Current issues with influenza vaccination in egg allergy

Abstract

Influenza infection, with its accompanying morbidity and mortality, represents a major public health concern yearly to the elderly and high-risk groups, including asthmatic patients. Active prevention with vaccination consistently falls short of reaching optimal immunization rates in all risk groups. Asthmatic patients and others with concomitant egg allergy might be denied active immunization because of the risk of inducing adverse reactions with a vaccine derived from egg embryo tissue. Evidence supports the relatively safe administration of influenza vaccine to individuals with egg allergy in whom vaccination is indicated when specific protocols are followed under the supervision of experienced physicians. A practical protocol that includes incremental dosing of influenza vaccine is presented to guide clinicians in influenza vaccination in this high-risk group.
