Influenza

UPDATED 9/19/2016

WE CURRENTLY HAVE INJECTABLE FLU VACCINE

 PLEASE CONTINUE TO CHECK OUR WEBSITE FOR UPDATES

 

The CDC and the Academy of Pediatrics recommend that ALL children and adolescents older than 6 months be immunized, especially those with chronic illnesses such as asthma.

This year's vaccine will be available in two forms:

  1. Quadrivalent inactivated injectable
  2. Quadrivalent live attenuated vaccine for nasal inhalation

The number of seasonal influenza vaccine doses to be administered this year depends on the child's age and vaccine history:

  • Influenza vaccine should not be given to infants less than 6 months of age.
  • Children 9 years of age and older need only one dose of vaccine regardless of whether they have received earlier doses of influenza vaccine.
  • Children younger than 9 years who receive seasonal influenza vaccine (injection or intranasal) for the first time should receive a second dose this season at least 4 weeks after the first.
  • Children 6 months through 8 years of age who received trivalent seasonal influenza vaccine PRIOR TO the 2014-2015 influenza season:
    • Need only 1 dose of vaccine, if they previously received a total of 2 or more  doses of seasonal vaccine
    • Need 2 doses of vaccine, if they did not previously receive a total of 2 or more doses of seasonal vaccine

The CDC and the Academy of Pediatrics strongly recommend beginning community-wide immunization efforts AS SOON AS vaccine is available; protective immune responses persist throughout the influenza season. Immunization should continue until vaccine supplies are exhausted each season to ensure that as many children as possible receive the optimal number of doses.

There will be one type of flu vaccine available for 2015-2016. This will provide protection against 4 strains (quadrivalent) of the Influenza virus. The vaccine is prepared using eggs and those with severe egg protein allergy should receive vaccine. The vaccine is not 100% effective in preventing influenza, and needs to be given yearly for ongoing protection. In general, those who receive the vaccine and become ill with the flu can expect to experience less severe illness and a significantly decreased risk of hospitalization and/or death.

The first type is the typical “flu shot” (inactivated influenza vaccine) available to kids older than 6 months. This year there will be 1 type of this vaccine:  Quadrivalent inactivated vaccine for children > 6 months of age. There is no upper age limit for those receiving Inactivated influenza vaccine which contains killed viruses, and thus cannot cause true Influenza. these vaccines may cause mild fever and soreness at the injection site in 10-35% of recipients during the first 24 hours after injection, especially in children under 2 years of age.The inactivated vaccines can be administered to those with chronic medical conditions, those with immunodeficiency, and those who might be closely exposed to immunocompromised individuals.

The second type of flu vaccine is FluMist (live attenuated influenza vaccine- LAIV) administered as a nasal spray. It is indicated in the prevention of disease caused by influenza A and B viruses in healthy children and adolescents, 2 to 17 years of age, and healthy adults, 18 to 49 years of age. Because it is a live attenuated viral vaccine there is a small potential for it to cause mild flu-like symptoms a few days after administration. It is a quadrivalent vaccine.

FluMist is contraindicated in the following circumstances:

  1. Children with severe hypersensitivity to eggs
  2. Children receiving aspirin therapy
  3. Children with a history of Guillain-Barre syndrome
  4. Children with known or suspected immunodeficiency or who are currently immunosuppressed.
  5. Children who will have a household contact with immunodeficiency or immunosuppression.
  6. Children with significant nasal congestion; the vaccine should be delayed until the nasal congestion has abated.
  7. Pregnant women
  8. Children with diabetes
  9. Children with kidney dysfunction
  10. Children with sickle cell disease
  11. Children with moderate to severe asthma (reactive airway disease)
  12. Children with a significant febrile illness within the past 3 days
  13. Children who have taken an antiviral medication within the last 2 days or who are anticipated to to need an antiviral medication within 2 weeks of administration of FluMist.

Both types of vaccine (inactivated & live attenuated) are considered to be equally effective.
