"With this arrival, it means that there are already 3 million doses of Sinovac vaccine in Indonesia," Indonesian Foreign Minister Retno Marsudi told a virtual press conference.

JAKARTA, Jan. 1 (Xinhua) -- A total of 1.8 million doses of COVID-19 vaccine made by the Chinese biopharmaceutical company Sinovac Biotech arrived in Indonesia on Thursday, according to Indonesian government officials.

Foreign Minister Retno Marsudi said this is the second batch of the Sinovac vaccine delivery for Indonesia, and the first batch of 1.2 million doses arrived on Dec. 6.

"With this arrival, it means that there are already 3 million doses of Sinovac vaccine in Indonesia," Marsudi told a virtual press conference.

Health Minister Budi Gunadi Sadikin said vaccination is one of Indonesia's main strategies to fight the COVID-19 pandemic, adding, "It would take more than 12 months to complete the vaccination program, so we always keep up to health protocols."
