Does the detection of DNA from PCV1 in Rotarix raise special concerns for influenza vaccines?
No. The manufacturing process for Rotarix is very different from the manufacturing process for influenza vaccines. Unlike Rotarix, a cell-based vaccine, the influenza vaccines currently on the market are egg-based vaccines. The cell-based influenza vaccine currently in development uses materials that are different from the one used to develop Rotarix.
