As detailed in prior entries, shoulder injuries can occur as a result of receiving a flu shot, Tdap, or other vaccination. Typically, these injuries are caused from improper needle placement by the person or provider administering the shot. However, in rare instances, the use of an improper gauge or length needle can also cause injury due to over penetration. The flu shot and other vaccines are designed to be injected just into the surface of the muscle. Any shot given too deep into the muscle tissue or surrounding anatomy can cause injury.
The decision by providers regarding which size needle to use for a shot is based upon the following factors: age of the recipient; body mass of the recipient; the anatomic site of administration; and whether it is supposed to be administered intramuscularly or subcutaneously.
