If you aren't invited to the vaccine clinic in Sioux Falls, kids can get the H1N1 and seasonal flu vaccine Thursday in Vermillion. At this point, Vermillion is one of four communities chosen by the state Department of Health to provide vaccines to a large group of people facing an infectious disease outbreak like H1N1.  Thursday, the community will be put to the test as health officials there welcome children from all over the region to get vaccinated. 

An empty Vermillion High School gymnasium will be transformed Thursday into a mass vaccination clinic but not everyone should line up.

"On the seasonal flu, it's ages six months through 18 years and on the H1N1, it's six months only through age four," Vermillion Mayor Dan Christopherson said. 

This site has also added pregnant women to the list. They're guidelines Vermillion Mayor Dan Christopherson says will stand firm.

"There will be a screening process to make sure the individuals do meet the criteria because this is mandated by the state Department of Health and we do have to follow their guidelines," Christopherson said.

Tents will be set up outside to make sure those children eligible get in line and those who are not head back home. Christopherson says there will be more clinics, but young children who are at highest risk will receive the first available doses.

"The best thing we can do with this vaccine, since we now have it in the community, is get it in the people. We need to be giving them protection as soon as possible so our goal is to use it all up and we hope that we will," Christopherson said.

With large crowds expected to show up, Christopherson says there's a plan in place if things get out of hand. 

"We definitely have security and people need to obey the law. They need to follow the instructions of the personnel in charge of the clinic," Christopherson said.

The clinic Thursday at Vermillion High School begins at 2 p.m. and ends at 7p.m.  Christopherson says he fully expects there will be another clinic soon because small children getting the H1N1 vaccine will need a second dose in about a month.
