Now they've gotten in a small shipment of swine flu shots that matches one district's numbers, so they are set for Wednesday.

Of the approximately 750 students at Bridgeport, 230 returned the form saying yes to the shot.

So Wednesday evening, they will come to the school from five to eight p.m. to get their shots.

If your child has not returned a consent form by now, he or she will not get the shot this time.

"We'll be conducting mass clinics later on," said Rob Sproul of the Belmont County Health Department. "That's why we sent out consent forms weeks ago, to get good numbers. Because the state is only sending us vaccines in limited amounts."

As for the children who did sign up, if they should be feeling sick on Wednesday, health department officials have one message for them: Stay home.

They promise they will not give that child's shot away.

It will be saved and administered once the child is feeling better.

"By sending in that consent form and basically reserving that shot, we're gonna honor that and get that shot to them," Sproul said. "But we don't want them to come into school ill and get other kids sick."

This batch of vaccine does have Thimerosol, a mercury-based preservative.

"The FDA has done extensive testing on it and they say it is very safe," said Sproul. "There have been concerns in the past that it has contributed to autism, but they have not found any real data to show that that's the case."

At first, health department officials were under the impression that preservative-free vaccine would be available for anyone who chose it.

They have now learned it will only be available for infants.

All the students coming Wednesday night need to bring a parent with them in order to get the shot.
