What is the nasal spray flu vaccine?
There are two types of flu vaccine: the
flu shot and the nasal spray vaccine. Both types of vaccine are being made
against 2009 H1N1. The nasal spray flu vaccine (sometimes called LAIV for Live
Attenuated Influenza Vaccine) is a vaccine made with live, weakened viruses that
cannot grow at normal body temperature and is given via a nasal sprayer.
This
vaccine was approved for seasonal influenza viruses in 2003 and tens of millions
of doses of the vaccine have been given in the United States.
How is the 2009 H1N1 nasal spray vaccine different from the seasonal nasal
spray vaccine?
The 2009 H1N1 nasal spray vaccine is being made in the same way as the
seasonal nasal spray vaccine, but instead of containing three weakened live flu
viruses, it only contains weakened 2009 H1N1 virus. (That is why it' is called a
"monovalent" vaccine.). The recommendations for who can get the 2009 H1N1 nasal
spray vaccine are the same as for seasonal nasal spray vaccine. LAIV is
recommended for use in healthy* people 2 years to 49 years of age who are not
pregnant.
Who can be vaccinated with the 2009 H1N1 nasal-spray flu vaccine (LAIV)?
The 2009 H1N1 nasal spray vaccine is recommended for use in healthy people 2
years Through 49 years of age who are not pregnant. See below
Can health care providers get the live attenuated influenza vaccine?
Yes. LAIV is a very good option for most health care providers who are
healthy, younger than 50 years old, and not pregnant. However, health care
providers should not get LAIV if they are providing medical care for patients
who require special environments in the hospital because they are profoundly
immunocompromised (e.g., those who work in bone marrow transplant units).
Although no immunocompromised patient has been shown to be harmed by use of LAIV
among health care workers, the recommendation against the use of LAIV in health
care workers with this type of patient contact is intended as an extra
precaution for fragile immunocompromised patients. Health care workers with this
type of patient contact can get LAIV, but if they do, they should wait 7 days
after being vaccinated before returning to duties that include care of severely
immunocompromised patients in special environments.
Who should not be vaccinated with the 2009 H1N1 nasal-spray flu vaccine LAIV?
Certain people should not get a nasal spray flu vaccine, including the 2009
H1N1 nasal spray vaccine. This includes:
- People younger than 2 years of age;
- Pregnant women;
- People 50 years of age and older;
- People with a medical condition that places them at higher risk for
complications from influenza, including those with chronic heart or lung
disease, such as asthma or reactive airways disease; people with medical
conditions such as diabetes or
kidney failure; or people with illnesses that
weaken the immune system, or who take medications that can weaken the immune
system;
- Children younger than 5 years old with a history of recurrent wheezing;
- Children or adolescents receiving
aspirin therapy;
- People who have had Guillain-Barré syndrome (GBS), a rare disorder of the
nervous system, within 6 weeks of getting a flu vaccine,
- People who have a severe allergy to chicken eggs or who are
allergic to any of the nasal
spray vaccine components.
Should the nasal-spray flu vaccine be given to patients with chronic diseases other than those specifically listed above?
No. The nasal-spray flu vaccine is approved for use only in healthy* people 2
years to 49 years of age who are not pregnant.
