I have been vaccinated before, and I have developed antibodies, can I still be infected through bloo

4 - 1) Hepatitis B vaccine injection is immune; (2) Previous infection.

Clause. Two or five were positive, and the remaining three were negative. It means that you have been vaccinated against hepatitis B, or you have been infected with hepatitis B virus, and you have immunity.

The above is a simple list of some common manifestations after hepatitis B virus infection, for individuals, there may be other different combinations of manifestations, or in the outcome, so if you encounter an atypical combination, do not worry, it is recommended to retest again after a period of time, and generally atypical conditions will not last long. Your second positive means that you have antibodies to hepatitis B virus, I don't know how much? If you have more than 10 IU (called moles), you do not need to be vaccinated.

If it's not enough, it's better to fight!

What kind of illness are you talking about?

The vaccine should also be divided into diseases.

The way of infection is also different.

Why are some people still infected after vaccination? 1. Why are some people still infected after vaccination? In our country, the vaccination rate has also risen sharply, but in this case, there are people who are still infected with the new crown virus after vaccination, and the infected person is still an inspector in a hospital, and the inspector is usually responsible for testing the new crown pneumonia specimens, so he is likely to be infected when he comes into contact with the virus during the testing process. This also shows that vaccination does not protect 100% of everyone, and no vaccine in the world can guarantee 100% protection efficiency, so this is also a very normal situation.

2. Can I do without protection after vaccination? Some people think that now the vaccine is the only effective way to protect all of us, so many people feel that they have a layer of protection on their bodies after vaccination, and they will think that they are safe no matter how they go, because they feel that after they have antibodies, the new crown virus will have no way to invade their bodies. In fact, this kind of thinking and practice is very wrong, because even after vaccination, it is necessary to do a good job of personal protection, on the one hand, because some people do not produce antibodies after vaccination, and more importantly, even if some people's antibodies are not enough to resist the virus, so personal protection should be carried out after vaccination, so as to ensure that nothing goes wrong.

3. How can we truly protect ourselves from infection? For all of us, if we want to truly protect ourselves from being infected by the virus, the best thing to do is to get vaccinated, and then continue to follow the epidemic prevention and control measures to carry out personal protection, avoid gatherings, and avoid cross-infection, so that we can not be infected by the virus. As the saying goes, if you are not afraid of 10,000, you are afraid of what happens, for the sake of our own health, we must also be vigilant, and we must not take it lightly at any time, so as not to be invaded by the virus.

The new coronavirus mainly plays a preventive role, and its purpose is to protect most people from inconvenience, especially for severe patients. No drug can guarantee the success of everyone's vaccination, and there are still a small number of people who fail to protect after vaccination, which is normal because everyone's individual situation is different, and other reasons may lead to post-vaccination failure, which can lead to infection.

First, the previous large-scale clinical trials have confirmed the protective efficacy of the new crown vaccine, and the protective effect will not change due to the infection of individuals with the new crown virus; Second, the vaccine is to protect most people from getting sick, especially the effect on preventing severe disease is better, and the prevention of severe disease is more efficient; Third, the results of foreign assessments also show that a small number of people have protection failure after vaccination, and the reasons for protection failure will be studied and investigated in the future.

Vaccination against COVID is not 100% anti-infection. Some people have only received the first shot, and at this time the protective layer has not yet formed, so they will become infected.

After vaccination, it does not mean that 100% of people are not infected, and the vaccine can protect more than 90% of people, but if you are in an environment with bacteria for a long time, you will definitely still be infected.

Because these people do not do their own protection after vaccination, and they usually do not pay attention to hygiene and disinfection, they will still be infected.

Because everyone's constitution is different, some people have a weak constitution after vaccination, and their body does not produce antibodies, so they will be infected.

This is because these people have produced antibodies in their bodies, and it may also be because the vaccinated people have a particularly weak constitution and low immunity, so they will be infected.

It shows that the vaccine has no effect on it, and it may also be because he has come into contact with a lot of people who have the epidemic, and it is likely that the effect of the vaccine has not yet had an effect.

It is because these people feel very safe after being vaccinated, so they do not wear masks when they go out, and they do not take relevant precautions.

There is an urgent need to develop mRNA or a better vaccine!!
