WHO OKs emergency use of China's Sinopharm vaccine


The World Health Organization gave emergency use authorization 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, reports Associated Press.

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 U.N. children's agency UNICEF and 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 said.

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 authorization from the U.N. health agency.

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. A summary posted online by WHO suggests the vaccine is about 78% effective, with the caveat that all but a few hundred of the study volunteers were younger than 60.

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

"This means the world has yet another safe and effective tool in the fight against this pandemic,” the alliance said.

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.

Many officials in countries without such regulatory structures rely on WHO’s emergency use listings to authorize vaccine rollouts for their populations.

Hundreds of millions of Chinese vaccines have already been delivered to dozens of countries around the world through bilateral deals as many scrambled to secure supplies after rich countries had reserved the vast majority of supplies from Western pharmaceutical makers.

While China has five shots in use, the majority of its exports abroad come from two companies: Sinopharm and Sinovac. A decision on Sinovac is expected next week, WHO said.

The Chinese vaccines are “inactivated” vaccines, made with killed coronavirus. Most other COVID-19 vaccines being used around the world, particularly in the West, are made with newer technologies that instead target the "spike" protein that coats the surface of the coronavirus.





Sinopharm said last month that over 100 million doses of its two vaccines have been used across the world.
