7, the State Council joint defense joint control mechanism held a news conference to introduce the situation of epidemic prevention and control and COVID-19 vaccination. At the p>

meeting, the economic news reporter of twenty-first Century asked: according to public information, some countries in the world have clearly provided COVID-19 vaccine to strengthen vaccination for the public. What is China's consideration in this regard? p> < p > Shao Yiming, member of the expert group of the vaccine R & D special class of the scientific research group < / P > < p > Shao Yiming, member of the expert group of the vaccine R & D special class of the scientific research group: since last year, the global vaccination of Xinguan vaccine has exceeded 3 billion. In order to better deal with epidemic prevention and control, many countries are considering strengthening vaccination. At present, after vaccination, the antibody level of all vaccines will decline over time, but the immune memory still exists. Therefore, once the virus is infected, it can stimulate a strong memory response in a very short time, almost a week, and the antibody will rise significantly. To strengthen immunization, countries are conducting research. At present, there is not enough evidence to show that the third dose of vaccination is needed for the whole population < p > according to the preliminary observation, it is not necessary to strengthen needle vaccination for the general population who have completed immunization within one year. However, for the elderly and patients with basic diseases who have completed immunization for more than 6-12 months and have weak immune function, as well as the personnel who need to work in high-risk areas due to work needs, whether it is necessary to carry out booster vaccination and when to carry out booster vaccination are being studied < p > according to a large number of previous scientific research experiments and international research experience, in order to ensure the safety and effectiveness of vaccination, vaccines of the same technical route are generally used for enhanced vaccination when necessary. However, whether vaccines with different technical routes can also be used is still a question of scientific exploration. At present, there is no consensus in the scientific and technological community, so a large number of clinical studies are being promoted < p > at present, our country is making great efforts to promote the vaccination of new crown vaccine. In order to quickly restore the normal life state and order of our country and return to normal economic life, I hope you will start from the overall situation, actively vaccinate Xinguan vaccine and participate in our vaccination work in the second half of the year
