Jakarta. Coronavac, a vaccine made by Chinese pharmaceutical company Sinovac has been 98 percent effective in reducing the number of deaths due to Covid-19 among health workers in Jakarta, according to a study released by the Health Ministry on Wednesday.
………………
The study evaluated Covid-19 data between Jan 13 — when the vaccination first started in Indonesia — and March 18, tracking 128,290 health workers who had not suffered from the disease before the study period.
The study found only one Covid-19 related death among 91,777 health workers in 28 to 63 days after receiving two doses of Sinovac's vaccine. That was equal to a case fatality rate (CFR) of 0.0001 percent.
In comparison, there were three deaths among 8,485 health workers who received only one dose of the vaccine, resulting in the group's CFR of 0.03 percent. Among 28,055 health workers who had yet to be vaccinated, the study found 17 deaths, resulting in a 0.66 percent death rate.
In other words, the death rate dropped from 66 in 10,000 people to just one after two doses of vaccination, a decline of 98 percent — a number epidemiologists refer to as the vaccine effectiveness.

| Groups | Deaths | Total | % |

| Vaccinated with the first dose | 3 | 8,458 | 0.03 |
| Vaccinated with the second dose | 1 | 91,777 | 0.001 |

Also, the study found that complete Coronavac vaccination would be able to reduce hospitalization by 96 percent.

Indonesia has administered 22.5 million vaccines to 13.7 million people in priority groups, including the health workers, workers in private and public service industries, and the elderly since the vaccination began on Jan 13, the ministry data showed on Thursday.
Still, according to the government target of vaccinating 40 million people by the end of this month, the country should have administered at least 70 million doses of vaccine by Thursday.
