Indonesia has passed more than one million Covid-19 cases, as the archipelago launches one of the world's biggest vaccine drives to clamp down on a soaring infection rate.

The Southeast Asian nation of nearly 270 million has recorded 1,012,350 virus cases and almost 29,000 deaths, according to official data. But low testing rates mean the crisis is believed to be much bigger than those figures suggest.

Some hospitals are on the brink of collapse as they are overwhelmed with patients in one of Asia's worst-hit nations, public health experts warn.

According to an AFP report, the virus has killed more than 600 doctors, nurses and other medical workers, many outfitted with limited protection equipment, according to independent researchers.
