In order to recognize if you have an Influenza Vaccines allergy, you'll have to understand the common symptoms typically associated with an allergic reaction to such vaccines. Take note if these symptoms occur shortly after you've had your flu shot.

Identify Potential Allergy Symptoms

• Difficulty in Breathing: If you experience shortness of breath, wheezing or have difficulty breathing after having the vaccine, it could indicate an allergy.
• Skin Reactions: Any redness, itchiness, hives or swelling at or around the injection site might suggest an allergy. More serious allergies could result in rashes elsewhere on your body as well.
• Dizziness or Lightheadedness: Feeling dizzy, weak or lightheaded could be another sign of an allergic reaction to the influenza vaccine.
• Rapid Heart Rate: An abnormally rapid heart rate, also known as tachycardia, after having the shot can be due to an allergy.

Note the Timing of the Reaction

Allergic reactions to vaccines like the flu shot typically occur within minutes to hours of receiving the shot. If you experience any of the above symptoms during this time frame, it could indicate an allergy to the vaccine.

Seek Medical Attention

It's important to consult a healthcare provider immediately if you experience any symptoms of an allergy after receiving the flu shot. They will be able to assess, confirm, and treat any potential allergy. It's always better to be safe, especially if the symptoms are severe.
