Is it useful to vaccinate after getting COVID-19 vaccine? Will COVID-19 vaccine still infect COVID-19

Is it useful to vaccinate after getting a COVID-19 [SEP]. There are three levels of protection for COVID-19 vaccine. The first level is to prevent virus infection, the second level is to prevent disease, so that after infection, there are no symptoms or most of them are mild diseases, and no severe or a small number of severe diseases will not die. The third level is prevention, which means that there are certain symptoms after infection. However, because the body has immunity, the body has a low amount of virus, and will not infect others, so it is also possible to achieve the second and third level protection after infection with COVID-19 vaccine.

Do you want to check antibodies after finishing the COVID-19 vaccine

No need to check specifically. Antibodies are mainly divided into total antibody, neutralizing antibody, IgG, IgM, etc. In order to know whether the antibody after inoculation of COVID-19 vaccine is positive, it is necessary to detect neutralizing antibody of COVID-19. At present, only scientific research institutions can detect neutralizing antibody, and general hospitals cannot judge the titer of neutralizing antibody, so it is impossible to evaluate whether the immunization is successful. However, COVID-19 vaccine has been tested in the clinical research stage, and the results show that it can produce certain immunity after injection. Therefore, in general, it is not necessary to specifically test antibody immunity after vaccination.

Will COVID-19 vaccine still infect COVID-19?

Whether COVID-19 vaccine will still infect COVID-19 depends on whether the vaccinators have taken appropriate preventive measures; COVID-19 vaccination can reduce the risk of infection with COVID-19, but there is currently a variant COVID-19, and its infectivity is significantly increased. After COVID-19 mutation, the basic gene sequence and protein level of the virus have not changed substantially. At present, COVID-19 vaccination can prevent or reduce the risk of infection with COVID-19 mutation. However, it should be noted that after the COVID-19 vaccine is inoculated, it can not be completely prevented from being infected by COVID-19. The successor still needs to strengthen personal protection measures, wear masks, pay attention to hand hygiene, avoid personnel gathering, etc., and reduce the probability of COVID-19 infection.
