Covid: US backs waiver on vaccine patents to boost supply
The US has thrown its support behind a move at the World Trade Organization (WTO) to temporarily lift patent protection for coronavirus vaccines.
India and South Africa proposed the plan, which they said would increase vaccine production around the world.

But drugs manufacturers argue it may not have the desired effect.
US Trade Representative Katherine Tai said that "extraordinary times call for extraordinary measures".
And she warned that it would take time to reach an agreement on the matter.
One hundred members of the World Trade Organisation (WHO) are said to be in favour, and a panel on intellectual property is expected to discuss the issue next month.
Intellectual property means creations, such as inventions, are protected by patents, copyrights and trademarks - allowing the originator to be financially rewarded.
India and South Africa were the leading voices in a group of about 60 countries which for the last six months has been trying to get the patents on vaccines set aside.
However, they met with strong opposition from the previous US administration of Donald Trump, the UK and the EU.
But Mr Trump's successor as US President, Joe Biden, has taken a different tack. He backed a waiver on intellectual property associated with Covid vaccines during the 2020 presidential campaign and repeated his support on Wednesday.
The head of the WHO called the move a "monumental moment" in the fight against Covid-19.
What would the waiver mean?
If approved, supporters say, the waiver would allow production of vaccines to be ramped up and provide more affordable doses for less wealthy countries.
Many developing countries have argued that rules requiring countries to protect patents and other forms of intellectual property are an obstacle to increasing the production of vaccines and other products needed to tackle the pandemic.
The US had previously helped block WTO negotiations about the waiver proposal led by India and South Africa aimed at helping developing countries to produce vaccines using the intellectual property of pharmaceutical companies.
Ms Tai said the US would now embark on negotiations at the WTO to try to secure the waiver. This could take time as WTO decisions require a consensus of all 164 members.
What has the reaction been?
Tedros Adhanom Ghebreyesus, head of the WHO, called the US decision "historic" and marked "a monumental moment in the fight against Covid-19".
But pharmaceutical companies have voiced their opposition, insisting that patents are not the primary obstacle, and cautioned that the move could stifle innovation.
The International Federation of Pharmaceutical Manufacturers and Associations called the move "disappointing".
"A waiver is the simple but the wrong answer to what is a complex problem," the Geneva-based lobby group said.
Dr Amesh Adalja, senior scholar at the Johns Hopkins Center for Health Security, told the Reuters news agency that the waiver "amounts to the expropriation of the property of the pharmaceutical companies whose innovation and financial investments made the development of Covid-19 vaccines possible in the first place".
Some experts say pharmaceutical companies would also need to share know-how, such as production techniques, with poorer countries to have any real beneficial effect.
Licensing agreements are another way of boosting production.
One of the largest Covid vaccine producers is the Serum Institute of India which manufactures the Oxford-AstraZeneca jab under a licensing agreement with the Anglo-Swedish company.
