A health worker gives a dose of the Covid-19 Sinovac Biotech vaccine to people in their cars and motorbikes during the mass drive-thru vaccination program in Medan on April 8, 2021, North Sumatra, Indonesia. The mass vaccination, which is focused on the elderly, is targeted to receive the vaccine per day for 1000 people along with their companions. Until April 2021, Indonesia has reached 12.7 million vaccinations, where the country's government continues to struggle in earnest to use the Covid-19 Sinovac Biotech vaccine developed by China.

Interview with the Head of the Medan City Health Office, Doctor Edwin Effendi "We hope that every day we can achieve the 1000 people we do in the first month and continue according to our needs with the availability of our vaccines".
