Pandemic (H1N1) 2009 influenza vaccine roll-out in NSW.

The roll-out of the pandemic (H1N1) 2009 influenza vaccine in NSW was significantly different to that envisaged for a pandemic vaccination program. Pre-pandemic planning had focused on the urgent roll-out of a vaccine through mass vaccination clinics in a time of high demand due to a virulent influenza virus. Instead the situation was less urgent, with the vaccine available only after the peak of incidence of infections in NSW. Consequently mass vaccination clinics were considered to be a less appropriate method of delivering the vaccine than a primary care focused delivery model. This paper describes the program, some of the controversies considered during its roll-out and factors to be considered in planning for future pandemics.
