Check the dates again. The quadrivalent (4 strain) vaccine was licensed before the bivalent (2-strain Cervarix) vaccine, and Cervarix is inferior in other respects. Yet medical systems paid $50-2000 a dose for hundreds of millions of doses, knowing that it was obsolete.
- thedailymail 9y agoSorry, you're absolutely right on the dates! But how would planned obsolescence work if the inferior product is made by a competitor? It sounds more like a me-too drug scenario. Was Cervarix competing with Gardasil on price, with a tradeoff of less protection for lower cost?
