The proposed temporary waiver was first suggested by India and South Africa at a World Trade Organization (WTO) meeting in October and is “gathering support from a large number of developing countries”, Reuters reports. The plan’s backers argue that making coronavirus jabs more widely available is a “vital step” in combating the global pandemic, says the news agency. The US had previously withheld its support, however, alongside the EU, UK, Japan, Switzerland, Brazil and Norway. But now supporters of the waiver are hoping that “US leadership on the issue could help sway other holdouts”, following the change of heart by Joe Biden’s administration, says Al Jazeera.
