You should not receive this vaccine if you have ever had a life-threatening allergic reaction to a yellow fever vaccine, or if you have:
- a chronic disease such as asthma or other breathing disorder, diabetes, kidney disease, or blood cell disorders such as anemia;
- a weak immune system caused by disease (such as cancer, HIV, or AIDS), or by taking certain medicines such as steroids;
- if someone in your household has a weak immune system; or
- if you are allergic to eggs or egg products;
Before receiving this vaccine, tell the doctor if you are allergic to any foods or drugs, or if you have:
- a history of seizures;
- an allergy to latex rubber;
- a neurologic disorder or disease affecting the brain (or if this was a reaction to a previous vaccine); or
- a weak immune system caused by disease, bone marrow transplant, or by using certain medicines or receiving cancer treatments.
You can still receive a vaccine if you have a cold or fever. In the case of a more severe illness with a fever or any type of infection, wait until you get better before receiving this vaccine.
Vaccines may be harmful to an unborn baby and generally should not be given to a pregnant woman. However, not vaccinating the mother could be more harmful to the baby if the mother becomes infected with a disease that this vaccine could prevent. Your doctor will decide whether you should receive this vaccine, especially if you have a high risk of infection with yellow fever.
Do not receive this vaccine without telling your doctor if you are breast-feeding a baby.
Children younger than 9 months old should not receive this vaccine, and should not travel to areas where yellow fever is known to exist.
How is this vaccine given (Yf-Vax)?
This vaccine is given as an injection (shot) under the skin. You will receive this injection in a doctor's office or other clinic setting.
The yellow fever vaccine is given every 10 years to people who are at risk of exposure to yellow fever. The first shot can be given to a child who is at least 9 months old. Your individual booster schedule may be different from these guidelines. Follow your doctor's instructions or the schedule recommended by your local health department or the Centers for Disease Control and Prevention (CDC).
In addition to receiving the yellow vaccine, use protective clothing, insect repellents, and mosquito netting around your bed to further prevent mosquito bites that could infect you with the yellow fever virus.
If you continue to travel or live in areas where yellow fever is common, you should receive a booster dose of yellow fever vaccine every 10 years.
After receiving the vaccine, you will be given an International Certificate of Verification (yellow card) from the office or clinic where you receive you yellow fever vaccine. This certificate should contain the date you received the vaccine, as well as the vaccine's lot number and manufacturer. You will need this card as proof of vaccination to enter certain countries. This card becomes valid 10 days after you receive the vaccination and remains valid for 10 years.
Your doctor may recommend treating fever and pain with an aspirin-free pain reliever such as acetaminophen (Tylenol) or ibuprofen (Motrin, Advil, and others) when the shot is given and for the next 24 hours. Follow the label directions or your doctor's instructions about how much of this medicine to take.
It is especially important to prevent fever from occurring if you have a seizure disorder such as epilepsy.
