Traditional influenza vaccine production uses fertilized hen eggs. This method is labor-intensive and requires large facilities with limited scalability. A switch to cellculture–based vaccine production methods and use of disposable products would provide flexibility to substantially reduce the time to vaccine clinical trials and approval, effectively decreasing the time-to-market. The aim of this work was to establish a process to propagate influenza virus in Vero cell culture using animal-component–free conditions for cell growth and disposable…
