Russia has developed the first vaccine offering "sustainable immunity" against the coronavirus, President Vladimir Putin announced Tuesday. Putin also said his daughter inoculated with the new Russian coronavirus vaccine.

"This morning, for the first time in the world, a vaccine against the new coronavirus was registered" in Russia, he said during a televised video conference call with government ministers. "One of my daughters had this vaccine. I think in this sense she took part in the experiment," Putin said.

Russia has been pushing hard to quickly develop a coronavirus vaccine and said earlier this month it hoped to launch mass production within weeks and turn out "several million" doses per month by next year.

The World Health Organization last week urged Russia to follow established guidelines and go "through all the stages" necessary to develop a safe vaccine. 

The pandemic has seen an unprecedented mobilisation of funding and research to rush through a vaccine that can protect billions of people worldwide.

Indonesia starts human trials

Indonesia on Tuesday launched human trials of a Chinese-made coronavirus vaccine with some 1,600 volunteers slated to take part in the six-month study.

The vaccine candidate, produced by Sinovac Biotech, is among just a few in the world to enter Phase 3 clinical trials, or large-scale testing on humans -- 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.

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.
