What are the benefits of the new crown vaccine?

When it comes to the benefits of vaccines , in fact, we should first talk about the origin of vaccines-influenza virus
.

The origin of the vaccine can be traced back to the Spanish flu in 1918.

Vaccine development stems from a pandemic of influenza virus

As a kind of virus, influenza is a self-limiting disease after infecting the human body; this global new coronavirus is also a self-limiting disease in general
.

Generally speaking, self-limiting diseases mainly rely on the body's own immunity, and most people have passed the first anti-antibody.

Therefore, in order to cure the flu, it is necessary to produce vaccines on a large scale, and prevent and treat the virus before it becomes infected
.

The cultivation of the swine flu virus is a problem, because flu vaccines need to be mass-produced first

But with the mass production of influenza vaccines, influenza viruses have also evolved
.

Therefore, we can see that the annual influenza vaccine will be continuously updated with the mutation of the influenza virus

The spread of the new coronavirus is similar to the "large" flu, and the vaccine is still the ultimate means

People often say that they don’t know when the next flu will come, and they don’t know how it will come
.

However, for this new type of COVID-19 coronavirus, is it not a brand new "large" flu? And for the new type of coronavirus in 2020, is it not a brand new flu? Therefore, for the prevention and treatment of this new flu, vaccines are still the ultimate means

The popularity of vaccines is closely related to group resistance, and group barriers are the most important

But what we want to mention here is why the flu virus continues to occur and discover in various cities after the vaccine is produced? It is because influenza virus is constantly mutating and combining every year.
It cannot be completely prevented.
New mutant viruses cannot be prevented by old virus vaccines.
Therefore, vaccines should also evolve continuously as the virus mutates.
And improve, until the new virus is constantly extinguished
.

Therefore, if you want to prevent influenza, you must not only be vaccinated, but also wear a mask during the season of high incidence of the virus to avoid contagion, wash your hands frequently, and take personal hygiene protective measures

       What's the point that antibodies from the new coronavirus can be passed from the mother to the offspring?

       Recently, including China, Spain and other countries, it has been reported that children carry antibodies to the new coronavirus right after they are born-that is, there have been newborns in the world who have antibodies to the new coronavirus at birth
.

This means that the ability of pregnant women to resist the virus can be inherited to the offspring to a certain extent

       summary

       In short, from the global pandemic of the new type of coronavirus pneumonia, we will never be able to determine the time or location of the next newly discovered infectious disease outbreak, as well as the specific types of infectious pathogens that pass through the virus.
Therefore, for humans Precautions Therefore, the prevention of infectious diseases and the development of vaccines cannot be overemphasized
.

The vaccine may lead to the end of the new coronavirus, but in terms of the current global spread of the new variant of the new coronavirus , this road is dangerous and long
