Deciding About Getting the H1N1 Influenza (Swine Flu) Vaccine
What is the H1N1 flu vaccine?
H1N1 flu, sometimes called swine flu, is a type of influenza that is similar to the common seasonal flu. The H1N1 flu vaccine helps the body build immunity against the H1N1 flu virus. The vaccine causes your immune system to make antibodies. Then if you are exposed to the flu later, the antibodies can attack and destroy the virus.
It takes about 2 weeks for your body to make the antibodies. So the best time to get the vaccine is as soon as it's available in your area.
There are two types of the H1N1 vaccine: a shot(What is a PDF document?) , and a nasal spray(What is a PDF document?) that you breathe in through your nose. The nasal spray vaccine cannot be given to pregnant women and people with some health problems, because it contains a weakened but live form of the virus. But these groups can get the H1N1 shot. Check with your doctor or local health department to find out which type of vaccine is best for you.
Why should you consider getting the H1N1 flu vaccine?
In most cases, H1N1 flu is not serious and you get over it on your own. But in some cases, it might lead to serious illness or even death.
The H1N1 flu vaccine may help keep you from getting the flu. And it can help prevent the spread of the flu to others and help end the worldwide outbreak of the H1N1 flu.
Getting the vaccine is especially important for:
The vaccine may not always keep you from getting the flu, but it can make the symptoms milder and lower the risk of getting other health problems from the flu.
Does the vaccine have risks or side effects you should know about?
Since the H1N1 flu vaccine is new, the risks and side effects are not yet completely known. But the side effects seem to be like the side effects from the seasonal flu vaccine, which can cause mild problems such as soreness, redness, and swelling on the arm where you got the vaccine. Or you may have a fever and muscle aches for a day or two after you get the vaccine. All side effects from the H1N1 flu vaccine won't be known until millions of the vaccines are given.
As people get the H1N1 flu vaccine, the U.S. Centers for Disease Control and Prevention (CDC) and the Food and Drug Administration (FDA) will report any rare or unexpected reactions. For up-to-date information on the vaccine and possible side effects, visit the CDC’s Web site at www.cdc.gov/H1N1flu.
In most cases, the protection the vaccine provides outweighs the risk of getting other health problems from the H1N1 flu.
As with the seasonal flu vaccine, some people should not get the H1N1 flu vaccine without talking to their doctor first. These include people who are allergic to eggs, those who have had a serious reaction to the seasonal flu vaccine in the past, and people who have certain health problems. The H1N1 flu vaccine is not recommended for children younger than 6 months.
Can you get the seasonal flu vaccine and the H1N1 vaccine at the same time?
It depends on the type of vaccines you get. For example, you can get both vaccines at the same time if both are given as a shot or if one is given as a shot and the other as a nasal spray. But you can’t get both vaccines at the same time if both are given through a nasal spray.
Check with your doctor or local health department about what’s right for you. The sooner you get the vaccines, the better. This may mean getting one of the vaccines now and one a little later.
