Flu vaccines contain detectable amounts of egg protein, which may pose a risk to egg-allergic individuals. The 2009 H1N1 influenza pandemic required mass vaccination in many countries, and the safety of flu immunization in egg allergy became of increasing public health importance. This article reviews recent literature and provides an updated guideline for immunization during the 2011–2012 flu season. Recent experience suggests that some vaccines with very low ovalbumin concentrations may be safe for use in primary care in carefully assessed low-risk individuals.
