Flu Shot Injury and Workers' Compensation: What You Need to Know

Workers’ compensation coverage for flu shot reactions depends on state law and the circumstances of vaccination.

General Principles

• Compensability requires the injury to arise out of and in the course of employment.
• Ordinary diseases of life (colds, flu) are typically excluded unless employment significantly increased exposure risk.
• Mandatory vs. voluntary: If the employer requires the flu shot as a condition of employment, many states treat resulting injuries as compensable.
• Voluntary shots: Often not covered unless administered on-site during work hours as an employer-sponsored benefit with implicit expectation.

State Variation

• Some states have specific statutes covering vaccine injuries for healthcare workers or first responders.
• Others apply general “positional risk” or “increased risk” doctrines.
• A few exclude all vaccine reactions unless the vaccine itself was defective.

Practical Steps

1. Report any adverse reaction to your employer immediately (in writing).
2. Seek medical care; document the temporal link to the vaccine.
3. File a workers’ comp claim per your state’s deadlines.
4. Consult your state’s Workers’ Compensation Board or an attorney specializing in work injuries.
