Influenza virus changes constantly, making vaccine production challenging. Changing the growth substrate from eggs to cell culture raises issues at all stages of the process, from surveillance to the assay of vaccines. The pandemic threat-first H5N1, then H1N1-encouraged a review of methods and brought issues into sharp relief.
