Yellow Fever Vaccine
  • Save
Yellow Fever Vaccine
  • For more than 80 years, a safe and efficient yellow fever vaccine is available.
  • For the majority of people, a single dose offers lifetime safety.
  • The vaccine reflects the live, weakened, single-shot type of the virus.
  • The vaccine is recommended for people over 9 months who fly to or live in areas at risk in Africa and South America for the yellow fever virus.
  • The entry into certain countries will require the yellow fever vaccine.

Are you advised to use the yellow fever vaccine?

For individuals 9 months of age and older who fly to or stay in risky areas of yellow fever in Africa and South America. Yellow Fever Vaccine Recommendations

For most people, a single dose of yellow fever protective is given, and no booster is needed. Travelers to areas with active outbreaks should get a booster dose of yellow fever if they have been vaccinated for 10 years or older. Many countries may also need a booster dose of the vaccine. For information about specific country conditions, please see Traveler’s health.

Talk to your doctor to decide that before your ride to a yellow fiber risk area you need yellow fever or a booster shot.

Yellow Fever Vaccine reaction

Some people may be more likely to develop a vaccine reaction, but still benefit from vaccination. Their parents should negotiate the vaccination with their health care providers:

  • 6 to 8 months of age
  • 60 years of age or over
  • Breastfeeding Many individuals should not be immunized.
  • Ages 6 months or younger
  • Organ transplant recipients
  • Malignant tumor diagnosis
  • Diagnosis of thoracic disease related to impaired immune function
  • diagnosis of primary immune deficiency
  • Immunosuppressive and immunomodulatory therapies
  • Diagnosis of signs of immunosuppressive and immunomodulatory therapy
  • Allergic reactions include problems breathing or swallowing (anaphylaxes)
  • swelling of the brain, spine, or surrounding tissues (encephalitis, or meningitis).
  • Guillain-Barré syndrome, an abnormal nervous system disease that damages a person’s own immune system, is rarely seen to cause serious, often life-threatening reactions to the Yellow Fever vaccine.
  • Internal organ failure and insufficiency See your healthcare provider regularly if you have been vaccinated for yellow fever, have nausea, tiredness, aches, cough, or diarrhea.

Some people may be more vulnerable to a vaccine reaction but may still benefit from vaccination.

  • Around 6 and 8 months
  • More than 60 years old
  • Breastfeeding Yellow Fever Vaccination, Pregnancy, and Conception Yellow fever vaccination is provided to many pregnant women without apparent harmful effects on their fetus. These patients, or their parents, must speak with a health care provider about getting vaccinated. The yellow fever vaccine, however, poses a theoretical risk because it is a live virus vaccine.

Pregnant women must stop or postpone their travel to an area where yellow fever is at risk. When you can’t avoid flying, talk to your doctor about vaccination.

While there is likely to be a reasonable two weeks lag between yellow fever vaccinations and birth, a more moderate one-month delay was recommended.

It is very unlikely that a woman will have complications with a vaccine during childbirth and that her child will be born healthy if it occurs for some reason.

An RNA virus belonging to the Flavivirus family is a Yellow Fever Virus. It is related to the West Nile, encephalitis of St. Louis and encephalitis viruses in Japan. Aedes and Homologues type mosquitoes are mainly passed into humans with the yellow fever virus.

Mosquitoes are infected with the virus by feeding (human or not) infected primates and can transmit the virus to other primates (human or non-human). Mosquitos (called “viremic”), fast prior to the onset and up to 5 days after the onset of fever, are infected people with yellow fever virus.

The Yellow Fever Virus has three stages of transmission: woodland, intermediate and urban.

  • The process of the jungle (sylvatic) is the propagation of the virus between non-human (e.g., monkeys) primates and forested mosquitoes. As people visit and work in the jungle, the disease transmits mosquitoes from monkeys to humans.
  • There is an (savannah) intermediate process in Africa involving the transmission of mosquito viruses to humans living or working in jungle boundary zones. During this process, monkey to man, and man to man, the virus can be transmitted by mosquitoes.
  • The transmissions to urban mosquitoes, mainly Aedes aegypti, include the urban process. Typically, a viremic individual who has been infected in the jungle or savanna carries the virus to the urban environment.

Symptoms, Diagnosis, & Treatment

Most individuals infected with yellow fever either have no symptoms or mild symptoms.

The period from infection to illness is generally 3 to 6 days for people who develop symptoms.

Due to the risk of severe illness, everyone who has symptoms of yellow fever should see their care provider after traveling or living in an area at risk of the disease. You will likely be safe from potential infections once you have been infected.


Some people become affected with yellow fever with their initial symptoms, including:

  • Sudden beginning of fever
  • Chills
  • Severe headache
  • Back pain or aches
  • Body general
  • Nausea
  • Vomiting
  • Fatigue (feeling tired)
  • Fatigue or Weakness.
  • Weakness and tiredness (feeling tired) could last many months for some people who recover.

Many people are going to develop a more severe disease type.

A brief recovery (a period you feel better), which could last just a few hours or one day, will be followed by an increasingly severe illness in 1 out of 7 people with initial symptoms.

Serious disease of yellow and white fevers may result in dangerous symptoms, such as high fever, yellow (jaundice), vomiting, and shock or organ failure. See a healthcare provider straight away should you experience any of these signs. 30-60 percent die from those with severe disease.


  • A laboratory testing, a person’s symptoms, and travel history are used to diagnose a Yellow Fever infection.
  • For Healthcare Providers they provide further data on diagnostic testing.


  • No drug is available to treat or cure yellow fever infections.
  • Rest, drink water, and use pain relievers and medicine for temperature control and relief of discomfort.
  • Avoid other pharmaceutical items such as aspirins or other non-steroids that may increase the risk of bleeding, for example, ibuprofen (Advil), Motrin and naproxen (Aleve).
  • For close observation and medical care, persons with serious symptoms of yellow fever infection should be hospitalized.

Protection from mosquito bites for up to 5 days after symptoms start if after traveling you have symptoms of yellow fever (usually around a week following a bite of an infected mosquito. This stops yellow fever from spreading to uninfected mosquitos that can spread the virus to others.
