Beijing reported a critically ill patient on May 8, 79 years old, who had not completed two doses of the new crown vaccine.
For a period of time, the severe, critical and death cases of the new crown seem to have “found” a group of people by chance. Their common characteristics are: old age and incomplete vaccination of the new crown.
Such “coincidences” appear frequently in the statistics of many countries and regions. How often is it? What are the odds of a seemingly “coincidence”? Relevant experts sorted out three major aspects of comparative data for Science and Technology Daily reporters.

“In fact, no matter what kind of infectious disease, there will always be the elderly among the key groups that are most easily invaded.” Wang Huaqing, chief expert of the immunization program of the Chinese Center for Disease Control and Prevention, gave two aspects at a press conference. The reasons are: first, the immunity of the body declines with age, and second, the elderly have more underlying diseases, and the impact is more serious.
Vulnerability is “a certainty”, so how fragile is it compared to young adults? Many countries have done comparative studies in this regard.
Zheng Zhongwei, leader of the vaccine research and development team of the scientific research team and director of the Science and Technology Development Center of the National Health Commission, cited research data from the US Centers for Disease Control and Prevention to give a detailed stratified comparison-compared to 18-29 year olds, 65-74 year olds had a 4-fold increased risk of hospitalization and a 65-fold increased risk of death, and 75-84 year-olds had an 8-fold increased risk of hospitalization and a 140-fold increased risk of death, 85-year-olds In the above group, the risk of hospitalization was increased by 12 times and the risk of death was increased by 340 times.
The risk of death is increased hundreds of times, and many people may not have a specific concept. To use a cross-border analogy, a meteorite the size of a football field hits the earth. It happens once every 3,300 years on average, and people will never encounter it once in several lifetimes. If the impact risk increases by 300 times, then it will happen once every ten years, and a person will have a lifetime. Can hit several times.
Data from Hong Kong confirms this finding: in the Omicron epidemic in Hong Kong, the death risk of people over 60 years old is 252 times that of people under 30 years old.
It can be seen that in the face of the new crown virus, the risk of death of the elderly increases significantly, which is not conducive to “streaking”, which is why the average age of death of many new crown cases is over 70 years old.
Ratio of three doses of vaccination to no vaccination: 76 times
Among the risk factors for severe illness and death of COVID-19, advanced age and chronic underlying diseases A factor cannot be changed. So, can this part of the population only “run naked” in the face of the new crown virus?
More and more data show that the new crown vaccine, especially the third shot, can “arm” the vulnerable.
The latest data released by the Hong Kong Department of Health as of May 4 showed that the total mortality rate of the unvaccinated population was 3.04%, and the total mortality rate of the three-shot vaccine population was only 0.04%, a difference of 76%. times. This means that getting three doses of the new crown vaccine will greatly reduce the possibility of death after contracting the new crown virus.
Undoubtedly, the biggest gap in the data comes from the “ratio of old and young”. The death toll of young adults armed with three shots of the new crown vaccine has been firmly occupied by “0”, and the vaccine has not yet been completed. The number of deaths among those over 80 who were vaccinated was as high as 5,853.
The data from the mainland has also repeatedly confirmed the “armed ability” of the new crown vaccine. Among the critically ill and critically ill patients treated in a designated hospital in Jilin, about 85% have not completed the two-shot vaccination.
Only over 80 years old: 177 times
As mentioned earlier, in the latest data from Hong Kong, the elderly over 80 years old who have not completed the vaccination The death toll was as high as 5,853.
Thousands of people over the age of 80 have died from the new coronavirus. Has this situation turned around?
Wang Guiqiang, director of the Department of Infectious Diseases at Peking University First Hospital, told a reporter from Science and Technology Daily: “After receiving three doses of the new crown vaccine, the mortality rate of the elderly over 80 years old is very worthy of attention.”
Data show that after three doses of the new crown vaccine, the death toll of Hong Kong elderly people over 80 dropped sharply from thousands to 33, which is 1/177 of the death toll of people over 80 who have not completed the vaccination. Wang Guiqiang said that this fully proves the necessity of the third dose of the new crown vaccine for people over 80 years old.
“The data from Hong Kong shows that after the first, second, and third doses of the new crown vaccine for the elderly over 80 years old, the fatality rate of infection with Omicron will be gradually reduced, and the vaccine will never be vaccinated. The 16.48% of the vaccinated people dropped to 7.08% of the one-shot vaccination, 3.81% of the two-shot vaccination, and 1.2% of the three-shot vaccination.” Wang Guiqiang said, especially after the completion of the third vaccination, the fatality rate dropped to about 1%. Epidemic prevention and control is of great significance.
