Therefore, the public also needs to do the current full-course vaccination and booster vaccinations.

On the same day, the Joint Prevention and Control Mechanism of the State Council held a press conference on the urgent and detailed situation of epidemic prevention and control.
Wang Huaqing said at the meeting that the Omicron variant makes the spread of the new coronavirus faster, more infectious, and more insidious. In this case, the current new coronavirus vaccine is effective in preventing severe illness and preventing death. It is clear and significant, and the preventive effect will be better after completing the whole course and booster vaccination.
"The current research on the Omicron strain vaccine is to hope that we will be able to add a means in the process of responding to the new coronavirus in the future. Although the Ormicron variant vaccine has entered clinical trials, it will take time to determine its research results. Wang Huaqing said that the Omicron strain is still prevalent around the world. If the elderly and people with underlying diseases do not complete the full course and booster vaccination, once the epidemic occurs, more severe cases will occur, thereby increasing the burden of medical treatment. Therefore, it is imperative to complete the whole course of vaccination as soon as possible, and to complete the booster vaccination as soon as possible.
It is believed that Omicron will acquire natural immunity after infection.
In this regard, Wang Huaqing said that the new coronavirus is in the process of mutation and evolution, and human understanding of the virus is also deepening.
"After being infected with the virus, in theory, there will be natural immunity, but I think this is not the choice we should make at the moment."
He said that the Omicron variant can still cause severe illness and death, especially in people with chronic diseases and the elderly. It is a "dangerous choice" to obtain immunity by natural infection alone, and the new coronavirus vaccine has been preventing severe illness and death since its application. The effect is still very clear.
Wang Huaqing also said that the Omicron strain has undergone a considerable mutation, and the immunity generated by natural infection has great uncertainty.
He also cited recent studies showing that the neutralizing antibody level induced by the Omicron variant in the unvaccinated population is lower than that in the vaccinated population, the antibody induced is not broad enough, and the protection against infection by other variants is limited. .
