Manufacturing and supply of COVID-19 vaccines and drugs

US Gov’t To Expand Availability of Pfizer’s COVID-19 Drug
The US government has announced plans to expand the availability of Paxlovid (nirmatrelvir tablets and ritonavir tablets), Pfizer’s oral COVID-19 treatment, with a commitment to purchase 20 million treatment courses.

Since December 2021, the Administration has distributed COVID-19 oral antivirals, and in March (March 2022), as supply began to ramp up, President Biden announced the Test-to-Treat initiative to help make it easier for people at high risk of severe disease to quickly access oral antiviral treatments. The Test-to-Treat initiative creates additional locations where people can get a COVID-19 test, a visit with a medical provider, and, if needed, free oral antiviral pills—all in one visit.

In an April 26, 2022 statement, the Biden Administration announced new actions for the availability of these treatments, including: (1) nearly doubling the number of places oral antivirals are available; (2) launching federally supported Test-to-Treat sites; (3) providing more guidance and tools healthcare providers to understand and prescribe treatments; and (4) provide more communication on the availability of these treatments.

Oral antivirals for treating COVID-19 are available in about 20,000 locations across the US. The Biden Administration expects that oral antivirals will soon be available in more than 30,000 locations. The US Department of Health and Human Services is working with pharmacy partners to increase availability to up to 40,000 sites over the coming weeks (as reported on April 26, 2022).

Additionally, building on the current 2,200 Test-to-Treat sites in pharmacies and other clinical settings, the US government will work with states and jurisdictions to establish additional Test-to-Treat locations with federal support.
