"By August, Canada will have enough to fully vaccinate its entire population", reads a statement signed by 32 agencies and organizations, including the Canadian arms of One, UNICEF, World Vision, the Mennonite Central Committee, Canadian Council of Imams and the Anglican Council of Indigenous People.
"And the United States is committed to bringing the same urgency to global vaccination efforts that we have demonstrated at home".
COVAX, or COVID-19 Vaccines Global Access, is a World Health Organization-backed global vaccine program helping with the distribution, but Sullivan added at the briefing that the us will have a final say on where the doses go and its effort is focused on countries dealing with "urgent" needs.
The other 60 million doses are from AstraZeneca, yet to be approved by the US Food and Drug Administration. "We are sharing these vaccines to save lives and to lead the world in bringing an end to the pandemic", Mr Biden said.
For Southeast Asian countries, it is a "symbolically important" first step, but the dose shipments are a "drop in the bucket" compared to what is needed in the region, said Alex Feldman, head of the U.S. -ASEAN Business Council, a lobbying group.
SII, the world's largest vaccine maker and a top supplier of COVID-19 shots to low- and middle-income countries, had criticized the use of the DPA, and Reuters reported in May that a shortage of US -made raw materials would hit production of Novavax's vaccine.
The DPA ratings give US producers priority access to supplies and equipment needed to manufacture the vaccines that are in short supply around the world.
The Associated Press reports that scores of nations have requested doses from the United States - but so far only Canada and Mexico have received any directly from the USA - with both nations sharing a total of 4.5 million doses. "We also discussed ongoing efforts to further strengthen India-US vaccine cooperation, and the potential of our partnership to contribute to post-Covid global health and economic recovery". Some vaccines have expiry dates as soon as the end of June, it has been reported by Politico.
Secretary of State Antony Blinken earlier this week promised the US would work in conjunction with COVAX and "distribute vaccines without political requirements of those receiving them".
The president has also promised to share 20 million doses from existing production of Pfizer, Moderna and Johnson & Johnson vaccine stocks.
However, Bruce Aylward said on Friday that only a small portion of those doses will be available in the short-term in June, July and August when they can make a difference in slowing the pace of infections in the global pandemic.
What should Canada do with the AstraZeneca-Oxford vaccine doses in storage? The U.S. will share up to one-quarter of its donated doses directly with countries in need, those experiencing surges, immediate neighbors, and other countries that have requested immediate U.S. assistance. That's why today, I'm announcing that over the next six weeks we will send 80 million vaccine doses overseas.
The White House also announced Thursday that it is lifting restrictions on sharing vaccines produced by AstraZeneca, as well as Sanofi and Novavax, which are also not authorized in the USA, allowing the companies to determine themselves where to share their doses.
Recipients of the direct donations will include South Korea, where Washington pledged to provide vaccinations for 500,000-plus service members as part of a May agreement between U.S. President Joe Biden and South Korean President Moon Jae-in.
The US' announcement comes at a time when the Narendra Modi government is trying to allay concerns about shortages of vaccine and ward off allegations of mishandling of the inoculation drive. That shot has not been authorized for US use and is still under review by the Food and Drug Administration.
