What are the risks from Yellow Fever vaccine?
A vaccine, like any medicine, is capable of causing serious problems, such as severe allergic reactions. The risk of a vaccine causing serious harm, or death, is extremely small.
Reactions are less likely to occur after a booster dose of yellow fever vaccine than after the first dose.
Mild problems:
soreness, redness, or swelling where the shot was given, fever, aches.
If these problems occur, they usually begin soon after the shot and last for 5 to 10 days. In studies, they occurred in as many as 25 percent of vaccine recipients.
Severe problems (estimates based on passive reporting):
Life-threatening allergic reaction (approximately 1 reported per 131,000 doses).
Severe nervous system reactions (approximately 1 reported per 150,000 to 250,000 doses).
Life-threatening severe illness with major organ system failure (approximately 1 reported per 200,000 to 300,000 doses, or 1 reported per 40,000 to 50,000 doses in people 60 years of age and older). More than half of the people who suffer these side effects die.
For persons of all ages for whom vaccination is indicated, a
single subcutaneous injection of 0.5 mL of reconstituted vaccine
is used. Generally, a subcutaneous injection in an adult is given in the fatty tissue in the back of the upper arm...
Booster doses: The International Health Regulations require revaccination at intervals of 10 years. Revaccination can boost antibody titer; however, evidence from multiple studies (20–23) demonstrates that yellow fever vaccine immunity persists for 30–
35 years and probably for life.
