The elderly need to "receive all the new crown vaccines"
2021-12-01
65 times! 150 times! 370 times! Novel coronavirus pneumonia is the three figure from the US CDC. It is based on the analysis of the new crown pneumonia epidemic in the United States, compared with the age of 18 to 29, the risk of death increased by 65 to 74 years, 75 to 84 years old and over 85 years old. At the joint prevention and control press conference of the State Council on November 30, Zheng Zhongwei, director of the science and technology development center of the National Health Commission, said that according to the statistics of various countries, the global death toll is mainly over the age of 70. How can novel coronavirus pneumonia be severely reduced in the elderly? "The risk of novel coronavirus pneumonia in the elderly is significantly lower than that of the unvaccinated elderly. However, 50 million of the elderly in China are not vaccinated against COVID-19," Zheng Zhongwei said. If the vaccination work of these 50 million groups is not promoted quickly, once the control is relaxed, severe and death will occur, causing major social problems. 200 million old people have been vaccinated, and the vaccination rate is insufficient in some areas Data show that there are 264 million people over the age of 60 in China, and 206317000 people have been vaccinated so far. At present, about 50 million of the elderly (about 20%) are not vaccinated with COVID-19 vaccine, which is equivalent to the population of medium-sized countries. According to the data of the U.S. Centers for Disease Control and prevention, the current vaccination rate of new crown vaccine for people aged 65 and over in the United States has reached 86.1%. According to Japanese official data, 86.5%, 87.83%, 92.62% and 94.35% of Japanese people aged 60-64, 65-69, 70-79 and over 80 have completed the whole course of vaccination respectively. "In comparison, the proportion of new crown vaccination in China's elderly population is relatively low," Zheng Zhongwei said. The vaccination rate of people aged 80 or above in some provinces and cities is less than 30%. The vaccination rate of the elderly population over 70 years old is less than 50%. However, due to the highest risk of serious illness and death after infection with COVID-19, the new crowns vaccine should be accelerated. "It is a misunderstanding that many elderly people think that if they stay at home or in remote rural areas, the risk of infection will be reduced." Zheng Zhongwei reminded that with the increasing proportion of young people vaccinated, they will show mild or asymptomatic infection. When reuniting with the elderly on New Year's holidays, there may be a risk of taking the virus home to infect the elderly. Therefore, we must make sure that all the elderly should receive it. The mortality of the elderly is higher, and immunization should be strengthened "The World Health Organization reports that COVID-19 has caused the mortality rate of the whole population to be 2%, while the mortality rate of the elderly has been reported 50% or even higher." Wang Huaqing, chief expert of China's CDC immunization program, explained that there are two important factors leading to severe and death: one is age and two is the underlying disease. Age, with the increase of age, thymus and other immune organs atrophy, immune ability decline, making it difficult to resist COVID-19 attacks. Most novel coronavirus pneumonia deaths are caused by organ failure. The superposition of basic diseases such as hypertension and diabetes will greatly increase the risk of death caused by severe diseases. Wang Huaqing said that many elderly people have one or several basic diseases. After the superposition of several causes, the risk of severe illness and death is relatively high. Therefore, this part of the population needs to be vaccinated with the new crown vaccine. For the elderly with basic diseases, vaccination can be carried out in the stable period, or consult the vaccination doctor or clinician. "After the old people are vaccinated with the new crown vaccine, the antibody level drops rapidly." Wang Huaqing said that compared with other adults, the protective efficacy of the new crown vaccine is decreasing with the extension of time, and the decline is greater for the old people. Wang Huaqing said that countries around the world that have strengthened immunization have a common focus, that is, the elderly. He hopes to improve the immunization level of the elderly and improve the protection level of the elderly by strengthening immunization. 500 million elderly people have been vaccinated to prove their safety The COVID-19 vaccine currently used in China has carried out phase I, II and III clinical trials of the whole population, including the elderly, before obtaining approval from the relevant agencies for conditional listing or emergency use. In addition, the number of vaccinations of COVID-19 vaccine in China over 60 years old and above has exceeded 500 million doses. The vaccine shows good safety in more than 500 million doses and vaccination in the elderly, and the adverse reactions of the elderly are slightly lower than that of adults. Zheng Zhongwei said that there are 106 elderly people who have been vaccinated with the new crown vaccine abroad, and those who have the highest vaccination age of COVID-19 vaccine in China are 106 years old. All of them show good safety. The data show that the overall side effects of China's main vaccines are low. The proportion of fever after vaccination is about 17.61/1 million, which generally does not need to be treated. Severe allergic reaction is less than one in ten million, which can be recovered as long as it is treated in time. Zheng Zhongwei reminded us that in addition to the cases of allergic shock or laryngeal edema that have been vaccinated, and have a fever or infectious diseases and neurological diseases, the elderly can be vaccinated with COVID-19 vaccine.
