GENEVA, Switzerland (AFP) — Years of negotiations culminated in the wee small hours of Wednesday with countries agreeing the text of a landmark accord on how to tackle future pandemics, aimed at avoiding a repeat of the mistakes made during the Covid-19 crisis.

After more than three years of talks and a final marathon session, weary delegates at the World Health Organization’s (WHO) headquarters could finally pop the champagne corks at around 2 a.m. Wednesday.

“The nations of the world made history in Geneva today,” WHO chief Tedros Adhanom Ghebreyesus said in a statement.

Negotiators had stumbled over the agreement’s Article 11, which deals with transferring technology for pandemic health products, sources told Agence France-Presse.

During the Covid-19 pandemic, poorer countries accused rich nations of hoarding vaccines and tests.

Countries that have large pharmaceutical industries have strenuously opposed the idea of mandatory tech transfers, insisting they be voluntary.

It appeared the tech transfer obstacle could be overcome by adding that any transfer needed to be “mutually agreed.”

In the end, the 32-page agreement was entirely highlighted in green, indicating it had been fully approved by WHO member states.

“It’s adopted,” Anne-Claire Amprou, co-chair of the negotiations, announced to thundering applause.

The finalized text will now be presented for sign-off at the WHO’s annual assembly next month.

As intense talks in corridors and closed rooms continued at the WHO headquarters, Tedros joined the negotiations late Tuesday and told reporters he thought the current draft was “good,” “balanced” and that a deal would bring “more equity.”

While taking measures to coordinate pandemic prevention, preparedness and response could be costly, Tedros insisted that “the cost of inaction is much bigger.”

“Virus is the worst enemy. (It) could be worse than a war,” he said.

The United States, which has thrown the global health system into crisis by slashing foreign aid spending, was not present. US President Donald Trump ordered a withdrawal from the United Nations’ health agency and from the pandemic agreement talks after taking office in January.

However, the US absence, and Trump’s threat to slap steep tariffs on pharmaceutical products, still hung over the talks, making manufacturers and governments more jittery.
