Test trials of an H1N1 vaccine have begun, and today the Centers for Disease Control have decided who should be at the top of the list to get vaccinated.
Clinical trials are underway right now but the vaccine won't be ready for distribution until Mid October.
Then once it is ready there won't be enough for everyone so health officials have had to create a priority list.
First up everyone six months to 24 years old; that's to help prevent the spread of the virus and protect the weak.
Health care workers, adults 24 to 64 with medical conditions, and pregnant women are also high on the list.
Another thing that's new is studies show expectant mothers have a significantly higher risk of death from the Swine Flu putting them near the top of the priority list.
"There will not be enough for everyone. We will have to prioritize," said Dr. William Schaffner of Vanderbilt Medical School.
Kim Kaiser is 22– weeks pregnant, which means she'll be entering her third trimester just as the seasonal flu season hits.
Kim is paying close attention to what her doctor says.
"I will be very careful to follow my doctor's orders as far as getting vaccinations for seasonal flu or an H1H1 vaccination if it becomes available," said Kim.
Dr. Timothy Burke is somewhat hesitant about the H1N1 vaccination, he says he's waiting for recommendations from the C.D.C. and state health departments.
But, he says, if it's like the seasonal flu vaccine, pregnant women need not worry about repercussions from the vaccine.
"Pregnant women have been one of the high priority groups for years and the potential benefit of a flu vaccine outweighs the risks," said Burke.
If efforts to create an H1 N1 vaccination don't work, the CDC says 40– percent of the population could come down with swine flu in the next two years, and deaths could climb into the hundreds of thousands- that's why these upcoming clinical trials are so important.
Doctors recommend everyone get the regular seasonal flu vaccine- it won't protect you from H1N1, but will help in what could be a dangerous flu season.
