In a very recent study involving 86,936 Jakarta, Indonesia residents aged 60 and above between March and April this year, shows that CoronaVac is 85 per cent effective against symptomatic illness and 92 per cent against hospitalization among the elderly.

The China-made vaccine is 95 per cent effective in preventing deaths, a chart from the Indonesian health ministry showed.



The effectiveness against symptomatic illness is reduced to 35 per cent if only the first jab is given.

Vaccine effectiveness refers to the performance of a vaccine in a population under a real-world situation, while vaccine efficacy refers to the performance of a vaccine in a controlled clinical trial situation, according to the World Bank.



The study also revealed that chances of a vaccinated elderly dying of Covid-19 are up to 15 times less than someone who is not vaccinated.

A separate study by the health ministry on 25,374 medical workers in the capital between January and March this year showed that CoronaVac was 96 per cent effective against hospitalization, 94 per cent against infection and 100 per cent in preventing deaths.



While I have reservations on the figure or data that were presented by DOH today regarding the 73% increase from Wednesday’s 7,992 cases to today’s 11, 021 cases, I agree with them that we should get vaccinated of the WHO recommended and approved vaccines available in the country starting from the first arrival of the Sinovac vaccines from China and especially now during the two week lockdown. This is very important especially now that the Delta strain is causing this spike in cases in NCR and other regions of the country.
