While you can catch the flu at any time, it's more likely to happen in the colder months of the year. The vaccine takes at least two weeks after inoculation to begin taking effect and as much as six weeks for full protection against the flu. Early signs of the flu can include cough, sore throat, sinusitis or fever and can initially look like the common cold, though the flu is more serious.

If you get sick with the flu, your doctor may prescribe medicines called antiviral drugs. Antiviral medications are available to help reduce the severity of the virus if administered soon after symptoms begin. For those at high risk, antiviral drugs can mean the difference between having a milder sickness or more a serious illness, hospitalization or death. However, antivirals are not a substitute for getting an annual flu vaccination.

Even if you got the flu shot the year before, our immune systems need to acclimate to the flu's adaptations. Influenza develops new strains each year that last years' immunizations may not be able to combat. There are other steps you should take as well to ensure your loved ones and those around you don't get sick.

• Cover your mouth when you cough or sneeze
• Wash your hands as often as you can
• Disinfect surfaces you may have come in contact with
• Avoid interacting with sick people unless for medical purposes

Most individuals get better on their own, but for some people, the flu can be serious - even leading to death. The flu vaccine has proven to be the best way to prevent the flu. Getting your flu vaccine every year is the first and best step to protect yourself and your family from the flu.
