disease Control and includes a number different populations including pregnant women, health care workers, folks of that type," says Scott Zimmerman, Erie County Director of Public Health Laboratories. The first wave of swine flu vaccine doses will be distributed in the next couple of days and another shipment is expected in Erie county next week.
