What happens if flu shot given subcutaneous?
Injecting a vaccine into the layer of subcutaneous fat, where poor vascularity may result in slow mobilisation and processing of antigen, is a cause of vaccine failure1—for example in hepatitis B,2 rabies, and influenza vaccines.
Is flu shot intradermal or intramuscular?
Influenza virus vaccine should not be given via intravenous administration or subcutaneous administration, it is for intramuscular (IM) administration only, with the exception of the intradermal Fluzone products. All other formulations should not be given by intradermal administration.
What would happen if an intramuscular vaccine is administered too high?
When the injection is given too high or too deep in this muscle, the needle can hit bone or puncture the fluid-filled sac called the bursa, which protects the tendons in the shoulder. When this happens, the bursa, tendons and ligaments can become inflamed.
Is there an intradermal flu vaccine?
Fluzone Intradermal vaccine was recently approved by the FDA as the first intradermal flu vaccine in the United States. The needle is very thin (only 1.5 mm long) and only penetrates the skin, unlike the traditional vaccine that is given intramuscularly.
What can go wrong with an intramuscular injection?
The microbes in injection substances, injection equipment or already-existing on the skin, can enter the body causing very serious infections. Similarly, incorrect injection techniques or erroneous injection locations, can cause blood vessel breakage, muscle or nerve damage and paralysis.
Is the flu vaccine given intramuscular?
The amount of inactivated (injectable) vaccine that should be administered intramuscularly is based on the patient’s age and the vaccine product you are using. For children 6–35 months of age, the correct dosage (volume) is: 0.25 mL for Afluria Quadrivalent. 0.5 mL for Fluarix Quadrivalent.
