What happens if the flu shot is given subcutaneously?
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.
What happens if you get a shot too high on ARM?
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.

What happens if flu shot is given too low?
Some nurses administer too low or towards the back of the arm while some administer too high, near the shoulder joint. In those cases, it is very likely that vaccine is not injected into muscle at all and could possibly cause damage. It is very important that you administer the shot into the very center of the deltoid.
Can an injection hit a nerve?
Post-injection nerve damage can result from direct needle trauma, chemical irritation, toxic action of the injected solution, and neuritis (or fibrotic changes). When a nerve injury is caused by a needle, most patients report immediate pain at the time of injection,11 as our patient did.
Can your arm hurt 2 weeks after a flu shot?
Having a sore arm after getting the flu shot is very normal. The soreness or discomfort typically goes away after a few days.

How long does reaction to the flu shot last?
