To be clear: There's no evidence that there is anything wrong with Intercell's products.
However, other companies have tried needle- and pill-free medicine delivery systems in the form of patches in the past and been burned, including Johnson & Johnson (JNJ), Watson (WPI), Shire (SHPGY) and Noven (NOVN).
Watson's fentanyl pain control patch has been recalled at least six times. And Shire and Noven collaborate on the Daytrana ADHD patch, which has been recalled eight times.
GSK and Intercell said they would explore using patches for other vaccines in GSK's portfolio. GSK might want to make sure the product does what it says on the box before rolling it out through all available franchises.
