What Is the Difference Between Twinrix and Hepatitis A or B Vaccines?

Protecting yourself against hepatitis is a crucial step when preparing for international travel. At Ocean Travel Clinic in Vancouver, we're often asked, "What's the difference between Twinrix and the separate Hepatitis A or B vaccines?" Here's a quick guide to help you understand your options and make the best decision for your travel health.

Hepatitis A and B: What's the Risk?

• Hepatitis A is commonly spread through contaminated food or water, especially in destinations like Mexico, the Caribbean, South America, Africa, and Asia.

• Hepatitis B is transmitted through blood and bodily fluids. It can be contracted through medical procedures, unprotected sex, or even piercings or tattoos done abroad.

Twinrix vs. Hepatitis A or B Vaccines

Twinrix: protects against Hepatitis A & B, needs three doses (over 6 months) or an accelerated 4-dose option and is ideal for combined protection

Hepatitis A Only: Hepatitis A, two doses (6 months apart), Good for food/water safety

Hepatitis B Only: Hepatitis B, three doses (over 6 months), Important for healthcare workers or long-term travellers

Why Choose Twinrix?

Twinrix is a convenient and efficient choice if you're at risk for both infections, which is often the case when travelling to high-risk areas. It combines the protection of two vaccines in one series, reducing the number of injections.

When to Get Vaccinated

Ideally, visit us at least 4–6 weeks before travel, but we can also offer accelerated schedules for last-minute trips.
