Since the first outbreak back in September of 2008, we are hearing more reported cases of the H1N1 influenza virus throughout the world. By now most of us are familiar with the terms epidemic, pandemic, and know the problem is only increasing. As the flu season is around the corner, we begin to worry on how to prevent from becoming another statistic.

Skipping out on the flu shot is something of the past as this season may be different for everyone. Seasonal flu vaccines are given in two forms either as the flu shot or as a nasal spray, FluMist. The influenza vaccine contains immunization against three types of influenza viruses including influenza A1 (H3N2), influenza type B virus, and influenza H1N1. One important note to consider is that these vaccines do not protect against the 2009 H1N1 virus that is responsible for this current pandemic. Why? This is because the influenza virus which causes the flu every season can change therefore leaving the vaccine ineffective.

FluMist is nasal spray that can be given to children and adults between the ages of 2 - 49. The spray has been ineffective in adults over 50 years of age and is usually not recommended. Health professions recommend 1-2 doses for children depending on previous vaccination history. Adults only need one dose of FluMist. Side effects against FluMist in children generally include runny nose, headache, muscle aches, wheezing. For adults side effects are sore throat, headache, tiredness, and weakness. The idea of inhaling FluMist rather than a painful flu shot is more appealing, however the differences should be considered.

FluMist is made from a live vaccine which means a live influenza virus is introduced into your body. Don’t worry because the flu causing properties from the virus are weak so it cannot cause an infection. When the virus enters your body it allows for your immune system to recognize and build immunity against it. Another difference is obviously that FluMist is a nasal spray which health professionals consider to be ineffective in children with allergies or who have other illnesses. Finally FluMist does not contain the preservative thimerosal. Thimerosal is a mercury containing preservative found in the flu shot. Minor side effects linked to thimerosal includes redness and swelling at the injection site. Since 2008, flu shots have been manufactured without thimerosal however not necessarily carried by every physician so it would be wise to ask your doctor when getting a flu shot.

Whether you decide to get a flu shot or try FluMist, it is probably best to take precautions especially this season where we are confronted with a new 2009 H1N1 influenza virus. Remember the simplest prevention is to wash your hands.
