Influenza Vaccine, Live Intranasal
Why get vaccinated?
Influenza ("flu") is a contagious disease that spreads around the United States every winter, usually between October and May.
Flu is caused by the influenza virus, and can be spread by coughing, sneezing, and close contact.
Anyone can get flu, but the risk of getting flu is highest among children. Symptoms come on suddenly and may last several days. They can include:
Flu can make some people much sicker than others. These people include young children, people 65 and older, pregnant women, and people with certain health conditions-such as heart, lung or kidney disease, or a weakened immune system. Flu vaccine is especially important for these people, and anyone in close contact with them.
Flu can also lead to pneumonia, and make existing medical conditions worse. It can cause diarrhea and seizures in children.
Each yearthousands of people in the United States die from flu, and many more are hospitalized. Flu vaccine is the best protection we have from flu and its complications.
Flu vaccinealso helps prevent spreading flu from person to person.
What is live, attenuated influenza vaccine-LAIV (nasal spray)?
There are two types of influenza vaccine:
You are getting alive, attenuated influenza vaccine(called LAIV), which is sprayed into the nose. "Attenuated" means weakened. The viruses in the vaccine have been weakened so they can't make you sick.
A different vaccine, the "flu shot," is aninactivatedvaccine (not containing live virus). It is given by injection with a needle.This vaccine is described in a separate monograph, Influenza Vaccine, Inactivated.
Flu vaccine is recommended every year. Children 6 months through 8 years of age should get two doses the first year they get vaccinated.
Flu viruses are always changing. Each year's flu vaccine is made to protect from viruses that are most likely to cause disease that year. While flu vaccine cannot prevent all cases of flu, it is our best defense against the disease. LAIV protects against 4 different influenza viruses.
It takes about 2 weeks for protection to develop after the vaccination, and protection lasts several months to a year.
Some illnesses that arenotcaused by influenza virus are often mistaken for flu. Flu vaccine will not prevent these illnesses. It can only prevent influenza.
LAIV may be given to people2 through 49 years of age, who are not pregnant. It may safely be given at the same time as other vaccines.
LAIV does not contain thimerosal or other preservatives.
Who should not get or should wait to get LAIV?
Tell the person who gives you the vaccine:
You should get the flu shot instead of the nasal spray if you:
The person giving you the vaccine can give you more information.
What are the risks from LAIV?
With a vaccine, like any medicine, there is a chance of side effects. These are usually mild and go away on their own.
Serious side effects are also possible, but are very rare. LAIV is made from weakened virus anddoes not cause flu.
Mild problemsthat have been reported following LAIV:
Children and adolescents 2-17 years of age:
Adults 18-49 years of age:
Severe problemsthat could follow LAIV:
