Shoulder Injury Related to Vaccine Administration (SIRVA)

As vaccination efforts continue worldwide, it’s crucial to understand potential risks associated with the process. While vaccines are generally safe and effective, there are instances where individuals may experience adverse reactions, including Shoulder Injury Related to Vaccine Administration (SIRVA). In this article, we delve into what SIRVA is, its symptoms, causes, and the legal avenues available for those affected.

What is SIRVA?

SIRVA is a relatively uncommon but potentially severe adverse reaction that can occur following vaccination. It involves inflammation of the shoulder structures, including the tendons, bursae, and ligaments, typically resulting from improper vaccine administration.

Symptoms of SIRVA

The symptoms of SIRVA can vary but often include:

  • Intense shoulder pain: Persistent, sharp pain at the injection site that may radiate down the arm.
  • Limited range of motion: Difficulty moving the shoulder or lifting the arm.
  • Swelling and inflammation: Visible swelling or redness around the injection site.
  • Weakness or numbness: Sensations of weakness or numbness in the affected arm.

It’s essential to seek medical attention if you experience any of these symptoms following vaccination.

Causes of SIRVA

SIRVA typically occurs when a vaccine is injected too high or too deeply into the shoulder, inadvertently affecting the underlying structures. Common causes of SIRVA include:

  • Incorrect injection technique: Vaccines should be administered into the deltoid muscle of the shoulder, avoiding nearby structures.
  • Needle length: Using a needle that is too long can penetrate deeper than necessary, increasing the risk of injury.
  • Angle of injection: Injecting the vaccine at the wrong angle can result in trauma to the shoulder tissues.

Legal Recourse for SIRVA

Individuals who experience SIRVA may be entitled to compensation through the National Vaccine Injury Compensation Program (VICP). VICP provides a streamlined process for individuals to seek compensation for vaccine-related injuries, including SIRVA, without the need for traditional litigation.

To pursue a claim for SIRVA through VICP, certain criteria must be met, including:

  • Documented evidence of vaccination and injury.
  • Onset of symptoms within a specified timeframe following vaccination.
  • Comprehensive medical documentation supporting the diagnosis of SIRVA.

Compliance with the statute of limitations for filing a claim.
