The flu vaccine is a vaccination intended to prevent the seasonal flu. The flu is a highly contagious viral illness that is spread through person-to-person contact. On February 24, 2010 vaccine experts voted that everyone 6 months and older should get a flu vaccine each year starting with the 2010-2011 influenza season, explains the Centers for Disease Control and Prevention. There are some complications associated with the flu vaccine.
Injection Site Complications
According to the U.S. Centers for Disease Control and Prevention, or CDC, at least half of all people who receive this vaccination will experience mild side effects, such as pain or redness where the injection was given. Mild swelling, bruising, or a small hard lump at or around the site of injection can also occur. These side effects should be temporary and diminish a few days following vaccination. The application of a cool compress may help to relieve swelling and discomfort of the affected area. Parents or caregivers of vaccinated children should use caution while holding and changing the child, as not to place additional pressure on the site of injection. If pain and soreness become bothersome a physician should be consulted. He may recommend the use of an over-the-counter pain reliever such as acetaminophen for the relief of pain and discomfort.
Flu-Like Symptoms
Patients may develop flu-like symptoms following injection with the influenza vaccine. According to BabyCenter, symptoms such as fever, chills, and muscle aches occur in less than 1 percent of people receiving the flu shot with symptoms lasting up to two days. Severe flu-like symptoms or a high fever that is accompanied by seizure or changes in behavior should be reported to a physician immediately.
Severe Complications
In rare cases, a serious side effect may occur following vaccination with the flu vaccine. Patients who are allergic to chicken eggs or those who have experienced a previous allergic reaction to a flu vaccine should not take this vaccination. According to the CDC, additional signs and symptoms of a severe reaction can include high fever, behavior changes, difficult breathing, hoarseness or wheezing, hives, paleness, weakness, a fast heart beat or dizziness.
