The fourth dose of the new crown vaccine has not yet begun in our country.
At present, the National Health Commission has not yet requested a fourth dose of the new coronary vaccine for our population.
The concept of the fourth dose of the new crown vaccine comes from an Israeli study, which suggests that the fourth dose of the new crown vaccine can increase the number of antibodies in the body by five times. However, the trial is still ongoing and data on the effectiveness of the vaccine is not yet clear. Considering the development of the epidemic and the different health policies in different regions, the fourth dose has not yet been administered in China.
As a matter of fact, the third booster shot of the new crown vaccine can effectively raise the antibody titer in the body, which has a very good immune protection effect on the population. Therefore, it is recommended that all people who are eligible for the new crown vaccine should receive it in time to strengthen the immunization effect.
The fourth vaccination time is not clearly proposed, so the general public also need to do a good job of protection, wash your hands diligently, more ventilation.
