Yellow fever is a serious viral disease transmitted by infected mosquitoes, primarily found in tropical regions of Africa and South America. It poses a significant health risk due to its potential to cause severe illness and even death if left untreated.
However, thanks to advancements in medical science, one of the most effective ways to prevent yellow fever is through vaccination. The yellow fever vaccine has been instrumental in reducing the incidence of this disease worldwide, especially in endemic areas.
But what exactly is the name of the yellow fever vaccine, and what should you know about it? Understanding the vaccine’s name, its origins, and how it works can help demystify the process and encourage more people to get vaccinated.
Whether you are planning to travel to at-risk regions or simply want to expand your knowledge about vaccines, learning about the yellow fever vaccine is both timely and important.
The Official Name of the Yellow Fever Vaccine
The yellow fever vaccine is officially known as YF-Vax in the United States, while globally, the most widely used yellow fever vaccine is called 17D. These vaccines are live-attenuated, meaning they contain a weakened form of the virus that stimulates immunity without causing the disease.
The name 17D originates from the specific strain of the yellow fever virus used in the vaccine, which was developed in the 1930s by Max Theiler, who later won a Nobel Prize for this groundbreaking work.
YF-Vax is a commercial name for the vaccine based on this strain, manufactured and distributed by licensed pharmaceutical companies.
Several other brand names exist internationally, but 17D remains the cornerstone of yellow fever vaccination worldwide, supported by decades of research and proven safety.
“The 17D yellow fever vaccine remains one of the most effective vaccines ever developed, saving millions of lives globally.” – World Health Organization
Different Yellow Fever Vaccine Names Worldwide
- YF-Vax: The licensed vaccine in the United States.
- Stamaril: Used in many countries outside the U.S.
- 17DD: A variation used predominantly in Brazil.
- 17D-204: Another variant commonly used in Europe and Africa.
How the Yellow Fever Vaccine Works
The yellow fever vaccine works by introducing a weakened virus to the body’s immune system, prompting it to build defenses without causing illness. This immune response prepares the body to fight the actual yellow fever virus if exposed in the future.
Because the vaccine uses a live-attenuated virus, it stimulates both humoral (antibody-mediated) and cellular immunity, creating long-lasting protection. Most people develop immunity within 10 days of vaccination, and for many, protection can last a lifetime.
Vaccination is especially critical for travelers heading to endemic areas or individuals living in regions prone to outbreaks. It not only protects the individual but also helps prevent the spread of the virus.
| Mechanism | Description |
| Live-attenuated virus | Weakened yellow fever virus strain used to trigger immune response |
| Immune system activation | Stimulates production of neutralizing antibodies and T-cell response |
| Duration of immunity | Typically lifelong after a single dose, though boosters may be required in some cases |
Who Should Receive the Yellow Fever Vaccine?
The yellow fever vaccine is recommended for anyone living in or traveling to regions where yellow fever is endemic or where outbreaks have occurred. This includes parts of Africa, Central and South America, and some Caribbean countries.
Vaccination is mandatory for entry into certain countries, and travelers may be required to show proof of vaccination through an International Certificate of Vaccination or Prophylaxis (ICVP), often called the “yellow card.”
Some groups, however, should exercise caution or avoid the vaccine due to potential side effects. These include infants under 6 months, pregnant women (unless travel is unavoidable), people with severe allergies to vaccine components, and those with compromised immune systems.
- Travelers to endemic areas
- Residents of at-risk countries
- Healthcare and laboratory workers exposed to yellow fever virus
- People attending mass gatherings in endemic regions
Travel and Vaccination Requirements
International health regulations often require proof of yellow fever vaccination for travelers entering certain countries.
Failure to provide this proof can result in denial of entry or mandatory quarantine. It is therefore essential to plan vaccination well in advance of travel and carry your vaccination certificate at all times.

Safety and Side Effects of the Yellow Fever Vaccine
Overall, the yellow fever vaccine is considered safe and effective, with millions of doses administered worldwide each year. Most side effects are mild and temporary, including soreness at the injection site, mild fever, and muscle aches.
Serious adverse reactions are rare but can occur, especially in older adults or those with weakened immune systems. These may include allergic reactions, neurological complications, or viscerotropic disease, which mimics severe yellow fever illness.
Due to these risks, healthcare providers carefully screen candidates before vaccination and advise on contraindications. The benefits of vaccination, however, generally far outweigh the risks for people at risk of exposure.
“Vaccination with the yellow fever vaccine remains the best protection against this deadly disease, with safety profiles that support its widespread use.” – Centers for Disease Control and Prevention
- Mild side effects: headache, muscle pain, fever, injection site soreness
- Severe side effects: allergic reactions, neurological complications (extremely rare)
- Pre-vaccination screening is essential
History and Development of the Yellow Fever Vaccine
The yellow fever vaccine has a rich history dating back to the 1930s when Max Theiler developed the 17D strain. This development marked a turning point in controlling yellow fever, which had caused devastating epidemics for centuries.
Theiler’s work earned him the Nobel Prize in Physiology or Medicine in 1951, recognizing the vaccine’s profound impact on public health. Since then, the vaccine has undergone various improvements and adaptations to meet global demand.
Mass vaccination campaigns have been instrumental in preventing outbreaks and eliminating yellow fever in certain regions, showcasing the vaccine’s enduring legacy.
| Year | Event |
| 1937 | Development of the 17D vaccine strain by Max Theiler |
| 1951 | Theiler awarded Nobel Prize for vaccine development |
| 1960s | Widespread use of vaccine in endemic regions begins |
| Present | Ongoing global vaccination campaigns and research |
Storage and Administration of the Yellow Fever Vaccine
Proper storage and handling of the yellow fever vaccine are critical to maintaining its effectiveness. The vaccine must be stored at a temperature between 2°C and 8°C (36°F to 46°F) and protected from light.
Once reconstituted, the vaccine should be used within a short period, usually six hours, to ensure potency. This requires careful planning by healthcare providers during vaccination campaigns.
The vaccine is administered as a single subcutaneous injection, typically in the upper arm. A single dose generally confers lifelong immunity, though some countries recommend boosters every 10 years for continued protection.
- Store refrigerated at 2°C–8°C
- Protect from light and use quickly after preparation
- Administered as a single subcutaneous dose
- Booster doses may be required for some travelers
Yellow Fever Vaccine and Global Health Initiatives
The yellow fever vaccine plays a vital role in global health, especially in tropical regions where outbreaks can cause significant mortality. International organizations like the World Health Organization (WHO) and UNICEF support vaccination campaigns to increase coverage and prevent epidemics.
Efforts to improve vaccine availability and affordability continue, addressing challenges such as vaccine shortages and distribution in remote areas. These initiatives aim to reduce the global burden of yellow fever and protect vulnerable populations.
Vaccination also contributes to strengthening health systems and increasing awareness of vector control methods, complementing other disease prevention strategies.
