Image: Intradermal vaccine needles are injected into the skin rather than deep into the muscle.

Typical vaccine needles go through the skin, then a layer of fat, and finally enter the muscle.1 Intradermal vaccines are injected into the skin through a small, ultra-thin needle.2,3 Because the skin has more immune cells than the muscle, an intradermal vaccine is able to use the skin's natural defenses, providing a similar level of protection as the traditional flu shot.2,4

The Fluzone Intradermal vaccine needle is comparable in size to a penny.

How is Fluzone Intradermal vaccine different from the flu shot I received last year?

The microneedle only goes as deep as the skin.2,3 It contains less vaccine than the traditional flu shot (0.1 mL compared to 0.5 mL) and is designed to help protect you against the flu.2,5

Where is the microneedle injected?

Fluzone Intradermal vaccine is given in your upper arm — the same spot you were given your flu shot from last year.2,5

How small is the microneedle?

Fluzone Intradermal vaccine is the first FDAa-approved intradermal flu vaccine in the United States.6 The ultra-thin tip is only 1.5 mm long; that's the same thickness of a US penny!3,7

a FDA = Food and Drug Administration.

What reaction, if any, can I expect from Fluzone Intradermal vaccine?

The most common side effects are redness, swelling, or a raised bump where the vaccine was injected.2 This is because the vaccination is given just under the skin.8 Other side effects include pain and itching.2 These reactions typically are not serious and generally resolve on their own within a few days.6

Is Fluzone Intradermal vaccine for everyone?

Fluzone Intradermal vaccine is approved only for adults 18-64 years of age.2 However, other flu vaccines are available for patients 6 months of age and older.5

How much does Fluzone Intradermal vaccine cost?

Flu vaccines are typically covered by most insurance companies.9 In addition, coverage for children, adolescents, and others are mandated under the provisions of the Affordable Care Act.10 For more information on your specific influenza vaccine coverage, please contact your insurance company.

Important Safety Information

Indication

Fluzone, Fluzone Intradermal, and Fluzone High-Dose vaccines are inactivated influenza virus vaccines given for active immunization against influenza disease caused by influenza A and B strains contained in the vaccine.

Fluzone vaccine is intended for persons 6 months of age and older.

Fluzone Intradermal vaccine is intended for persons 18 through 64 years of age.

Fluzone High-Dose vaccine is intended for persons 65 years of age and older. Approval of Fluzone High-Dose vaccine is based on superior immune response relative to Fluzone vaccine. Data demonstrating a decrease in influenza disease after vaccination with Fluzone High-Dose vaccine relative to Fluzone vaccine are not available.

Safety Information

Side effects to Fluzone and Fluzone High-Dose vaccines include pain, redness, and swelling at the injection site; muscle aches, fatigue, headache, and fever (irritability, crying, and drowsiness in young children receiving Fluzone vaccine). Redness, firmness, swelling, and itching at the injection site occur more frequently with Fluzone Intradermal vaccine than with Fluzone vaccine. Other side effects may occur. Fluzone, Fluzone Intradermal, and Fluzone High-Dose vaccines should not be administered to anyone with a severe allergic reaction to any vaccine component, including eggs, egg products, or thimerosal (the only Fluzone vaccine product containing thimerosal is the multi-dose vial), or to a previous dose of any influenza vaccine.

Tell the doctor if you/your child has ever experienced Guillain-Barré syndrome (severe muscle weakness) after a previous dose of influenza vaccine. If you notice any other problems or symptoms following vaccination, please contact your health care professional immediately. Vaccination with Fluzone or Fluzone High-Dose vaccine may not protect all individuals.
