Flu season is here and after months of planning and testing, the first batches of H1N1 swine flu vaccine become available this week.
More than seven million doses of the vaccine will be available to the public Monday.
"This is clearly the most ambitious influenza vaccination program ever mounted in the United States or anywhere in the world. The number of doses of vaccine. The quickness with which the vaccine has been produced," said Vanderbilt School of Medicine's Dr. William Schaffner.
This week doctors will receive 600,000 tubes of nasal spray vaccine and six million doses of the vaccine ready for innoculations. Another 40 to 50 million vaccine doses should be ready next week.
However, some people say they won't be getting the vaccine.
"I don't think I'll get the swine flu vaccine," Laura Thomas said. "I'm not terribly concerned about getting the swine flu."
Health officials advise pregnant women to receive the vaccine, since they are particularly vulnerable to the disease. So far, 28 pregnant women have died due to swine flu.
Health care workers are also being urged to get the vaccine.
Health officials say young people ages six months to 24-years-old and people with chronic health conditions - such as asthma, obesity and diabetes - who are at greater risk of complications from the flu should be priority in getting the vaccine.
