The flu shot delivers influenza vaccine in an injection, providing protection against seasonal influenza. According to the U.S. Centers for Disease Control and Prevention, or CDC, babies age 6 months and older are recommended to receive the influenza vaccine every year prior to influenza season, which usually begins in early fall. There are certain side effects associated with the flu shot in babies that parents and caregivers should be aware of.
Injection Site Complications
According to the CDC, patients may experience soreness, redness or swelling where the shot was given. Parents should use additional caution while bathing, clothing and handling a baby following vaccination so as not to place additional pressure on the injection site. Applying a cool compress to the affected area may help lessen swelling and discomfort. These side effects should diminish within several days following vaccination with the flu shot.
Fever and Muscle Aches
Symptoms such as fever, chills and muscle aches occur in less than 1 percent of people receiving the flu shot, usually those receiving it for the first time, reports Baby Center. Use of an over-the-counter pain and fever reliever such as infant acetaminophen can be taken prior to or immediately following vaccination to help relieve muscle aches and fever. Babies may appear more irritable during this time due to fever and body aches. If fever is not relieved by medication and is accompanied by severe irritability, a health care provider should be notified. According to the CDC, if these problems occur, they begin soon after the shot and usually last 1 to 2 days.
Serious Side Effects
In rare cases, a serious side effect may occur in babies receiving the influenza vaccine. Babies or children allergic to chicken eggs are at higher risk for developing an allergic reaction and should not receive the flu shot. Some babies may develop a seizure following vaccination with the influenza vaccine. According to the CDC, additional signs and symptoms of a severe reaction can include high fever, behavior changes, difficulty breathing, hoarseness or wheezing, hives, paleness, weakness, a fast heart beat or dizziness. Parents or caregivers who are concerned about the possible side effects associated with this vaccination should consult their physician for additional information.
