China’s Sinovac Covid-19 vaccine has been found to be significantly less effective than previous data has suggested. Brazil’s biomedical centre Butantan Institute, which is running final-stage clinical trials for the vaccine called CoronaVac, released new data on January 12, 2021. It said the vaccine has an efficacy rate of 50.4 per cent, a figure way lower than the 78 per cent suggested by data released one week earlier by the São Paulo-based institute. The World Health Organization requires all vaccines to have at least 50 per cent efficacy.

I've been told by family doctor who's my uncle. He works in a hospital and says "we are killing people, we are putting them on ventilators knowing the lungs could explode, we put people who don't have covid in the covid section. After hearing this coming from family. So who is giving out this order?
