Some people should not receive LAIV.
LAIV is not recommended for everyone. The following people should get the inactivated vaccine (flu shot) instead:
Tell your doctor if you have any severe (life-threatening) allergies, including a severe allergy to eggs. A severe allergy to any vaccine component may be a reason not to get the vaccine. Allergic reactions to influenza vaccine are rare.
Tell your doctor if you ever had a severe reaction after a dose of influenza vaccine.
Tell your doctor if you ever had Guillain-Barré syndrome (a severe paralytic illness also called GBS). Your doctor will help you decide whether the vaccine is recommended for you.
Tell your doctor if you have gotten any other vaccines in the past 4 weeks.
Anyone with a nasal condition serious enough to make breathing difficult, such as a very stuffy nose, should get the flu shot instead.
People who are moderately or severely ill should usually wait until they recover before getting flu vaccine. If you are ill, talk to your doctor about whether to reschedule the vaccination. People with a mild illness can usually get the vaccine.
