Merck plans to double manufacturing capacity for its antiviral pill to treat Covid-19 next year as governments scramble to procure a treatment that a late-stage trial showed cuts hospitalisation and death rates in half.
The mounting demand for Merck’s drug, the first oral treatment shown to prevent severe disease in vulnerable people with coronavirus, is a sign that it could trigger the same kind of worldwide rush faced by makers of early Covid-19 vaccines.
Merck, which this week asked US regulators to authorise use of the drug called molnupiravir, told the Financial Times it had secured deals with Singapore, New Zealand, Australia and South Korea to supply doses in the past week and is in talks with several other governments.
