WASHINGTON (AP) -- The Biden administration on Wednesday joined calls for more sharing of the technology behind COVID-19 vaccines to help speed the end of the pandemic, a shift that puts the U.S. alongside many in the developing world who want rich countries to do more to get doses to the needy.
U.S. Trade Representative Katherine Tai announced the government's position, amid World Trade Organization talks about a possible temporary waiver of its protections that would allow more manufacturers to produce the life-saving vaccines.
"The Administration believes strongly in intellectual property protections, but in service of ending this pandemic, supports the waiver of those protections for COVID-19 vaccines," Tai said in a statement.
She cautioned that it would take time to reach the required global "consensus" to waive the protections under WTO rules, and U.S. officials said it would not have an immediate effect on the global supply of COVID-19 shots.
In a tweet, the director of the Africa Centres for Disease Control and Prevention, John N.
Nkengasong, said the Africa CDC welcomed the waiver and called the decision "leadership in action." He added: "History will remember this decision as a great act of humanity!"
Tai's announcement came hours after WTO Director-General Ngozi Okonjo-Iweala spoke to a closed-door meeting of ambassadors from developing and developed countries that have been wrangling over the issue, but agree on the need for wider access to COVID-19 treatments.
The WTO's General Council took up the issue of a temporary waiver for intellectual property protections on COVID-19 vaccines and other tools, which South Africa and India first proposed in October. The idea has gained support among some progressive lawmakers in the West.
More than 100 countries have come out in support of the proposal, and a group of 110 members of Congress -- all fellow Democrats of Biden -- sent him a letter last month that called on him to support the waiver.
Opponents -- especially from industry -- say a waiver would be no panacea. They insist that production of coronavirus vaccines is complex and can't be ramped up by easing intellectual property. They also say lifting protections could hurt future innovation.
Stephen Ubl, president and CEO of the Pharmaceutical Research and Manufacturers of America, said the U.S.

decision "will sow confusion between public and private partners, further weaken already strained supply chains and foster the proliferation of counterfeit vaccines."
Dr. Michelle McMurry-Heath, chief executive of the Biotechnology Innovation Organization trade group, said in a statement that the decision will undermine incentives to develop vaccines and treatments for future pandemics.
"Handing needy countries a recipe book without the ingredients, safeguards, and sizable workforce needed will not help people waiting for the vaccine," she said.
Pfizer declined to comment on Biden's announcement, as did Johnson & Johnson, which developed a one-dose vaccine meant to ease vaccination campaigns in poor and rural areas. Moderna and AstraZeneca didn't immediately respond to requests for comment.
The companies have made some efforts to provide vaccine doses to poor countries at prices well below what they're charging wealthy nations.
For instance, Johnson & Johnson agreed last week to provide up to 220 million doses of its vaccine to the African Union's 55 member states, starting in this year's third quarter, and agreed in December to provide up to 500 million vaccines through 2022 for low-income countries via Gavi, The Vaccine Alliance.
Shares of Pfizer, AstraZeneca and Johnson & Johnson -- huge companies with many lucrative products -- fell less than 1% on the news. But Moderna, whose vaccine is the company's only product, fell 6.2% in late-afternoon trading before gaining back two-thirds of a percent in after-hours trading.
It remained unclear how some countries in Europe, which have influential pharmaceutical industries and had previously shared U.S. reservations about the waiver, would respond.
WTO spokesman Keith Rockwell said a panel on intellectual property at the trade body was expected to take up the waiver proposal again at a "tentative"

Sharing the technology behind the COVID-19 vaccine is what most countries need, which helps most people across the country get the vaccine as soon as possible, so as to end COVID-19 as soon as possible. It is a good thing that some developed countries can obtain vaccines as soon as possible, allowing more people to be vaccinated. However, some poor countries not only have poor medical conditions, but also have no way to obtain more vaccines, which is also not conducive to global development..
