The vaccine sometimes produces side effects in adults and children. The most common are soreness at the site of the injection, and slight fever, muscle soreness, and fatigue. These side effects tend to disappear in a day or two. The flu vaccine is safe for most people, but those who are allergic to eggs should avoid it because of the potential for a serious allergic reaction. Because flu epidemics and pandemics represent a serious public health problem, scientists are constantly looking for new ways to prevent and treat the illness.
New therapies are now available and others are being developed.
