Can Immunizations and Vaccines Cause Allergic Reactions?
While rare, Immunizations and Vaccines can cause allergic reactions in some children. These reactions typically occur shortly after the vaccine is administered and can range from mild to severe. Mild allergic reactions may include symptoms such as hives, itching, or swelling at the injection site. Severe allergic reactions, known as anaphylaxis, are extremely rare but can be life-threatening if not treated immediately. Symptoms of anaphylaxis may include difficulty breathing, swelling of the face and throat, rapid heartbeat, dizziness, or loss of consciousness.
It's important to inform your child's healthcare provider about any known allergies, especially to components commonly found in vaccines, such as eggs, gelatin, or yeast. If your child has had a severe allergic reaction to a previous vaccine, your healthcare provider may take special precautions, such as administering the vaccine in a controlled medical setting where immediate treatment can be provided if necessary.
