What Are the Common Side Effects of Yellow Fever Injections?
Yellow fever injections have similar side effects to other vaccines. Most people with side effects only experience mild discomfort: the site of the shot may become sore, bruised, and swollen; there may also be a mild fever accompanied by achiness and chills. The few people who do have severe symptoms may experience difficulty breathing, behavioral changes, seizures, high fever, irregular heartbeat, hives, and other symptoms that need immediate medical treatment. Side effects of yellow fever injections usually occur within the first hour after a shot is given, but they can also develop within 30 days after the injection.
