"We're averaging about 75 calls an hour," said Morris, with St. John's Health Tracks in Springfield. "They're just trying to keep their heads above water up here!"

With two types of flu and a slew of other sickness floating around, the receptionists are on the front lines of health and crowd control. Many parents want their kids vaccinated now, and doctors understand. They just can't always promise patients when vaccines will be available.

"It's extremely frustrating for the parents and it's extremely frustrating for the staff too. It's really all about flexibility and going with the flow," said Morris.

And, even when offices get their doses, they may not always be in the right form.

"The problem we got into is what came in was the nasal spray, the flu mist, so it was a little bit of a Catch-22. All of our high risk kids that we would have had on the waiting list weren't candidates for that vaccine," said pediatrician Dr. Bernard Griesemer.

Still, some doctors say, in time, both vaccines should become more readily available. How long that time is depends on your doctor.

"As soon as the stock is available to us we're going to do our best to get it to everyone we can as quickly as possible," said Morris.
