The need is off the charts for vaccinating the most vulnerable for swine flu.
"There's been a robust response, we have a very filled waiting room in our immunization area," said Dr. Dean Sienko of the Ingham County Health Department.
"The orders are coming in very fast," said Bob Swanson of the Michigan Department of Community Health.
Swanson says every county health department in the state has received doses of the vaccine, and the orders keep coming in.
"We're trying to fill the orders as quickly as possible and get as much vaccine out to the community as we can," Swanson said.
But Swanson says the first batch of doses delivered to health department fell short of expectations.
"Unfortunately the allocation that we're receiving from the CDC are smaller than we anticipated, the vaccine is going through a process and it's coming out slower than we anticipated, so overtime we expect over the upcoming weeks and months, we expect a lot more vaccine to be available," Swanson said.
The Ingham County Health Department hasn't run out the vaccine yet but they're counting on more.
"So, we can continue to broaden the people we cover with the vaccine," Sienko said.
The Health Department is authorized to receive 2800 doses of the flu mist and 4600 doses of the injectable vaccine next week.
"And we believe the system is gong to work, so we send our orders up and we expect to get vaccine on time," Sienko said.
And state health officials say as long as the orders keep coming in, the CDC will keep delivering.
"CDC has committed to making enough vaccine available so we can continue to order it as long as there's a demand," Swanson said.
