Those who have been vaccinated can still get the flu, but some people confuse colds with the flu too. FOX 9 News spoke with Dr. Archelle Georgiou about the difference.

It takes about two weeks for the vaccine to take effect. If someone gets exposed to the flu before their immune system has reacted, they could still get sick. It's also possible that someone could get exposed to a strain of the flu virus that's not covered by the vaccine.

Although this year's vaccine looks to be a good match for the most common flu strains that are circulating this year, a three-year study at the University of Minnesota contradicts the conventional wisdom that the flu vaccine is 70 to 90 percent effective. Rather, a flu shot is no guarantee of protection.
