The World Health Organization (WHO) said it would announce a "landmark collaboration" later today to speed up development of safe, effective drugs, tests and vaccines to prevent, diagnose and treat COVID-19.

The Geneva-based agency said the initiative with partners aims to make technologies against the disease caused by the novel coronavirus "accessible to everyone who needs them, worldwide," but gave no details.

The GAVI vaccine alliance, Gates Foundation and Global Fund are among traditional large donors to the UN agency, in addition to its 194 member states.

WHO director-general Tedros Adhanom Ghebreyesus said on April 6 that he planned to announce an initiative to accelerate the research, development and production of vaccines and also design mechanisms for equitable distribution.

"WHO is committed to ensuring that as medicines and vaccines are developed they're shared equitably with all countries and people," Tedros said at the time.

"While we're looking for vaccines, unless we break the barriers to equitable distribution of the products, whether it's vaccines or therapeutics, we will have a problem, so we need to address the problem ahead of time," he said.

"There should not be a divide between the haves and the have-nots." Tedros also praised Costa Rica's President Carlos Alvarado for a proposal to create a voluntary pool of rights to tests, drugs and vaccines with free access or licensing on "reasonable and affordable terms for all countries."

"Tedros supports equitable access," a European diplomat said on Thursday. "The big challenge, apparently, will not be the development of a vaccine but then how to ensure broad roll-out for everybody."

The initiative is expected to include a stockpile for use in poor countries, such as the WHO currently has for influenza vaccines should a flu virus evolve into a pandemic.

During the H1N1 swine flu pandemic in 2009, there were bottlenecks in regulatory processes and vaccine yields were lower than expected, a subsequent WHO review found. There was criticism that distribution of vaccines was not equitable as wealthier countries were able to purchase more.
