The pain elicited by administering immunizations can be a
significant cause of anxiety and fear in many patients. This apprehension can be
one reason a person may decline immunizations and can impair the clinician’s
ability to perform an examination. This project uses a mechanical device,
ShotBlocker™, to apply local pressure to an injection site at the time of needle
penetration, thereby stimulating afferent fibers to reduce pain sensation.
