Why Is Vivotif So Hard to Find? [Explained for 2026]

You've got a trip coming up to South Asia, sub-Saharan Africa, or Latin America — regions where typhoid fever is a real risk. Your doctor has prescribed Vivotif, the oral typhoid vaccine. But when you call your pharmacy, they don't have it. You call three more. Still nothing. Sound familiar?

Vivotif is a specialty vaccine primarily stocked at travel medicine clinics and select pharmacies — not every corner drugstore carries it. Knowing why it's hard to find, and where to look, can save you valuable time before your departure.

What Is Vivotif and Why Is It a Niche Product?

Vivotif is the brand name for the typhoid vaccine live oral Ty21a — the only oral typhoid vaccine available in the United States. It contains a live, weakened (attenuated) strain of Salmonella typhi bacteria that stimulates your immune system without causing disease. It's approved for adults and children ages 6 and older.

Unlike common prescription drugs taken daily, Vivotif is a four-capsule series taken every other day over one week. It requires refrigeration at 35.6°F–46.6°F at all times. Because of its limited demand — it's not a routine vaccine in the US — pharmacies often don't stock it unless they specialize in travel medicine.

Has Vivotif Been in a Shortage?

Yes. Vivotif experienced a documented shortage that began in December 2020, tracked by the American Society of Health-System Pharmacists (ASHP). The shortage was officially resolved in January 2023 when Emergent Travel Health confirmed availability through wholesalers. Since then, Bavarian Nordic — which acquired the vaccine in May 2023 — has worked to expand distribution.

As of 2026, there is no active FDA shortage of Vivotif. Revenue from the vaccine grew 30% in Q3 2025 year-over-year, and Vivotif has captured a 20% US market share in typhoid vaccines. That's good news — but it doesn't mean every pharmacy has it on the shelf.

Why Can't I Find Vivotif at My Regular Pharmacy?

Even without an active national shortage, Vivotif can be hard to find at an everyday pharmacy for several reasons:

Low demand at general pharmacies. Typhoid vaccination isn't part of the routine US immunization schedule, so chains like Walgreens or CVS may not stock it at all locations.

Cold-chain requirements. Vivotif must stay refrigerated continuously. Not all pharmacies maintain dedicated cold-chain vaccine storage for low-volume products.

Seasonal demand spikes. Travel to high-risk regions peaks in summer and around the holidays. Pharmacies that do stock Vivotif may run out during those windows.

Specialty distribution. Vivotif is primarily stocked by travel medicine clinics, airport pharmacies, and specialty vaccine distributors — not general wholesalers.

Where Are You Most Likely to Find Vivotif in Stock?

The best places to find Vivotif are:

Travel medicine clinics (these are the most reliable source — they specialize in vaccines for international travelers)

CVS MinuteClinic locations (prescription required)

Walgreens and Rite Aid locations that carry travel vaccines

University or hospital-affiliated travel health clinics

International traveler health centers (CDC-affiliated)

Calling ahead is essential. Even at travel clinics, inventory can fluctuate. Give yourself at least two to three weeks before departure to secure your vaccine.

How Much Time Do You Need to Start Vivotif Before Travel?

Vivotif requires some planning. The four-capsule series is taken on Days 1, 3, 5, and 7, and you must complete all four doses at least one week before potential exposure to S. typhi. That means you need at least eight days from your first dose before you can be considered vaccinated.

Factor in time to find the vaccine, obtain a prescription, and allow the series to complete. Aim to start the process three to four weeks before your trip.

What If You're on Antibiotics or Antimalarials?

This is a common and important issue. Because Vivotif contains live bacteria, antibiotics and sulfonamides taken at the same time can kill the vaccine bacteria before they trigger an immune response. You should not take Vivotif while on antibiotic therapy — wait until your antibiotic course is complete.

The antimalarial drug proguanil (found in Malarone/atovaquone-proguanil) can also interfere with Vivotif's effectiveness. If you're using Malarone for malaria prevention, make sure at least 10 days have passed after your last Vivotif dose before starting proguanil.
