Well, I thought I'd heard something about the vaccine being made in/with eggs. Some people can't tolerate them.[/quote]
TIV
TIV should not be administered to persons known to have anaphylactic hypersensitivity to eggs or to other components of the influenza vaccine. Prophylactic use of antiviral agents is an option for preventing influenza among such persons. Information regarding vaccine components is located in package inserts from each manufacturer. Persons with moderate to severe acute febrile illness usually should not be vaccinated until their symptoms have abated. However, minor illnesses with or without fever do not contraindicate use of influenza vaccine. GBS within 6 weeks following a previous dose of TIV is considered to be a precaution for use of TIV.
LAIV
LAIV is not currently licensed for use in the following groups, and these persons should not be vaccinated with LAIV:
persons with a history of hypersensitivity, including anaphylaxis, to any of the components of LAIV or to eggs.
persons aged <5 years or those aged >50 years;
persons with any of the underlying medical conditions that serve as an indication for routine influenza vaccination, including asthma, reactive airways disease, or other chronic disorders of the pulmonary or cardiovascular systems;
other underlying medical conditions, including such metabolic diseases as diabetes, renal dysfunction, and hemoglobinopathies; or known or suspected immunodeficiency diseases or immunosuppressed states;
children or adolescents receiving aspirin or other salicylates (because of the association of Reye syndrome with
wild-type influenza virus infection);
persons with a history of GBS; or
pregnant women
