"We know that influenza has been around for a long time, and the risk for not being immunized is very high," said Doshi. "The secondary complications are getting worse in ways of prevention, so we need to look at preventing the flu."
Although flu shots do not guarantee protection from MRSA pneumonia or other respiratory infections, Finelli said protection from symptoms that attract MRSA is all the more reason to get a flu shot this season.
"You can't prevent the bacteria, but if you prevent the flu, you prevent the co-infection," said Finelli. "These infections together are more fatal than one alone."
With hopes of encouraging the public to vaccinate, the CDC recently released a video testimonial of families who have lost children from complications related to the flu. In an emotional confession, each family claims their child's death could have been prevented by the flu vaccine.
Dr. William Schaffner, professor of medicine in the division of infectious diseases at Vanderbilt University, said getting the flu shot -- which is available from late September through early spring -- does not mean that you will not get the flu, but it may prevent the transmission of life-threatening symptoms caused by the flu. Each year, a new vaccine is created to accommodate the changing strain of the virus.
"Even if [the flu] doesn't match the vaccine strain of the year, you do get some protection," Schaffner said. "Partial protection is better than none."
Indeed, many physicians recommend the flu shot to all their patients -- regardless of age. But a number of patients still refuse. A few years ago, Diane McGowan, featured in the CDC's video, was one mother who did not see the need for her and her family to get annual vaccinations.
"I was a parent that had the misconception that we didn't need the flu shot unless we had a chronic illness," said McGowan. That was her feeling until 2005, when her 15-year-old son, Martin, died from influenza.
Schaffner said misinformation about the vaccine keeps some people from getting the flu shot. One myth, he said, is that a person can get the flu from getting the flu vaccine.
"Because we administer the shot during the cold season, you may get the shot when you have already developed cold symptoms," Schaffner said.
The CDC also recommends avoiding close contact with others, even if they do not have influenza, as well as taking antiviral medications. McGowan said, along with an annual flu shot -- which she and her family now receives -- community awareness is also an important method of prevention.
McGowan has created the nonprofit organization M.A.R.T.I.N. (May All Receive Their Immunizations Now) Flu Foundation, which she hopes will educate others about the severity of the flu and the importance of vaccinations.
"Every time I see the number of deaths from the flu, it kills me," McGowan said. "Because I know it's preventable."
