Due to the heavy flu season, vaccine providers have experienced vaccine shortages in some locations. Call and check with a vaccine provider location to ensure that the vaccine is available.

Here’s what you need to know about the flu shot and other tips for protecting yourself during this particularly bad flu season:

This year's flu vaccine may not be the best match but experts still strongly recommend getting a flu shot. Experts say even if the vaccine is not a perfect match, the vaccine can still help lessen the severity of the flu, and reduce the chance of experiencing severe complications from the flu. Getting a vaccine can also reduce the length of the flu if you do get sick.

It's not too late to get your flu shot. While getting a vaccine earlier in the season is better, there is still a lot of the season to go and vaccination now could still provide some benefit. It takes about two weeks after vaccination for antibodies to develop in the body and provide protection against influenza virus infection.

Flu activity often peaks between December and February and can last through May.

There are other steps you can to take to avoid getting and spreading the flu. Common sense flu prevention techniques really make a difference. Frequently wash your hands with soap and warm water. (If water is not available, alcohol-based gels are the next best thing.) If you are sick, cover your coughs and sneezes with the inside of your elbow or a tissue that is then discarded. Also, don't go to work, and don't have your children go to school, when sick.

What to do if you get the flu. If you do get sick and think you may have the flu, contact your health care provider right away, particularly if you or family members are at high risk for serious flu complications — young children (under the age of 5), those over 65, pregnant women and those with chronic health conditions such as diabetes or asthma. Even young, healthy adults should call their doctor if symptoms don't improve or get worse after three to four days of illness. There are antivirals such as Tamiflu or Relenza that can reduce the duration of flu symptoms but the medication needs to be started within 48 hours of the onset of symptoms to be most effective.
