GENEVA (AP) — The World Health Organization gave emergency use authorisation Friday to a COVID-19 vaccine manufactured by China’s Sinopharm, potentially paving the way for millions of the doses to reach needy countries through a U.N.-backed program rolling out coronavirus vaccines.

The decision by a WHO technical advisory group — a first for a Chinese vaccine — opens the possibility that Sinopharm’s offering could be included in the U.N.-backed COVAX program in coming weeks or months and distributed through UNICEF and the WHO’s Americas regional office.

Aside from efficacy numbers, the Chinese manufacturer has released very little public data about its two vaccines — one developed by its Beijing Institute of Biological Products and the other by the Wuhan Institute of Biological Products.

The Beijing shot is one the WHO advisory group considered for the emergency use listing.

“This afternoon, WHO gave emergency use listing to sign off on Beijing’s COVID-19 vaccine, making it the sixth vaccine to receive WHO validation for safety, efficacy and quality,” WHO Director-General Tedros Adhahom Ghebreysus told reporters.

The Sinopharm vaccine will join ones made by Pfizer-BioNTech, Johnson & Johnson, Moderna, AstraZeneca, and a version of the AstraZeneca vaccine made by the Serum Institute of India, in receiving the coveted authorisation from the U.N. health agency.

The announcement raised the prospect that the Chinese vaccine, which has already been exported by millions of doses in some countries, could join the U.N.’s arsenal against COVID-19 at a time when supplies of other Western-made or -developed vaccines have been lacking.

“The addition of (the Sinopharm) vaccine has the potential to rapidly accelerate COVID-19 vaccine access for countries seeking to protect health workers and populations at risk,” said Dr. Mariangela Simao, WHO assistant director general for access to health products.

Arnaud Didierlaurent, a professor at the University of Geneva’s medical school who chairs the advisory group, said it had requested additional studies from Sinopharm, and that there would be “continuous evaluation” of the vaccine.

“In fact, the work does not stop after the listing,” he said.

Medical regulators in the European Union, Britain and the United States have not examined the Sinopharm jab, which relies on relatively old vaccine technology.

The WHO, in what it called a first, said the vaccine would come a small sticker on the vaccine vials that changes color as it is exposed to heat, which will inform health workers about whether the vaccine can be safely used.

Previously, a separate group advising WHO on vaccines said it was “very confident” the Sinopharm vaccine protects people ages 18-59.

The group said it had a “low level of confidence” in the vaccine’s efficacy for people 60 and over.

Its members said they had “very low confidence” in the available data about serious side effects in that age group.

Sinopharm hasn’t published its late-stage test results in scientific journals, so the WHO requested a breakdown of its data, which come mostly from the United Arab Emirates.

″(We) came to the conclusion that there is enough evidence of safety and the capacity of the vaccine to prevent severe disease or symptomatic and hospitalised cases up to 79%,” said Dr. Alejandro Cravioto, who heads the WHO advisory group on immunizations.

“The information we have for people over 60 is still very scarce.”

“There is no reason to think that the vaccine would behave differently in this older age group,” he added.

Gavi, the Vaccine Alliance, which co-runs COVAX, welcomed the announcement.

COVAX aims to send vaccines for free to 92 lower-income countries and to help another 99 countries and territories procure them.

It was not immediately clear when the Chinese vaccine might be made available to the COVAX portfolio

The program, which has already distributed over 54 million doses of COVID-19 vaccines but faces limited supplies from Western countries and India, has been working hard to strike deals as part of its goal to procure 2 billion doses by the end of the year.
