There are 85 new asymptomatic cases in Zhengzhou, 5 times the number of confirmed cases!

Although the overall coverage of the new crown vaccine in China is gradually increasing, there are still a few people who think that as long as the people around are vaccinated and herd immunity is formed , I will be safe!

If this sentence is placed in the first half of this year or last year, it seems to work.
However, the development of the epidemic is ever-changing.
Now, this sentence is no longer valid, but even more dangerous! The editor of Metz Medicine has to talk to this group of people!

What is herd immunity?

What is herd immunity? What is herd immunity? 

Taking the transmission R0 of the original strain of the new coronavirus as an example, it is true that 60% of the population is completely immunized (equivalent to 65% of the mRNA vaccination rate and about 80% of the domestic inactivated vaccine).
It is equivalent to everyone being safe
.

In the face of the Delta mutant strain, there is no such thing as herd immunity!

Taking the transmission R0 of the original strain of the new coronavirus as an example, it is true that 60% of the population is completely immunized (equivalent to 65% of the mRNA vaccination rate and about 80% of the domestic inactivated vaccine).

However, the new crown virus has now evolved into a devil.

R0 reaches 9, which means that even if vaccination in the population reaches 100%, there will still be a certain degree of infection and transmission! The so-called 60% or 70% herd immunity is no longer effective! ! Infect 

In China, the epidemic in the past week has also made people sweat

The fundamental reason why the Delta mutant strain is difficult to control is that the viral load of the infected person of the Delta mutant strain is extremely high
.

The Guangdong CDC study showed that the viral load of people infected with the Delta mutant strain was 1,260 times that of the original strain of the new coronavirus

The fundamental reason why the Delta mutant strain is difficult to control is that the viral load of the infected person of the Delta mutant strain is extremely high

More dangerously, CDC internal document written for the completion of the vaccination of people, when infected with Delta mutant, compared with an infected person is not vaccinated, the body will produce the same amount of virus, and infection The power is almost the same

When vaccinators are exposed to the new coronavirus, in addition to preventing most of the infection without getting sick, a higher proportion of asymptomatic infections will also be formed.

In other words, more people are infected without noticing it, and then unknowingly infecting family members and other close contacts

This is the situation faced by the UK and the United States recently, and it is also the situation currently facing China

The war against the epidemic has changed, thinking has changed, and the role of vaccines has also changed! The war against the epidemic has changed, thinking has changed, and the role of vaccines has also changed! 

Just like this, the CDC documents repeatedly emphasized: "The war has changed!"

But I don’t know if my friends have noticed that in the US CDC’s document, the Delta mutant strain is so terrible, with special emphasis on “the more breakthrough infections will be.
” Even in a new crown outbreak in Massachusetts, 74% of infected people have been vaccinated (346 out of 469 infected people have been vaccinated)

Judging from the case of the infection in Nanjing, China, most of the cases have also been vaccinated! This means that even if you have been vaccinated, you can easily get infected!

In the official media at home and abroad, "vaccine to prevent the infection and spread of new crown virus" is now rarely promoted, and more is "vaccine to prevent the risk of severe new crown pneumonia "
.

In fact, whether it is a domestic vaccine, an international mRNA vaccine, or other types of vaccines, it will be more and more difficult to prevent re-infection (on the one hand, the virus continues to mutate, on the other hand, the antibody titer in the body is declining)

However, both the East and the West vaccines have the same skill: to prevent severe illness! 

For the highly contagious delta virus, the US CDC's advice is to increase the vaccination rate and wear a mask

This is almost completely consistent with China's current measures

In China, the daily vaccination of vaccines exceeded 20 million doses per day at the peak, but then it rapidly dropped to only 7 million doses per day.
With the spread of the epidemic caused by Nanjing, the number of daily vaccination doses has been repeated again.
Increased to more than 15 million doses
.
This is consistent with the concept of strengthening vaccination in China
.
Moreover, the current domestic new crown vaccination has exceeded 1.
6 billion doses

The key
reason why the US CDC emphasizes that people who have not been vaccinated should be vaccinated.
The key problem is that the fatality rate is extremely low after vaccination .
Although the current epidemics in the United States and the United Kingdom are not as severe as they were at their peak, the number of people infected every day still reaches 2-4 million! However, the daily death toll has been extremely low.
At present , it is basically 1 death per million people .
At the peak, there are 10-18 deaths per million people, a drop of more than ten times!

The case fatality rate in the United States is 0.

Vaccination in the UK is higher and the mortality rate is very low
.
It is close to the 0.
1% level

Studies have shown that if the new crown vaccine is fully vaccinated, the case fatality rate is only 0.

This shows that although vaccination may not necessarily prevent the spread of the virus, it actually reduces deaths! Of course, the main reason for reducing deaths is to reduce severe illness!

On August 2, there were 61 new local cases and 23 asymptomatic infections in the interior of the country, which means that nearly 30% of the population are asymptomatic infections! These asymptomatic infected people also carry the virus and spread the virus unknowingly! If you count mild cases, maybe this ratio will be even higher!

Correspondingly, people who have not been vaccinated have become more dangerous, or more likely to be infected with the new coronavirus than ever before
.
It was originally hoped that through the establishment of herd immunity by vaccinators to block the epidemic, so that those who have not been vaccinated can benefit from it; now it is completely different.
The vaccinators continue to be infected but they are not serious, and the vaccinators continue to spread the virus, and a large number of them are not.
Those infected with symptoms spread the virus unknowingly

Of course, some people have said that if you get vaccinated, don’t you still get infected? ! Yes, although vaccination cannot prevent infection, after the body’s immune system has a memory of the virus, once infected, it will quickly adjust the body’s immune function, so that the infection is no longer serious, just like a common cold or flu, which is itself a problem.
Kind of protection
