Flu season typically runs from as early as October through May. Many parents have to make the tough decision on whether or not to get themselves and their children vaccinated. With the outbreak of the H1N1 strain, we have even more to worry about. According to the CDC (Centers for Disease Control and Prevention), on average every year in the United States, 5% – 20% of the population gets the flu. The flu can cause hospitalization for up to 200,000 of those individuals and even causes around 36,000 deaths per year. This article will provide some very general information about the flu vaccines available. There are references at the end which I highly encourage visiting to learn more about the options you have for yourself and your family.
Flu vaccinations are often a highly debated topic. Their effectiveness, cost and side effects tend to polarize people regarding the need for the vaccine. Many people feel that the vaccine is unnecessary or even unsafe. There are those who even believe that the flu vaccine is simply a way for drug companies to increase profits at the expense of others. Scientists try to match the virus to the form that is expected to be most prevalent in the upcoming season. While this is not a 100% guarantee that the vaccination will work, it will be effective against many strains.
There are now two types of vaccines available. Both vaccines work on the prinicpal that the body will build up immunity when it comes in contact with the virus. The body is exposed to a dead or weakend version of the virus. The virus causes your body to build up anti-bodies against it therefore helping to prevent a full strength flu virus from growing. This process of building up enough antibodies usually takes around 2 weeks. It should be noted though that the body will only build up the necessary defenses for those strains of the flu that it is injected with.
The first is the traditional “Flu Shot”. The flu shot involves injection of a dead flu virus into the body. Side effects can include but are not limited to:
- a low grade fever for 8 to 24 hours after you receive the shot.
- Soreness or redness around the injection point lasting up to 2 days
- slight chills or a headache within 24 hours
Some people may also suffer more sever allergic reactions to the injection.
The other option involves a nasal spray containing a live but weakened version of the virus. This vaccine is only approved for people 2 to 49 years in age, are healthy and not pregnant. The side effects include many flu like symptoms, but you cannot get the flu from the vaccination. Side effects include but are not limited to:
- runny nose
- nasal congestion
- sore throat
- fever
Many people are concerned that exposing the body to a live virus will cause the flu. According to Melanie Swift, M.D., assistant professor of Medicine and medical director of the Vanderbilt Occupational Health Clinic, and Thomas Talbot, M.D., assistant professor of Medicine and Preventive Medicine, the virus is modified that it cannot reproduce or survive once it is exposed to the temperatures is the human body.
It is important to make any decision regarding vaccination against the flu. Below are some resources and references for this article. It is encouraged to read through them to get all of the fine details not presented here. It is also a good idea to consult medical professionals, especially if you or someone you know is at risk.
