Can You Sue Vaccine Companies? The Shield, VICP, and Exceptions

For almost every vaccine on the U.S. childhood and adult schedule, you cannot sue the manufacturer in the ordinary sense. Federal law routes vaccine-injury claims into a no-fault government program, and a traditional civil lawsuit against a vaccine company is available only in a few narrow situations, most of them only after the government program has finished with your case. So the practical answer to whether you can sue vaccine companies is: rarely, and almost never as your first move.

The Federal Shield on Vaccine Manufacturers

The reason a lawsuit isn’t the starting point is the National Childhood Vaccine Injury Act of 1986. Congress passed it after a wave of personal-injury suits threatened to push manufacturers out of the vaccine market, and it built a trade: manufacturers pay an excise tax into a compensation trust, and injured people go through an administrative program rather than into court.¹

Under 42 U.S.C. § 300aa-22, a manufacturer is not liable for injuries caused by unavoidable side effects, provided the vaccine was properly manufactured and came with adequate warnings.² The Supreme Court hardened that shield in 2011. In Bruesewitz v. Wyeth LLC, the Court held that the NCVIA preempts all design-defect claims against vaccine manufacturers, reasoning that allowing such suits would undermine the compensation system Congress built.³ A manufacturer also cannot be held liable solely for failing to warn the patient directly, because warnings flow through the healthcare provider who administers the shot.

What that leaves for civil court is a small opening. The statute protects the manufacturer only when the vaccine “was properly prepared,” so a claim that a specific batch was contaminated, mishandled, or otherwise botched in production is not preempted.² In practice manufacturing defects are rare and expensive to prove, which is why this exception is narrow rather than a workaround.

Where You Have To Go Instead: The Vaccine Injury Compensation Program

If a covered vaccine injured you, your first filing is a petition with the National Vaccine Injury Compensation Program (VICP), not a complaint in state or federal court. People in the field call it “Vaccine Court,” though it sits inside the U.S. Court of Federal Claims and is decided by Special Masters rather than a jury.⁴⁵

The money doesn’t come out of the manufacturer’s pocket at the individual level. It comes from the Vaccine Injury Compensation Trust Fund, which is funded by a $0.75 federal excise tax on each disease a vaccine dose prevents. A single-disease vaccine such as the flu shot is taxed $0.75; MMR, which covers three diseases, is taxed $2.25.¹⁶ That funding structure is why the VICP replaces a lawsuit rather than sitting alongside one: Congress built it as the substitute.

Covered vaccines are those the CDC recommends for routine administration to children or pregnant women and to which the federal excise tax applies. That takes in most of the standard childhood and adult schedule: MMR, DTaP and Tdap, seasonal influenza, hepatitis A and B, polio (IPV), varicella, HPV, and the pneumococcal and meningococcal vaccines, among others.⁷ Vaccines outside that list, including certain travel vaccines, are not routed through the VICP.

When a Civil Lawsuit Is Actually Available

There are three realistic paths into a traditional civil court against a vaccine manufacturer.

The Vaccine Isn’t on the VICP’s Covered List

If the vaccine that injured you isn’t covered by the VICP, the NCVIA’s restrictions don’t apply to your case. You bring an ordinary personal-injury or product-liability suit. Travel vaccines not recommended by the CDC for routine use in children or pregnant women are the most common example.

You Can Show a Manufacturing Defect

Because the shield in § 300aa-22 protects the manufacturer only when the vaccine “was properly prepared,” a claim that a specific dose was contaminated, improperly stored, or otherwise defective in its actual production can proceed in civil court.² After Bruesewitz, this is essentially the only viable theory left for suing a manufacturer directly, because design-defect claims are preempted and failure-to-warn claims against the manufacturer face the same wall.³

You Reject the VICP’s Judgment

After the VICP process concludes, you have 90 days to reject the decision and file a civil suit instead.⁸ Miss the window and you are deemed to have accepted the outcome. Rejecting the judgment is legal but costly: you lose the no-fault framework, you lose the presumption of causation the VICP gives for injuries on its Vaccine Injury Table, and you lose the program’s attorney-fee protections. What’s left in court is largely a manufacturing-defect theory, because design-defect claims are already off the table.³ Most people who prevail in the VICP accept the award rather than restart in a forum that has already been narrowed against them.

COVID-19 Vaccines Are Not on This Track

A common assumption worth correcting: COVID-19 vaccines are not covered by the VICP, and the analysis above does not apply to them. They fall under the Countermeasures Injury Compensation Program (CICP), activated through the Public Readiness and Emergency Preparedness (PREP) Act. The PREP Act declaration for COVID-19 countermeasures remains in effect even though the public health emergency has ended.⁹¹⁰

The CICP is considerably less generous and less claimant-friendly than the VICP:¹¹

The filing deadline is one year from the date you received the countermeasure, versus three years under the VICP.
The program does not pay your attorney’s fees or costs.
Review is administrative and on paper; there is no judicial hearing.
You can request one administrative reconsideration, but you cannot appeal to a court.
Compensation covers unreimbursed medical expenses, lost employment income, and a survivor death benefit; there is no award for pain and suffering.¹²

The program’s record shows how hard the door is to get through. As of March 2026, more than 14,000 COVID-19 claims had been filed with the CICP. Of roughly 6,800 decided claims, only 95 were found eligible for compensation, and only 44 of those had actually been paid. More than 2,500 were denied for missing the filing deadline, and another 2,500 for not submitting requested medical records.¹³ Suing a COVID-19 vaccine manufacturer directly is not an available substitute; the PREP Act provides its own liability protections, which is why the CICP exists in the first place.

The Deadlines That Decide Everything

Whether any of this is available to you depends on filing on time. For a VICP injury claim, the deadline is three years from the date the first symptom of the injury appeared. For a death claim, it’s two years from the date of death. When HHS adds a new vaccine or condition to the Vaccine Injury Table, a separate window opens for claims tied to that change. For the CICP, the deadline is one year from receiving the countermeasure. These deadlines are strict, and missing them ends the claim regardless of its merits. If you think a vaccine caused a serious injury, the calendar is the first thing to check, before you decide whether you’re filing a petition or, in one of the narrow situations above, a lawsuit.
