Shoulder Injury Related to Vaccine Administration, or “SIRVA,” is an increasingly common and well-recognized vaccine injury.  Understanding more about this…

Research and case studies suggest that SIRVA is caused by improper administration of the vaccine, rather than the vaccine components. It is recommended that injections be administered into the deltoid muscle in the upper arm for adults. However, even trained medical professionals can misjudge the placement of an injection, placing it too high or too deep, outside of the recommended injection site.
