Low risk of recurrence of oculorespiratory syndrome following influenza revaccination.

Abstract

We found a low risk of recurrence of ORS for individuals previously affected in 2000 when they were revaccinated in 2001, including those whose ORS in 2000 had prevented daily activities but was not clinically severe. Health care providers should be confident in the safety of recommending revaccination of these individuals. As with all vaccines, however, a detailed risk-benefit assessment should be undertaken before revaccination of people whose previous adverse event experience may have included collapse, respiratory difficulty (including throat tightness) and/or chest discomfort requiring emergency intervention.
