Are vaccines effective against new viruses?

Introduction: As we all know, in 2020, China suffered a serious new crown pneumonia epidemic, and this epidemic Chinese people are united in a city, do not believe rumors or spread rumors, and many people have come to Wuhan overnight, reflecting the great unity spirit of the Chinese people. But through the continuous efforts of the Chinese, the new crown epidemic was finally controlled, and according to the new crown epidemic, the country also developed a vaccine to prevent it.

Next, let me take you to understand whether the new crown vaccine has an effect on the new virus. <>

1. The new crown vaccine research and development process.

As soon as the new crown epidemic appeared, the country set up a relevant scientific research team to carry out the research and development of the new crown vaccine, and after the continuous testing and research and development process of these scientific researchers, the new crown vaccine was finally developed. After the new crown vaccine was developed and put into use, many people believe that the new crown vaccine has a great effect on preventing the new crown epidemic. China has also distributed the new crown vaccine to its citizens for free, so that the citizens can get vaccinated faster.

China has also donated vaccines to other countries for free as a way to help other countries emerge from the pandemic. <>

2. The effect of the new crown vaccine on the new virus.

As the name suggests, the new crown vaccine is to prevent the new crown epidemic, and the virus produced by the new crown epidemic is a new virus that we have not found before. However, the new crown vaccine is also very strong against this new virus, which can minimize the chance of people getting new crown pneumonia. The new crown vaccine developed by China is also very small for the human body, and many people have no adverse reactions after vaccination, which proves that the new crown vaccine has a great effect on preventing new viruses.

3. Pandemic prevention measures.

In most people's minds, as long as they are fully vaccinated, they don't need to wear a mask when they go out. In fact, this practice is incorrect, even after vaccination, people should still wear masks when going out and keep a distance of one meter away from **, which is also an important way to prevent and control the epidemic, and can also reduce the chance of being infected with the new crown virus and protect their health.

The vaccine is definitely effective against the new virus, but the virus mutates quickly, but even if you are vaccinated, the symptoms will not be too serious.

The vaccine is also effective against the new virus, but it is not possible to completely avoid infection, but it can reduce symptoms.

Vaccines are effective against new viruses, but vaccines need to build herd immunity to be effective.

It is effective, and it can enhance the body's immunity, but we still have to wear masks when we go out, and we should remember to disinfect, and we should stay away from some crowded places.

There will still be some effects, which can play a certain preventive role, but you should also wear a mask when you go out in normal times, and don't take it lightly.

The domestic new coronavirus vaccine is a vaccine developed based on the original new coronavirus, which has little effect on the mutated virus, and the corresponding vaccine needs to be redeveloped.

This mutation of the virus is unlikely to lead to vaccine failure. The role of the vaccine is to let immune cells recognize the virus in advance, and the current mutation does not affect the recognition of the virus by immune cells.

Not necessarily, after all, such a vaccine is also aimed at the virus before the mutation, and further investigation and research are still needed after the mutation.

The vaccine helps the body fight the virus, and this is how it works:

1.Inject less virulent or killed germs into the body that are harmless but similar to the ones that make you sick.

2.The white blood cells in the body fight these germs and record them with antibodies. In this way, your body is equipped with defenses against this germ.

3.When really harmful germs enter the body, the body is able to destroy them before they become sick.

4.Unfortunately, there is still no vaccine against the common cold.

Wang Huaqing, chief expert of the immunization program of the Chinese Center for Disease Control and Prevention, said that the virus is one of the simplest organisms, and its proliferation depends on living cells. During the process of proliferation, the virus mutatesMost variants do not affect the pathogenicity of the virus, the sensitivity of detection reagents, and the effectiveness of vaccines

According to the latest information released by the World Health Organization, from the global surveillance of new coronavirus mutationsThere is no evidence that the virus mutates to render existing COVID vaccines ineffective

The World Health Organization's global network of COVID-19 laboratories includes a dedicated SARS-CoV-2 virus mutation and evolution working group, which is rapidly detecting new mutations of the virus and assessing their possible impact in a timely manner, which will also provide early warning and scientific analysis for the development and application of subsequent vaccines.

Vaccine R&D companies have carried out cross-neutralization ability testing and evaluation of vaccine immune sera for the currently collected domestic and foreign variants, and have not found that the neutralizing activity of China's conditionally marketed new coronavirus vaccines against variants has decreased significantly, nor has it been found to have a significant impact on the protection rate of variants, and relevant companies will continue to carry out follow-up studies.

According to the latest information released by the World Health Organization, from the global monitoring of new coronavirus mutations, there is no evidence that virus mutations will make existing new coronavirus vaccines ineffective.

I think so, because the vaccine is based on the original virus, and it has the best effect on the original virus, and once the virus mutates, the vaccine is likely to be ineffective, or the effect is not obvious.
