Us Citizens: Yellow Fever Vaccine For Bolivia?

If you're a US citizen planning to travel to Bolivia, it's important to be aware of the health risks and recommended vaccinations. While the CDC and WHO suggest several vaccinations for travellers to Bolivia, including typhoid, hepatitis A, polio, and rabies, one of the key considerations is the yellow fever vaccine.

Yellow fever is a potentially fatal virus spread by mosquitoes, primarily found east of the Andes in Bolivia. So, do US citizens need the yellow fever vaccine to enter Bolivia?

The answer is, it depends on your travel plans. The CDC recommends the yellow fever vaccine for travellers over 9 months old who are going to areas below 7,500 feet in elevation east of the Andes. This includes certain departments and designated areas within other departments. However, it is not recommended for travel limited to areas above this elevation, such as the cities of La Paz and Sucre. Additionally, Bolivia requires proof of yellow fever vaccination if you are arriving from a country with the virus.

Therefore, it is essential to review the specific regions you plan to visit in Bolivia and consult with a healthcare professional to determine if the yellow fever vaccine is necessary for your trip.

Do US citizens need a yellow fever vaccine if they are arriving from a country with no risk of yellow fever transmission?

According to the Centers for Disease Control and Prevention (CDC), a yellow fever vaccine is required for US citizens arriving in Bolivia from a country with a risk of yellow fever transmission. The vaccine is recommended for all travellers over nine months of age who will be travelling east of the Andes at altitudes under 7,500 feet (2,286 meters). This includes the departments of Beni, Pando, Santa Cruz, Cochabamba, La Paz, and Tarija.

However, the vaccine is not recommended for regions under 2,300 meters (7,500 feet) in elevation. Additionally, some countries may have specific requirements for entry regarding proof of yellow fever vaccination. It is important to check with the relevant consulate or embassy to confirm the requirements for the country you are travelling to.

The CDC also recommends that all eligible travellers should be up to date with their COVID-19 vaccines before travelling to Bolivia. Other recommended vaccines for Bolivia include typhoid, hepatitis A, polio, chikungunya, rabies, hepatitis B, influenza, COVID-19, pneumonia, meningitis, chickenpox, shingles, Tdap (tetanus, diphtheria, and pertussis), and measles, mumps, and rubella (MMR).

What are the entry requirements for proof of yellow fever vaccination?

The International Certificate of Vaccination or Prophylaxis (ICVP), also referred to as the "yellow card," is the official document that serves as proof of vaccination against yellow fever. This certificate is required by some countries as a public health measure to prevent travellers from importing the virus. It is important to note that the requirements for this proof of vaccination may vary depending on the country of entry.

• The ICVP must be presented along with the traveller's passport. It serves as proof that the individual has been vaccinated against yellow fever.
• The ICVP must be the original copy, signed and stamped. Photocopies or screenshots are not accepted.
• The ICVP becomes valid 10 days after receiving the yellow fever vaccine. This is because it takes time for the body to develop immunity to the yellow fever virus.
• A single dose of the yellow fever vaccine typically provides lifetime protection. However, some countries may require proof of vaccination within the last 10 years for entry. It is important to check the specific requirements for your destination.
• The yellow fever vaccine is recommended for anyone travelling to a region where the virus is present. However, infants under nine months and individuals over 60 years old should consult a healthcare provider before vaccination.
• If an individual has a medical condition or allergy that contraindicates the yellow fever vaccine, they may need to obtain a medical waiver from a healthcare provider. This waiver should be presented along with the ICVP when entering a country that requires proof of vaccination.
• The yellow fever vaccine is available at designated Yellow Fever Vaccination Centres. After receiving the vaccine, individuals will be provided with the ICVP as proof of vaccination.
• In addition to the ICVP, it is essential to take precautions to prevent mosquito bites, as yellow fever is spread through mosquito bites. This includes using insect repellents, wearing protective clothing, and staying in accommodations with window screens or air conditioning.

What are the CDC's yellow fever vaccine recommendations for US citizens travelling to Bolivia?

The CDC recommends that US citizens get vaccinated against yellow fever before travelling to Bolivia if they are aged 9 months or older and are going to areas below 2,300 m (7,550 ft) in elevation, east of the Andes Mountains. This includes the entire departments of Beni, Pando, Santa Cruz, and designated areas in the departments of Chuquisaca, Cochabamba, La Paz, and Tarija.

The CDC does not recommend the vaccine for travel limited to areas above 2,300 m (7,550 ft) in elevation, including the cities of La Paz and Sucre.

Yellow fever is a potentially fatal virus spread by mosquitoes. It is mainly found in rural areas of affected countries but can also occur in urban areas. The vaccine provides lifetime protection, and a completed International Certificate of Vaccination or Prophylaxis is valid for the lifetime of the vaccinee.

In addition to the yellow fever vaccine, the CDC recommends that travellers to Bolivia be up to date on all routine vaccines, including chickenpox (varicella), diphtheria-tetanus-pertussis (Tdap), and measles-mumps-rubella (MMR). The CDC also recommends that all eligible travellers be up to date with their COVID-19 vaccines.

Other vaccines that may be considered for travel to Bolivia include hepatitis A, hepatitis B, rabies, and typhoid.

What is the duration of protection from the yellow fever vaccine?

The yellow fever vaccine provides long-lasting protection from the disease. The vaccine is highly effective, with the World Health Organization (WHO) stating that it provides immunity within 10 days for 80-100% of people. Furthermore, within 30 days, more than 99% of vaccinated individuals are immune.

The Centers for Disease Control and Prevention (CDC) notes that a single dose of the vaccine offers lifelong protection from the virus. However, the CDC also mentions that some travellers may consider a booster shot if it has been ten years since their last vaccination and they plan to travel to an area with an ongoing outbreak.

The yellow fever vaccine is a live-attenuated vaccine, meaning it uses a weakened form of the yellow fever virus. This allows the body to create a strong and long-lasting immune response from just one dose.

It is important to note that the vaccine is not 100% effective, and there have been rare cases of yellow fever in vaccinated individuals. However, the vast majority of people are protected from the disease after receiving the vaccine.

What are the risks of yellow fever in Bolivia?

Yellow fever is a viral disease transmitted by mosquitoes that bite during the day. The disease is endemic in several Latin American countries, including Bolivia, and is restricted to enzootic regions. The mosquito Aedes aegypti, which spreads the disease, has re-infested most of the areas it previously occupied, increasing the risk of urban fever epidemics.

Yellow fever is a severe illness with a high fatality rate. Death occurs in up to half of those who develop severe disease. The disease has two phases. In the initial phase, symptoms include fever, chills, loss of appetite, nausea, muscle pains, and headaches. In 15% of cases, the disease enters a second, toxic phase, where the fever returns, along with abdominal pain, jaundice, and bleeding from the mouth, nose, eyes, and gastrointestinal tract. This toxic phase is fatal in 20-50% of cases.

In Bolivia, yellow fever is primarily found east of the Andes, in regions under 7,500 feet in elevation. The risk of yellow fever in Bolivia is heightened by the presence of the Aedes aegypti mosquito, which has facilitated urban epidemics in the past. The last urban outbreak in Bolivia occurred in 1999. However, the mosquito has since returned to the urban centers of South America, increasing the risk of new outbreaks.

To mitigate the risk of yellow fever in Bolivia, travelers should get vaccinated and take measures to prevent mosquito bites. The yellow fever vaccine is safe and effective and provides lifetime protection. Avoiding mosquito bites involves wearing long-sleeved shirts and pants, using insect repellents, and staying in buildings with window screens.
