Brazil reveals 50.4% of China's coronavirus 'coronavirus' vaccine
Brazilian researchers revealed. The final results of China's coronavirus vaccine test indicate that This vaccine is effective against COVID-19 only at 50.4%.
Bloomberg News reports that researchers from the Brazilian Biomedical Institute Butanton said the test for the novel coronavirus vaccine, 'CoronaVac', developed by Xenovac Bi China's OTEC in the final point that The vaccine has an overall antiviral efficacy of only 50.38%, which only slightly exceeds the minimum threshold for approval. And much lower than the 78% estimate published last week.
At a press conference in the state of Sao Paulo on Tuesday, Jan. 12, 2021, scientists said They categorized six types of infection: asymptomatic, very mild, mild, 2 moderate and severe, the first two did not require medical support.
With 78% efficiency announced last week Calculated from the subjects with mild, moderate and severe symptoms and when a few infected were included. The effectiveness of the vaccine was therefore only 50.38%, while Butanton director Ricardo Palacio confirmed the vaccine had reduced the severity of the disease.
Palacio said the fact that the tests were carried out by healthcare workers. With high exposure to the virus And the matter that the vaccination two doses apart in a short time It is described as Why does the efficiency rate come out so low? And the inclusion of very mild patients Affect the final number as well
“We add all the possible difficulties. When you shorten the time between each vaccination. The immune response is also reduced, ”Palacio said.
However, the figures are disappointing for the Brazilian government. Because the Coronavac vaccine is one of the two vaccines that Brazil orders and prepares to administer them to the public. To tackle their second wave of COVID-19 outbreaks, the efficacy numbers were lower than their vaccines. Pfizer / Bio-Tech with Modena that is between 90-95% too.
