Nancy Baran has been following the recommendations on how to avoid swine flu very closely.
"I heard, get the regular seasonal flu shot and then the swine flu shot also," she explains.
And that was the plan, at least until she heard about four studies out of Canada that looked at a total of four thousand patients. Basically, the study shows that you may be more likely to get swine flu if you get vaccinated against the seasonal flu first.
That's making Baran rethink that free flu shot she was going to get from work.
"I'm around young kids, I work, I can't afford to miss work, I can't afford to not be around other people," Baran explains.
And now she feels like she's in a lose/lose situation. Get the vaccine--get sick, don't get the vaccine-- get sick.
"I'm totally confused, I don't know what to do. Should I get it or should I not get it?" she asks.
But the worry isn't necessary-- says Dr. Dean Sienko of the Ingham County Health Department.
"I think these studies are premature, they don't meet the standards of good science," Sienko says.
He adds, if you do truly want to avoid swine flu, one flu and one swine flu shot will pave the way.
"I am not planning on altering my behavior or my family's behavior in terms of getting all of these influenza shots because of a study like this," he explains.
