The vaccination rate continues to increase, and it will become easier and easier to deal with the virus

At present, the spread of mutated strains of the new coronavirus "Delta" around the world is increasing
.

At 9:30 pm on June 27th, Zhang Wenhong, director of the National Medical Center for Infectious Diseases and director of the Department of Infectious Diseases of Huashan Hospital affiliated to Fudan University, answered the above questions when he was a guest on the STV News Comprehensive "Night Line Appointment" program
.

Zhang Wenhong said that "Delta" is currently the fastest virus in the world, but no matter how fast it runs, it is still a coronavirus and has not become a new virus.
It is faster than the original "Alpha" that was popular in the UK.
The strain is about 60% faster
.

He cited, for example, that in Guangzhou, through some non-drug measures and expanded testing, the epidemic was finally brought under control
.

"Delta" did not cause the new coronavirus to become a new virus.
What does it mean? Zhang Wenhong emphasized that this means that the original prevention and control measures against the virus are still effective, including vaccination
.

Zhang Wenhong enumerated the difference between the flu vaccine and the new crown vaccine.
"We need to inject the flu vaccine every year.
That's because the influenza viruses that circulate are different every year.
This is mainly because the influenza virus will undergo reorganization and the subtype will change.
For example, from H1N1 to H3N2, then the original vaccine is not effective against it, but the coronavirus is not.
The original vaccine is still effective against it
.

Regarding the "Delta" mutant strain, Zhang Wenhong further stated: "The virus is still that virus.
It has become more cunning, but it is still under the guns of the hunters.
We must continue to be vigilant, maintain the original strong protective measures, and strengthen the vaccine.
With vaccination, we have the ability to control the spread of the virus.
As the penetration rate of vaccines gets higher and higher, the possibility of us winning this war will increase
.

What role does vaccination play in the prevention and control of the epidemic? What is the vaccination rate required to build an effective immune barrier?

In this regard, Zhang Wenhong used "catching mice in a ceramic shop" as an analogy, "We have to let the mice encounter obstacles everywhere in the process of running, and they can't get out.
Let the mice run into mazes, and the mazes are like those who fight.
People who have been vaccines, the more mazes we encounter, the more likely we are to catch it easily
.

He said frankly that from the current point of view, the vaccination rate should reach more than 80% of the entire population, but now the vaccination rate is not enough.
People under the age of 18 have not yet been hit.
It is still difficult to achieve, but we must move in this direction.
Let’s go, let more people get vaccinated, so that we can set up more obstacles to the spread of the virus.
In addition, we will also have some auxiliary epidemic prevention measures, such as wearing masks, not getting together, washing hands, etc.
, in addition to our The anti-epidemic force can make up for the "gap" left by the spread of the virus, such as finding the source of infection and isolating it in time, and finding close contacts to expand testing
.

"Except for vaccines, there is no better way to slow down the spread of the virus
