An influenza vaccine can reduce the chance that you get ill with the flu and pass it on to others.
Vaccine - influenza; Immunization - influenza; Flu shot; Flu vaccine
The flu is a respiratory disease that spreads easily. It is caused by an influenza virus. Thousands of people in the U.S. die each year of the flu or its complications. Most of those who die are the elderly, young children, or people with a weakened immune system.
Each year the flu vaccine is made to protect against the strains of the flu virus that scientists expect to be most common. Talk with your health care provider about which of the following vaccines you should receive:
The flu vaccine comes in two forms: a flu shot and a nasal spray.Your health care provider can recommend which of the two forms you should receive.
THE FLU SHOT
THE FLU NASAL SPRAY
Vaccines made without eggs are available for people who are allergic to eggs. These vaccines are called recombinant vaccines. Ask your health care provider if these are safe for you.
WHO SHOULD GET THE FLU VACCINE
The flu vaccine should be received at the start of the flu season. This is around October in the U.S. The vaccine can be received as late as March and still provide some protection. People traveling to other countries should be aware that the flu may be more common at different times of the year from the U.S.
The Centers for Disease Control and Prevention (CDC) recommends that everyone, 6 months and older, should receive the flu vaccine. Some people are more likely to get the flu or to have a severe infection if they catch it. People at risk of more serious flu infections should always get a flu vaccine every year. The CDC recommends making an extra effort to vaccinate:
Persons 9 years and older need a single flu shot each year. Children 6 months to 8 years old should get two shots at least 1 month apart if they are getting the flu vaccine for the first time. Be sure to ask your child's doctor for more specific information.
Most people are protected from the flu about 2 weeks after receiving the vaccine.
RISKS AND SIDE EFFECTS
Most people have no side effects from the flu vaccine. Soreness at the injection site, minor aches, or a low grade fever may be present for several days.
As is the case with any drug or vaccine, there is a rare possibility of allergic reaction.
The regular seasonal flu shot has been shown to be safe for pregnant women and their babies.
Normal side effects of the nasal spray flu vaccine include fever, headache, runny nose, vomiting, and some wheezing. Although these symptoms sound like symptoms of the flu, the side effects do not become a severe or life-threatening flu infection.
WHO SHOULD NOT GET THE VACCINE
The flu vaccine is not approved for people under 6 months of age. Some people should not be vaccinated without first talking to their doctor. In general, you should not get a flu shot if you:
If any of the above applies to you, ask your doctor if a flu vaccine is safe for you.
If you are allergic to chickens or egg protein, ask your doctor if you can safely receive the recombinant vaccine, which is not made from chicken eggs.
