Even healthy people need a flu vaccine.

Even healthy people need a flu vaccine.

Influenza (flu) is a contagious disease which affects the lungs and can lead to serious illness, including pneumonia. Even healthy people can get sick enough to miss work or school for a significant amount of time or even be hospitalized. The flu vaccine is recommended for everyone 6 months of age and older. Pregnant women, young children, older people, and people with certain chronic medical conditions like asthma, diabetes and heart disease are at increased risk of serious flu-related complications, so getting a yearly flu vaccine is especially important for them.

Is the flu vaccine safe?

Is the flu vaccine safe?

Yes. Flu vaccines are safe. They have been given to hundreds of millions of people for more than 50 years and have a very good safety track record. Each year, the Centers for Disease Control and Prevention (CDC) works closely with the U.S. Food and Drug Administration (FDA), and other partners to ensure the highest safety standards for flu vaccines.

The most common side effects of flu vaccines are mild.

The most common side effects of flu vaccines are mild.

The flu vaccine cannot cause flu illness; however, it can cause mild side effects that may be mistaken for flu. For example, people vaccinated with the flu shot may feel achy and may have a sore arm where the shot was given. People vaccinated with the nasal spray flu vaccine may have a stuffy nose and sore throat. These side effects are NOT the flu. If you do experience them at all, these effects are usually mild and last only 1-2 days. And that’s much better than getting sick and missing several days of school or work or possibly getting a very severe illness and needing to go to the hospital.

Even if I get sick, won’t I recover quickly?

Even if I get sick, won’t I recover quickly?

Not necessarily. Influenza can be serious, and anyone can become sick with the flu and experience serious complications. But even if you bounce back quickly, others around you might not be so lucky. Older people, young children, pregnant women and people with medical conditions like asthma, diabetes, heart disease and lung disease are at especially high risk from the flu. Kids, teens and adults who are active and healthy also can get very sick from flu and spread it to others. Some people can be infected with the flu virus but have no symptoms. During this time, you can still spread the virus to others. Don’t be the one spreading flu to those you care about.

Can’t I wait and get vaccinated when the flu hits my community?

Can’t I wait and get vaccinated when the flu hits my community?

It is best to get vaccinated before flu begins to spread. If you wait until people around you get sick from flu, it will probably be too late to protect yourself. It takes about two weeks for the flu vaccine to provide full protection, so the sooner you get vaccinated, the more likely it is that you will be fully protected once flu begins to circulate in your community.

Flu vaccines can’t give you the flu.

Flu vaccines can’t give you the flu.

Even if you got a flu vaccine, there are reasons why you might still get flu or a flu-like illness:

  • You may have been exposed to a non-flu virus before or after you got vaccinated. The flu vaccine can only prevent illnesses caused by flu viruses. It cannot protect against non-flu viruses that cause flu-like illness.
  • Or you might have been exposed to flu after you got vaccinated but before the vaccine took effect. It takes about two weeks after you receive the vaccine for your body to build protection against the flu.
  • Or you may have been exposed to an influenza virus that was very different from the viruses included in that year’s vaccine. The flu vaccine protects against the influenza viruses that research indicates will cause the most disease during the upcoming season, but there can be other flu viruses circulating.
  • Unfortunately, the flu vaccine doesn't provide the same protection for everyone. How well the flu vaccine works can range widely from season to season and also can vary depending on who is being vaccinated.

Don't avoid getting a flu vaccine because you dislike shots.

Don't avoid getting a flu vaccine because you dislike shots.

The very minor pain of a flu shot is nothing compared to the suffering that can be caused by the flu. The flu can make you very sick for several days; send you to the hospital, or worse. For most healthy, non-pregnant people ages 2 through 49 years old, the nasal spray flu vaccine is a great choice for people who don’t like shots. Also, there is an intradermal shot that uses a much smaller needle than the regular flu shot. Either way, a shot or spray can prevent you from catching the flu. So, whatever little discomfort you feel from the minor side effects of the flu vaccine is worthwhile to avoid the flu.

You need to get a flu vaccine every year.

You need to get a flu vaccine every year.

There are two reasons for getting a flu vaccine every year:

  • The first reason is that because flu viruses are constantly changing, flu vaccines may be updated from one season to the next to protect against the viruses that research suggests are most likely to circulate each season.
  • The second reason annual vaccination is recommended is that your body’s level of immunity from a flu vaccine received last season is expected to have declined. You need to get vaccinated every year for the best protection against the flu.
