Question 1: What does it mean for the protection of the elderly people to protect this group?

Answer: From the current situation of the new crown epidemic situation and the popularity of mutant plants, we need to further increase the vaccination rate of the new crown vaccine for the elderly. New crown virus variants quickly and has always threatened the public's health. Although the total number of cases, the proportion of cases of elderly people is lower than that of young people, once the elderly are infected, the risk of severe illnesses and death is far higher than that of other people.

From the perspective of protecting the susceptible population, the effect of vaccination of new crown vaccines has significant effects on the occurrence of severe and death after infection. Our research and analysis of multiple epidemic -related information in domestic and foreign countries found that 2 doses and 3 doses of new crown vaccines can achieve high effects on preventing severe illnesses and deaths. Can reach more than 90%. Therefore, in order to protect all the elderly, we encourage the elderly who have not vaccinated taboos to vaccinate the new crown vaccine as soon as possible.

Question 2: After the vaccination of hypertension and diabetic patients, is there any feedback on the impact on the condition?

Answer: A suspected prevention of abnormal response monitoring system has been established nationwide. After vaccination, adverse reactions can be reported through this system. my country's vaccination has accumulated more than 3.4 billion doses. It is not higher than other vaccines, and more than 80%of the adverse reactions are general reactions, mainly for local pain, redness, hardships, and symptoms such as fever and fatigue. We analyzed the data of the monitoring system, and did not find that after the vaccination of the new crown virus vaccine, it had an effect on the condition of chronic diseases such as hypertension and diabetes.

Domestic new coronal virus vaccines have carried out some clinical research. Hypertension, diabetes, coronary heart disease, cancer, chronic respiratory disease and other basic diseases have no significant differences in safety and healthy people after vaccination of new coronary virus vaccines. The main adverse reactions are fatigue and injection Pain in the area, most of the adverse reactions are slight adverse reactions and are excessive.

Question 3: Some patients infected with the new coronal virus Omiroko mutant strains are very similar to a cold, milder symptoms, is it necessary for the elderly to get vaccines?

Answer: After some studies have confirmed, the propagation of the new crown virus Omikon's mutation has enhanced, and the virus mainly enters the human body in the upper respiratory tract, causing the symptoms of the upper respiratory tract. spread.

There is a large proportion of the elderly with one or more chronic diseases. After infection with the new crown virus, it will increase the risk of severe and death several times or even dozens of times. First, the body's immunity of the elderly has decreased. Once the virus is infected and the ability to resist the virus is weak, it is facing problems such as higher risk, heavier symptoms, and more difficult treatment. The proportion of diseases is higher, and these basic diseases are risk factor for severe and death in new crown. If the virus is infected, the symptoms of the original chronic disease will be more severe or more prone to complications.

The elderly vaccinate the new coronal virus vaccine, complete the whole process of vaccination and strengthen immunization, which can effectively prevent new crown and death. The elderly are critical and high -risk people infected with new coronary virus infection and high risk of death. It is necessary to vaccinate the new crown virus vaccine.

Question 4: Our country's epidemic prevention and control is done well. The old people feel that their legs and feet are not convenient or not. Is there no risk of infection? Is it necessary to vaccinate?

Answer: In 2021, most of the new crown epidemic in my country is limited to small areas, and the local area epidemic will be controlled quickly, but the mutation of the new crown virus Omikon is fast and hidden, which can easily cause community transmission. It is stable, but there are still cases and asymptomatic infections in some areas. There are still cases or viruses in our country abroad. Therefore, the risk of the elderly infected with new crown virus is very risky.

Although the elderly rarely go out, the family has the opportunity to infect the virus. The visitors and caregivers have the opportunity to infect the virus. People often relax their vigilance at home and have the risk of infecting the virus to the elderly. If the elderly are infected with viruses, the risk of severe illnesses and death will greatly increase. If the elderly do not go out, it may be heavier in his own disease, the body's resistance is weaker, and it requires key protection. If the elderly who are not inoculated, we encourage us to vaccinate the new crown virus vaccine as soon as possible.
