There just isn't enough for everyone.
That's why hundreds of people lined the streets of South Sioux City hoping to get their hands on an H1N1 vaccine.
People were anxiously waiting as if they were in line for a rollercoaster.
But instead, they were hoping for the chance to get vaccinated for the H1N1 virus.
"I am very nervous about the H1N1. The cut off is 49, I just turned 50 and I would love to have it but the kids do have to come first I realize that."
Hundreds of people literally lined the streets of Dakota Avenue where the clinic was held.
The first priority group was able to receive the flu nasal mist, but not everyone in line today was able to get it.
While there are only 400 vaccinations available, county officials say it's a good start.
"H1N1 is becoming quite a problem, we need to make the preventatives aware to the public, that's what we're doing today, we have priority groups, we're addressing them in that order, and we just think we need to make that available to those people that want it."
This was the first public clinic for Dakota County.
Medical officials say they will hold as many of these clinics as possible, as long as vaccines keep coming in.
Public clinics for H1N1 are free to anyone, because the government is footing the bill.
