Influenza vaccination

Routine vaccination

Persons age 6 months or older: 1 dose any influenza vaccine appropriate for age and health status annually
For additional guidance, see www.cdc.gov/flu/professionals/index.htm

Special situations

Egg allergy, hives only: 1 dose any influenza vaccine appropriate for age and health status annually
Egg allergy–any symptom other than hives (e.g., angioedema, respiratory distress): 1 dose any influenza vaccine appropriate for age and health status annually. If using an influenza vaccine other than RIV4 or ccIIV4, administer in medical setting under supervision of health care provider who can recognize and manage severe allergic reactions.
Severe allergic reactions to any vaccine can occur even in the absence of a history of previous allergic reaction. Therefore, all vaccine providers should be familiar with the office emergency plan and certified in cardiopulmonary resuscitation.
A previous severe allergic reaction to any influenza vaccine is a contraindication to future receipt of the vaccine.
LAIV4 should not be used in persons with the following conditions or situations:
- History of severe allergic reaction to any vaccine component (excluding egg) or to a previous dose of any influenza vaccine
- Immunocompromised due to any cause (including medications and HIV infection)
- Anatomic or functional asplenia
- Close contacts or caregivers of severely immunosuppressed persons who require a protected environment
- Pregnancy
- Cranial CSF/oropharyngeal communications
- Cochlear implant
