Academician Wen Yumei answered questions about the elderly inocating the new crown vaccine

Xinhua News Agency, June 30 (Reporter Zheng Juntian, Gong Wen) "Do you know how old I know?" At 9 am on the 29th, Wen Yumei, a famous virusist and academician of the Chinese Academy of Engineering, came to Shanghai Hongkou District, Shanghai The Bund Street Community Health Service Center vaccinated the needle vaccine. When waiting for vaccination, she talked kindly with the elderly next to the elderly: "I'm almost 90 years old, and we are here to strengthen the needle. Our elderly must take vaccines. To strengthen the needle. "

Is it necessary to strengthen the needle? What is the effect of mixing?

"Taking advantage of the good weather in the morning, I came here to vaccinate the third crown vaccine." Wen Yumei told reporters that the first two needles were vaccinated with the vaccine, and the third inoculation was the restructuring of the new crown virus vaccine. "It is possible to strengthen the needle to fight the same source, and it can also be used, but the experiment has proved that the effect of being heterogeneous is better, because the body immune factors and cells it mobilize are different. ","

Wen Yumei said that it is very necessary to strengthen the needle. "People who have already hit the first two needles have been for a long time. The immune system will forget the virus. To enhance the needle to enhance the memory of the immune system." She made an analogy. Strengthening immunity is like "deepening impression" in interpersonal communication. The function of strengthening the needle is to deepen the "memory" of the body to the virus appearance and "strengthen" immunity.

Can the elderly with chronic disease be vaccinated? When is it appropriate?

At present, many communities are carried out new crown vaccination work, but some elderly people still have concerns because they have basic diseases. Wen Yumei explained that if the elderly have chronic diseases such as hypertension and diabetes, the severity of chronic diseases must be first. "I have been suffering from hypertension and diabetes for more than 20 years. After taking the medicine in the morning, blood pressure has been controlled. From the perspective of relevant indicators, it is even better than young people. If the blood pressure of the elderly is very unstable, then I recommend that the blood pressure is stable in the blood pressure stable. Severe when you are. But you ca n’t fight because you are sick. If the elderly are very stable within 1 to 2 months, they can be vaccinated. "Wen Yumei emphasized that everyone's situation is different. The vaccine cannot be "one -size -fits -all". Specific analysis should be analyzed in detail, especially for elderly friends to take the new crown vaccine in time according to their own situation.

Academician Wen Yumei advocated that it is necessary to understand the necessity of vaccination from the perspective of the elderly.

The new coronal virus is constantly mutated. Is vaccination effective?

Many citizens are concerned that the new coronal virus is constantly mutating. Is it still useful for vaccines now? Wen Yumei said that from the current point of view, the vaccine is not invalid, but the effect of reducing results, but it is still effective. Wen Yumei believes that Omikon's mutation strains are very special and change, but the change is inseparable. "The mutation of the new crown virus is partial, but it has not changed overall. Therefore, after the vaccination of the new crown vaccine, people may still be infected, but the important point is to reduce the risk of severe illness, which is especially important for the elderly."

At present, Shanghai is accelerating the new crown vaccine in the elderly. Some "vaccination teams" enter the community, enter the nursing home, and enter the residence. Yang Yonghua, director of the North Bund Street Community Health Service Center, said: "For the elderly who have the willingness to vaccinate but are inconvenient to go out, we provide uninterrupted on -site services from Monday to Sunday."
