GSK Vaccines Patient Assistance Program Patient Guide: How to Get TWINRIX (Hepatitis A and Hepatitis B (Recombinant) Vaccine) at Low or No Cost

TWINRIX is a combination vaccine that protects against both Hepatitis A and Hepatitis B, two serious liver infections spread through contaminated food, water, or bodily fluids. This guide explains how the GSK Vaccines Patient Assistance Program can provide TWINRIX at no cost to eligible patients who lack insurance coverage for vaccines.[2][3]

About TWINRIX

TWINRIX combines inactivated Hepatitis A virus and recombinant Hepatitis B surface antigen in one shot, offering dual protection in a standard three-dose series (at 0, 1, and 6 months). It's recommended for adults 18+ at risk, including travelers to high-risk areas, those with chronic liver disease, or occupational exposure. Administered intramuscularly by healthcare providers, it prevents acute infections that can lead to chronic liver damage, cirrhosis, or liver cancer. Always consult your doctor to confirm if TWINRIX is right for you—it's not suitable for everyone, such as those with severe allergies to vaccine components.[1][2]

Who Qualifies for the Program?

The GSK Vaccines Patient Assistance Program, managed by the independent GSK Patient Access Programs Foundation, offers free TWINRIX to qualifying U.S. patients. Key eligibility criteria include:

• Age 18 years or older (19+ in some older guidelines, but current info confirms 18+).[2][6]
• U.S. resident (including Puerto Rico, but not eligible if enrolled in or approved for Puerto Rico's Mi Salud plan).[2]
• No third-party coverage for vaccines, meaning uninsured or underinsured without prescription drug coverage.[2][4]
• Household income at or below 250% of the Federal Poverty Level (FPL). Exact dollar thresholds vary by household size and year; check current FPL guidelines via HHS.gov.[program details]

Medicare Part D patients are not eligible for vaccine medicines through this program.[4]

Income Eligibility Breakdown

Eligibility hinges on 250% FPL. Use the table below for 2026 estimates (actuals update annually; verify with program at 1-866-728-4368). For a household of 1, 250% FPL is roughly $37,500; add ~$12,000 per additional member.

Notes: Include all household income sources. Provide proof like tax returns, pay stubs (last 30 days), or benefit statements. Limits based on program details; not guaranteed exact.[program details][1]

Insurance Requirements

You must be uninsured or underinsured with no vaccine coverage. This excludes:

• Those with private insurance covering vaccines.
• Medicare Part D enrollees.[4]
• Medicaid or other government plans covering vaccines.

The program verifies insurance status and may contact your providers or insurers.[1][2] It does not constitute health insurance and won't affect other benefits.[3]

Step-by-Step Application Process

Applications go through your healthcare provider—you cannot apply alone.[2][8]

1. Discuss with your provider: Confirm TWINRIX medical need. Ask them to register at www.gskpatientassistanceprogramportal.com (free, required for prescribers).[1][2][9]
2. Gather documents: Proof of income, residency, no insurance proof. Download forms: English/Spanish application, patient health/allergy form, third-party authorization.[2]
3. Complete application: Provider fills/signs, including shipping address and certification that vaccine is medically indicated.[1][4]
4. Submit: Provider faxes to 1-855-474-3063 or uses online portal. Or call 1-866-728-4368 for mail request (M-F 8am-8pm ET).[2][7]
5. Await approval: If approved, eligible for up to 12 months of vaccine doses.[2][6]

Keep copies; originals not returned.[4] Assistance in Spanish/multiple languages.[2]

Timeline and Delivery

Processing time not specified, but aim for approval before administration to avoid delays.[6][7] Once approved, vaccines ship directly to your provider's office for administration—no home delivery.[program details][1] Subsequent doses need a Vaccine Dose Authorization Request Form (DARF), faxed/approved prior.[2][7] Full series possible within 12 months; reauthorization required annually.[6]
