It is the first COVID-19 vaccine patent granted by China, state-owned newspaper People’s Daily reported on Sunday.

The paper cited documents published by China’s National Intellectual Property Administration saying that the patent was issued on Aug. 11.

Saudi Arabia said this month it plans to begin Phase III clinical trials for the CanSino vaccine. CanSino has said it is also in talks with Russia, Brazil, and Chile to launch Phase III trials in those countries, Reuters reported.

Cansino’s Hong Kong shares rose around 14% in Monday’s morning session. Its Shanghai shares rose by 6.6% as of midday.

The vaccine candidate, produced by the Chinese firm of Sinovac Biotech, is among just a few in the world to enter Phase 3 clinical trials or large-scale testing on humans in Indonesia— the last step before regulatory approval.

The treatment, known as CoronaVac, is already being tested on 9,000 health workers in Brazil, the second-hardest-hit country in the coronavirus pandemic after the United States.

Indonesia, the world’s fourth most populous country, has been struggling to contain its mounting virus cases, with more than 127,000 confirmed infections and over 5,700 deaths.

But the true scale of the public health crisis is believed to be much bigger, given the Southeast Asian nation’s low testing rates.

The governor of Indonesia’s most populous province, West Java, was among 1,620 volunteers slated to take part in clinical testing, which was set to wrap up in February.

If the vaccine proves safe and effective, Indonesian officials said, there were plans to produce up to 250 million doses for the sprawling archipelago of nearly 270 million, although they gave few details of the tentative roll-out, AFP reported.

On Tuesday, Indonesia’s President Joko Widodo toured a factory in Bandung city, operated by state-owned pharmaceutical firm Bio Farma, where production would begin.

“Once again I want to highlight that the COVID-19 threat will not end until all people in Indonesia are vaccinated,” Widodo said ahead of the tour.
