As of midnight on March 20, a total of 74.956 million doses of the new corona vaccine had been reported nationwide. The domestic epidemic has been effectively controlled, why is it necessary to be vaccinated? Can people choose their own vaccine brands? Do cancer patients and pregnant women need to be vaccinated? What are the possible adverse reactions after vaccination?
On the afternoon of March 21, the Joint Prevention and Control Mechanism of the State Council held a press conference to respond to the safety and efficacy of the new coronavirus vaccine.
There is still a risk of infection after curing or vaccinating the new crown. The entry control is implemented according to the actual conditions of the different countries.

Feng Zijian, deputy director of the China Centers for Disease Control and Prevention, said that the entry of people or goods from highly endemic areas still poses the risk of spreading within my country. Even those who have been infected or vaccinated in high-endemic countries cannot completely avoid infection. Although the risk of disease will be greatly reduced, there is still the risk of reinfection. After entering the country, if prevention is not good, it can also cause spread within the country.
Currently, regardless of the vaccine used in any country, the effect of preventing a serious disease is better than that of a mild disease. Several mutated viruses of particular concern and concern have also emerged abroad, which have had some impact on the protective effect of the vaccine.
Taking these factors into account, the normalized prevention and control work of my country at this stage should continue to adhere to various measures of importation of external defense and recovery of internal defense. According to the global epidemic situation and the global inoculation situation, some measures need to be adjusted and optimized in an orderly manner.
In terms of preventing foreign imports, we will continue to strictly implement prevention and remote control measures, and do a good job in sanitary quarantine, centralized isolation and observation, and nucleic acid testing for entry personnel. For the time being, vaccinators will not be exempt from testing and isolation measures to effectively block illegal border crossings and insist that characters be on the same defense.
At the same time, it will be considered to implement differentiated policies for the issuance of visas, flights and the number of people entering the country according to the level of vaccination and the epidemic situation in the different countries. At the same time, pay attention to the international progress of vaccine passports and adjust prevention and control measures in a timely manner when national people have achieved a high level of immunization protection and are feasible.
“The epidemic is far from me” is a mistake.
He Qinghua, first-level inspector of the CDC of the National Health Commission.China Net Zheng Liang / photo“Here I again recommend that everyone receive the new coronavirus vaccine as soon as possible to get immunity and protection as soon as possible.”
Mr. He Qinghua, CDC’s first-level inspector of the National Health Commission, pointed out that the new corona epidemic is still in the global epidemic and no one can be alone. Vaccination is the most effective means of preventing and controlling the new corona epidemic. Although the epidemic situation in my country has been effectively controlled, “the epidemic is far from me and the urgency of vaccination is not too strong” is still a misunderstanding.
He Qinghua said that the epidemic in my country has not formed a large-scale outbreak and that the proportion of people who have acquired immunity due to infection with the new corona virus is relatively low. Therefore, the new corona vaccine must be vaccinated to allow more people to get immunity and protection.
Annual vaccine production can meet the vaccination needs of all people. The selection of vaccines will be organized by each province and city.

