The new crown pneumonia epidemic continues, and the details of the vaccines ordered earlier were announced, including the research and development of Sinovac, but according to clinical data from a research institute in Brazil, the overall effective rate is only 50.38%.
Respiratory specialist Liang Zichao said on a TV program in Hong Kong and Taiwan this morning (14) that the relevant figures contained minor symptoms and did not require medical treatment, so they were dragged down.
He said that if only mild symptoms appear, it has actually helped to reduce the medical burden. In this regard, the three vaccines are actually not much different.

Liang Zichao said on the Hong Kong and Taiwan program "Millenniums" this morning that the so-called 50.38% effective rate actually reduces the risk of infection by 50.38%, including those with very mild symptoms and no medical treatment.
As for previous studies that indicated an effective rate of 78%, they only included data on requiring medical attention, moderate, and severe conditions.
He believes that the 50.38% effective rate is "dragged down" by very mild symptoms.
From a protection point of view, Liang Zichao pointed out that since there is no need to seek medical treatment for very mild symptoms, as long as the symptoms of moderate to high severity are reduced after vaccination, the medical burden can be reduced. In this regard, the three vaccines are actually not much different.
He continued that since the number of vaccines was initially insufficient for all citizens, we should now proceed from the perspective of personal protection, not herd immunity, and take the lead in vaccinating high-risk groups.
Liang Zichao believes that as long as the vaccine has enough data to provide a certain degree of protection safely and effectively, it should be used. At the moment, there is no need to worry too much about mild symptoms such as colds.
