This week, domestic regulators approved a Covid-19 vaccine produced by China's Sinovac, announcing that its efficacy stood at a relatively low 65.3 percent, according to tests performed in Indonesia.

The Muslim-majority nation's top religious body also approved the vaccine as halal -- meaning permissible under Islam -- in a move that could help convince wary citizens.

Previous vaccination drives have met resistance among some segments of the country's huge population, the world's fourth largest.

"This vaccination is important to break the chain of coronavirus infections and to give health protection to all of us, and safety and security for all Indonesians," Jokowi told reporters, adding that it would "also help speed up the economic recovery".

It has reported nearly 850,000 Covid-19 cases and close to 25,000 deaths, but low testing rates mean the public health crisis is believed to be much bigger than the figures suggest.
