I think what you're referring to are two processes. There is a proposal that was put forward by a number of countries led by India and South Africa. It was presented to the TRIPS council quite a while ago—I believe it was in October 2020—and it has been an ongoing discussion.
The other process that you're referring to is one that is led by the director general of the WTO. It's the so-called quadrilateral process that includes the U.S., the European Union, South Africa and India. That process was launched in December and is ongoing.
