"This virus looks more and more flu-like. It changes back and forth. After the change, will your vaccine still work? The vaccine at least provides you with the most basic immunity", Gao Gao, academician of the Chinese Academy of Sciences and director of the Chinese Center for Disease Control and Prevention Fu said at the 2021 Pujiang Innovation Forum Global Health and Development Forum on the 4th.
Gao Fu further explained that the reason why the flu vaccine is needed is to reduce the burden of disease. The vaccine provides us with basic basic immunity.
Gao Fu said that the relationship between viruses and humans is like a game of cats and mice. They are gradually adapting. Cats can't eat mice, and mice can't treat cats. Many viruses have such a relationship with humans.

Do we necessarily need vaccines to overcome all infectious diseases? Zhang Wenhong, director of the Department of Infectious Diseases at Huashan Hospital affiliated to Fudan University, said in a video speech that in fact, this is not always the case. In human history, countless infectious diseases coexist with humans, and countless viruses, bacteria, and fungi coexist with humans. In most cases, humans have co-evolved with viruses over many years. Eventually, diseases will take root in human society, and at the same time, humans will gain the ability to deal with it.
But Zhang Wenhong pointed out that for some particularly serious infectious diseases, such as smallpox, cholera, and plague, if we do not take special vaccine measures, public health measures, or treatment measures, we will encounter big problems.
Regarding the new crown virus, Zhang Wenhong said that if vaccination is not adopted, very strict public health measures must be adopted. “A saying that everyone often says in the history of infectious diseases is: as long as there is one such case in the world, we will It cannot be said that we have eliminated this infectious disease, which means that once the country is opened, we will still face great risks."
Does herd immunity work? Zhang Wenhong analyzed that if there was no very strong modern public health strategy in the past, and there was no very strict general vaccination situation, it would eventually take up to several decades for us to truly obtain a comparable level of herd immunity. "In other words, it will take a long time for us to reach the level of coexistence with this virus without causing a large number of deaths."
Under such circumstances, every country in the world has increased vaccination.
Zhang Wenhong introduced the situation in Israel, "Most of them are the original strains of the country’s own epidemic, which means that our vaccination today is still at the same level as the various mutant strains that may have escape risks in the world. Very effective position. Once again, the widespread vaccination of vaccines will become the most effective measure outside of our public health strategy."
Zhang Wenhong emphasized that if a disease has a very wide spread rate, we must be vaccinated. "From the perspective of the level of transmission and the fatality rate caused by the disease, the new crown must be vaccinated."
"For the future, we see the uncertain prevention and control of the new crown epidemic, so we still insist today that universal vaccination is the only decision we can outperform the virus." Zhang Wenhong said.
