The actual efficacy formula is
(ARU-ARV/ARU)*100
Where ARU is Attack rate unvaccinated and ARV is attack rate vaccinated.
Attack rate is calculated by= no of people with cases/total number of people exposed.
90% of healtbhcare workers out of 160,000 have been vaccinated. Thats 144000.
ARV: 0.002.
They don't state how many unvaccinated Indonesian HC workers got it so we cannot check for ARU for cases.
But we know 16 unvaccinated and 10 vaccinated died so we **can** calculate it for deaths.
ARU Deaths:0.001
ARV Deaths: 0.00006944444
Efficacy: (0.001-0.00006944444/0.001)*100= 93.05%
And this is for the highest exposure group.