According to Mr. Mao Junfeng, Deputy Director of the Consumer Goods Industry Department of the Ministry of Industry and Information Technology, my country currently has 5 vaccines, 3 inactivated vaccines, 1 adenovirus vector vaccine and 1 recombinant protein vaccine. For emergency use.
As the work of increasing production and capacity progresses, vaccine production increases gradually. Compared to the beginning of February, the current vaccine production has greatly improved and the next step will be further improved.
He Qinghua, a first-level inspector of the Health Commission’s Office of Disease Control and Prevention, mentioned that some areas have started to vaccinate the new corona vaccine for people over 60 with better physical conditions. At the same time, vaccine research and development units are also accelerating research and development, which once clinical trials have obtained sufficient safety and efficacy data, will carry out large-scale vaccination of the elderly older than 60 years. In the next step, we will continue to promote vaccination, gradually expanding the coverage of the population and allowing as many people as possible to be vaccinated.
Currently, there are 4 new coronavirus vaccines on the market in China. Can people choose different vaccine brands on their own? He Qinghua said that since the types of commercialized vaccines purchased by provinces and cities may be different, everyone should be vaccinated as soon as possible according to the unified arrangement of the province and the city. As for the question of whether vaccines produced by different companies can overlap or substitute for vaccination, more research is needed.
Cancer patients and pregnant women have a higher proportion of severe cases of new coronary artery disease than other groups that need to be vaccinated, but this needs to be studied.
Currently, who cannot get vaccinated?
He Qinghua said that the four vaccines currently on the market have clearly defined contraindications to vaccination in the instructions: those who are allergic to the ingredients contained in the vaccine and those who have had severe allergic reactions such as acute allergic reactions, angioedema and dyspnea. with uncontrolled epilepsy or other neurological diseases, those with a history of Guillain-Barré syndrome, women during pregnancy or lactation, etc.
When vaccinating, it is necessary to truthfully inform the doctor conducting the vaccination about the health status, past medical history, allergy history and other information, including the history of chronic diseases, so that the doctor can make a comprehensive evaluation and judge whether it is suitable for vaccination. Also, you should report your current status to your doctor when you get vaccinated.
Wang Huaqing, chief expert of the immunization program at the Chinese Center for Disease Control and Prevention, said that according to the results of previous studies, cancer patients and pregnant women have a higher proportion of serious diseases and death rates. than other groups, so they should be vaccinated.
However, due to the fact that there is still relatively little systematic research data on the use of vaccines for cancer patients and pregnant women, from a prudent perspective, pregnant women are not vaccinated. Wang Qinghua said that with the accumulation of investigative data in the subsequent period, the temporary taboo will change and the strategy will be adjusted.
He took as an example the flu vaccine, which could not be given to pregnant women. However, due to the relatively high incidence of serious illness, the rate of admission to the intensive care unit, and the subsequent death rate of pregnant women after being infected with influenza, pregnant women have been switched to the population. priority for influenza vaccination.
Wang Huaqing also mentioned that if a pregnancy is found after vaccination, no special medical measures are recommended, including termination of pregnancy. He suggested that regular monitoring and inspections during pregnancy should be carried out in the aftermath.
At present, my country vaccinates mainly people over 18 years of age, and more considerations will be made according to the needs of prevention and control of epidemics and the improvement of data from clinical trials of vaccines. At that time, relevant research on simultaneous vaccination or combined immunization will be carried out to determine whether newborns and infants can be vaccinated at the same time.
Local reactions like redness, swelling, induration, and pain will heal on their own. Suspicions of serious adverse reactions from the new corona vaccine will be followed.

Wang Qinghua, chief expert of the immunization program at the Chinese Center for Disease Control and Prevention, said that people allergic to food, pollen, penicillin and other drugs can be vaccinated. However, if there are severe allergies after vaccination, follow-up vaccination cannot be done.
Wang Huaqing also mentioned that most allergies are acute allergies, which occur within 30 minutes of vaccination. One of the purposes of observing the scene for 30 minutes is to prevent other injuries caused by acute allergies.
“The results of this new corona vaccine in preclinical trials, emergency use and post-marketing follow-up show that its adverse reactions are similar to the results of previously used marketed vaccines, and there is no abnormal situation.”
Wang Huaqing said that current local reactions include pain, redness, swelling and induration after the injection, which do not require treatment and will heal on their own. Headache, fatigue, and low-grade fever may occur in systemic reactions. The adverse reaction now reported is a suspected abnormal reaction to vaccination, which may be a suspected adverse reaction. The suspected more serious adverse reaction will be investigated at follow-up.
“In the course of the investigation, additional inspections are needed for some cases, to understand their implantation history, to understand the occurrence of the entire disease, and finally the team of experts will make a diagnosis. This requires a process and a certain amount time. In the follow-up, we will gradually carry out continuous monitoring and related evaluations, “said Wang Huaqing.
