If you developed shoulder pain and limited movement after a seasonal influenza vaccination, you may be wondering whether the injury could qualify as Shoulder Injury Related to Vaccine Administration, commonly called SIRVA.

SIRVA claims may be filed through the National Vaccine Injury Compensation Program, or VICP. However, proving a claim requires more than showing that your shoulder became sore after a flu shot. You must provide evidence addressing the Vaccine Injury Table, your medical diagnosis, the timing of your symptoms, your prior shoulder history, and the duration of your injury.

Our Vaccine Act Lawyers can help you understand the requirements, organize your records, and evaluate whether a VICP claim may be appropriate.

What Is SIRVA After a Flu Shot?

SIRVA is a musculoskeletal shoulder injury associated with the administration of an intramuscular vaccine in the upper arm. Under the federal regulation at 42 C.F.R. § 100.3, SIRVA may involve shoulder pain and reduced range of motion caused by an injection reaching or irritating structures in and around the shoulder, such as the bursa, tendons, or ligaments.

SIRVA is different from a short period of ordinary injection-site soreness. Mild tenderness, redness, or aching that improves within a few days usually does not establish a compensable SIRVA injury.

A SIRVA claim generally involves more significant symptoms, such as:

• Persistent shoulder pain.
• Limited ability to raise or rotate the arm.
• Shoulder stiffness or weakness.
• Bursitis, tendonitis, adhesive capsulitis, or another diagnosed shoulder condition.
• Difficulty dressing, sleeping, working, driving, or performing household activities.
• Ongoing need for medication, physical therapy, injections, or surgery.

A diagnosis alone does not guarantee that a claim will qualify. The evidence must also satisfy the legal requirements of the VICP.

The Vaccine Injury Table Requirements for Flu-Shot SIRVA

Seasonal influenza vaccines are included in the Vaccine Injury Table. For a Table SIRVA claim, the first symptom or manifestation must occur within 48 hours after vaccination.

The regulation identifies several requirements. You generally must show all of the following:

1. You received a covered seasonal influenza vaccine

The vaccination must be documented, and the vaccine must generally have been administered in the United States or a qualifying territory.

A vaccination record may identify the date, vaccine type, manufacturer, lot number, provider, and injection site. Not every record identifies the arm. If the injection site is missing, other evidence may become important, including provider testimony, contemporaneous notes, or your own consistent account.

2. Your shoulder symptoms began within 48 hours

The first symptom or manifestation of SIRVA must occur within the applicable Table period. For seasonal influenza vaccine SIRVA, that period is 48 hours.

The most useful records clearly state when the pain began. For example, a medical note may document that pain started the same day as the vaccination or the following morning. Your account may also be relevant, but the timing should remain consistent across medical records, affidavits, and testimony.

3. The affected shoulder is the shoulder that received the injection

The regulation requires pain and reduced range of motion to be limited to the shoulder where the vaccine was administered.

This makes the injection-site evidence important. If the records show a left-arm injection but your symptoms consistently involve the right shoulder, the claim may face a significant issue. If the injection site was not recorded, you should preserve every available source of information about which arm received the flu shot.

4. There was no prior shoulder problem that explains the injury

The regulation addresses prior pain, inflammation, or dysfunction in the affected shoulder. A prior shoulder condition does not automatically prevent a claim, but it may make the medical and legal analysis more complicated.

Medical records from before the vaccination can help establish your baseline. Records showing that you were using the shoulder normally, had no recent complaints, or had no treatment for that shoulder may be useful.

5. No other condition explains your symptoms

SIRVA is a musculoskeletal injury. The regulation states that neurological abnormalities, including findings associated with radiculopathy, brachial neuritis, mononeuropathy, or another neuropathy, would not support a SIRVA diagnosis.

A complete evaluation may need to distinguish SIRVA from a neck injury, nerve condition, traumatic shoulder injury, degenerative disease, or another medical problem.

Why Medical Documentation Matters

The U.S. Court of Federal Claims and its Office of Special Masters consider the entire medical record. Early, consistent documentation often provides the clearest evidence of when symptoms began and how they progressed.

