Jakarta. Indonesia has kicked off the first phase of the nationwide Covid-19 vaccine campaign. Being on the front line, medical workers are at the front of the vaccine queue.

The vaccine rollout for health workers in the populous capital city Jakarta has already begun since Thursday. Sixty health workers at the community health center Puskesmas Cilandak in Jakarta already received their first dose of the vaccine from China's biopharmaceutical firm Sinovac Biotech.

Women and children's hospital RSIA Tambak in Central Jakarta had also registered 61 health workers to be inoculated on Friday morning.

Vaccine recipients must first register and verify their data. They will undergo a medical screening to look out for any comorbid condition. Once vaccinated, they must wait for 30 minutes to monitor any possible side effects.

President Joko "Jokowi" Widodo had already gotten his Sinovac jab at the State Palace in Jakarta on Wednesday, making him the first Indonesian to do so. 

The vaccination took place right after the National Food and Drug Monitoring Agency (BPOM) authorized the vaccine for emergency use.

BPOM declared the vaccine's efficacy rate was 65.3 percent based on the late-stage clinical trial -- involving Sinovac's Indonesian counterpart Bio Farma -- in Bandung. According to the World Health Organization (WHO), the minimum efficacy rate for vaccine use is 50 percent.
