This is a rather lop-sided view of the matter.

It implies that a TRIPS waiver is the only thing preventing a more equitable distribution of vaccine supplies. Also, the use of the past tense ("...blocked....") implies that the door to a TRIPS waiver is forevermore closed.

Neither implication is correct.

The WTO is still discussing a TRIPS waiver. See https://www.wto.org/english/news_e/news21_e/trip_11mar21_e.htm, which is a far more recent source than the Reuters article that you linked to.

Not that a waiver would make much difference: it's not the only obstacle a more equitable distribution of vaccines.

A much more nuanced and complete review of the TRIPS matter is available in The Conversation: https://theconversation.com/intellectual-property-and-covid-19-medicines-why-a-wto-waiver-may-not-be-enough-155920.

It should become evident from reading that article that a TRIPS waiver is necessary but nowhere near sufficient to distribute vaccines more equitably. And that many of critical hindrances that would remain are purely internal/national matters beyond the scope of the WTO, to the countries that are currently suffering the greatest shortage of vaccines.

Is it better to distribute vaccines equitably? Of course it is! Duh!

Is it possible to do so? Not as the world's nations are currently arranged.

This is not because "the West is Evil". This is because humanity is stupid and selfish and lazy. All peoples are, everywhere, regardless of background, income, and nationality.