You should try to obtain and preserve:

• The vaccination record, including the date, type of vaccine, and injection site if available.
• Primary-care, urgent-care, emergency-room, and specialist records.
• Medical records from before vaccination showing your shoulder history.
• Physical examination findings, including range-of-motion measurements.
• X-rays, ultrasound reports, MRI reports, and other imaging.
• Physical therapy records.
• Medication records and injection records.
• Orthopedic, physiatry, rheumatology, or neurology evaluations.
• Records concerning any later injury, sports activity, workplace event, or accident.

Imaging can help identify the condition affecting the shoulder. It does not always prove how the injury occurred. A medical provider or qualified expert may need to explain why the findings are consistent with SIRVA and why another condition is less likely.

The Six-Month Requirement and Other Severity Rules

A VICP claim generally must satisfy a separate statutory requirement in addition to the Vaccine Injury Table criteria. Under 42 U.S.C. § 300aa-11, the injury must generally result in residual effects or complications lasting more than six months after vaccination.

This requirement focuses on duration, not merely the intensity of the pain. You may need evidence showing that symptoms, limited movement, or functional problems continued beyond six months from the vaccination date.

The statute also provides alternative ways to satisfy this requirement in certain circumstances, including an injury that resulted in inpatient hospitalization and surgical intervention. These rules are specific, and the facts of each case matter.

On-Table and Off-Table SIRVA Claims

An on-Table claim is one that matches the vaccine, injury, and onset period listed in the Vaccine Injury Table. If you meet the regulatory requirements for SIRVA after a seasonal influenza vaccine, the Table may provide a presumption that the vaccine caused the injury.

The government may still challenge whether the requirements were met. Questions about prior shoulder disease, timing, the injection site, the diagnosis, and alternative causes may become important.

An off-Table claim does not meet one or more Table requirements. For example, symptoms may have begun more than 48 hours after vaccination, or the vaccine may not be listed with SIRVA for the applicable claim. An off-Table claim is not necessarily impossible, but you generally must prove actual causation under the standards applied in Vaccine Court.

Neither an on-Table nor an off-Table theory guarantees eligibility, compensation, or a particular result.

Common Defenses in SIRVA Cases

The Secretary of Health and Human Services may challenge a SIRVA claim based on several issues, including:

• Symptoms did not begin within 48 hours.
• The medical records describe only ordinary injection soreness.
• The injection site or affected shoulder is unclear.
• The petitioner had a preexisting shoulder condition.
• An accident, work activity, or sports injury better explains the symptoms.
• Imaging shows degenerative disease that may account for the condition.
• The symptoms are neurological rather than musculoskeletal.
• The evidence does not show residual effects beyond six months.
• The petition was filed after the applicable deadline.

These issues do not mean that a claim cannot proceed. They indicate areas where careful documentation and medical analysis may be needed.

Filing a SIRVA Claim Through the VICP

A VICP claim begins with a petition filed in the U.S. Court of Federal Claims. The petition should describe the vaccination, the injury, the timing of symptoms, and the basis for compensation. Supporting medical records and affidavits are generally required.

For a nonfatal vaccine injury, the petition generally must be filed within three years after the first symptom or manifestation of the injury. The deadline usually runs from the first symptom, not the date of diagnosis or the date you learned about the VICP.

You can review HRSA's official information about the program and filing process at HRSA's VICP filing guidance. Because filing deadlines can be difficult to calculate, you should consider obtaining legal guidance as soon as possible.

Practical Steps You Can Take Now

If you believe you developed SIRVA after a flu shot, consider taking these steps:

1. Write down the vaccination date, location, vaccine type, and the arm used.
2. Record when you first noticed shoulder pain or restricted movement.
3. Request the vaccination record and all related medical records.
4. Gather records from before the vaccination to document your shoulder history.
5. Follow your healthcare provider's treatment recommendations.
6. Keep a dated record of symptoms and functional limitations.
7. Document any later accident, work event, or activity that could affect the shoulder.
8. Do not delay reviewing the three-year VICP filing deadline.
9. Speak with an attorney who focuses on Vaccine Act matters.
