The most important medical contraindication of inactivated vaccines used in our country is the condition in which the person is allergic to substances within the vaccine.
People who have developed an allergic reaction against a previous flu shot should not be vaccinated against influenza. People with a history of egg allergy can get influenza vaccine under medical supervision.
Additionally, influenza vaccination is not recommended for people who had developed a special neurological disorder called Guillain-Barré Syndrome after a previous flu shot.
