Indonesian President Joko Widodo said he would be the first person in the country to be vaccinated for Covid-19 as he unveiled a campaign promising free inoculations for everyone in world's fourth most populous nation.

Widodo's announcement comes as Indonesia battles misinformation over the virus in order to stave off a fresh wave of infections, with some 630,000 recorded by Wednesday and more than 19,000 deaths, according to AFP.

“The Covid-19 vaccine for all citizens will be free,” Widodo said in a video on his Twitter account.
