Pfizer expects to make as much as $22bn from its new Covid pill this year, on top of $37bn it made in 2021 from the vaccine. Pfizer’s Paxlovid currently costs about $530 for a five-day course of the treatment. Merck’s molnupiravir, now approved for use in the U.K., costs about $700. Reportedly, the cost of production for molnupiravir stands at about $17.74. Experts across the board are predicting demand for antiviral drugs will rapidly outpace supply.
