Can a patent waiver speed up the global COVID vaccination drive?

The world is far from having the number of COVID-19 vaccines needed to vaccinate every single person. Now, over 100 nations are pressing for a temporary patent waiver at the World Trade Organization to help speed up production.

Some have suggested pharmaceutical companies are prioritizing profits over lives. Supporters of the waiver demand that know-how and technology be shared more widely – because the pandemic, they say, is an extraordinary, emergency situation.

But a string of wealthy countries are opposing the waiver.

And some say even if one was put in place, it would not increase vaccine production.
