President Joko Widodo said he hoped Indonesia's Covid-19 vaccination rollout would hit one million shots a day by July, as authorities opened up inoculations to anyone aged over 18 in Jakarta to contain increased transmission in the capital.

Reuters reports that during a visit to Depok, south of Jakarta, the president said he wanted vaccinations to hit a targeted 700,000 doses a day this month and then rise again.

"So in July, we can achieve the vaccination target per day of 1m," said the president, who is widely known as Jokowi.
