[NTD News October 16, 2021 Beijing time]After the advent of the new crown vaccine, it is considered to be the solution to the epidemic. Many governments have vigorously promoted vaccination to fight for the coverage of the vaccine. However, the latest study published in the European Journal of Epidemiology found that the rise and fall of the epidemic is not directly related to the vaccination rate. The researchers called for reexamination of vaccination prevention measures. Infectious disease experts believe that to fight the virus, human beings should also find ways to prevent the epidemic from themselves.
Research: The vaccination rate has no obvious relationship with the trend of the epidemic
With the outbreak of epidemics in various countries around the world, the surge of new crown cases is often thought to be related to people who have not been vaccinated. However, scholars from Harvard University and Pennsylvania State University in the United States have studied the new crown epidemic in 68 countries and found that there is “no obvious relationship” between the percentage of the vaccinated population and the new cases.
In these 68 countries, regardless of whether the vaccination rate is high or low, the epidemic situation has soared. The study puts Israel as an example. Although more than 60% of the population in Israel has been fully vaccinated, the number of confirmed cases per 1 million people is the highest.

Dr. Lin Xiaoxu, former director of the U.S. Army Research Institute’s Department of Virology, explained that if vaccination is very effective in controlling the epidemic, then in the scatter diagram based on the data of each country, it should be seen that most countries are increasing with the vaccination rate. , The number of confirmed cases decreases, and the straight line should show a downward trend from high to the left and low to the right. “But the data of 68 countries are put together to analyze, there is no such rule, and to a certain extent there is a reverse trend.” He said.
The study also analyzed the number of confirmed cases and vaccination rates in 2947 counties in the United States for two weeks, and did not see the changes that people wanted: the more people vaccinated, the lower the number of confirmed cases.
In contrast, among the top five counties with the highest percentage of fully vaccinated populations (84.3% to 99.9%), four of them are classified as “highly transmitted” counties by the Centers for Disease Control and Prevention (CDC).
Of the 57 counties classified as “low transmission” by the CDC, 26% of counties have a fully vaccinated population of less than 20%.
This peer-reviewed study, officially published in the European Journal of Epidemiology in September, mentions 4 main points at the end of the article:
1. It is necessary to re-examine the use of vaccines as the only reliance on epidemic prevention. Especially considering the Delta variant and the possibility of other variants in the future.
2. When increasing the vaccination rate, other drugs and non-drug prevention methods need to be considered. For example, maintain a socially safe distance, wash hands frequently, etc.
3. Although vaccination can prevent severe illness and death, the US CDC report pointed out that from January to May this year, the hospitalization rate of fully vaccinated patients increased from 1% to 9%, and the mortality rate increased from 0% to 15.1%.
4. The practice of stigmatizing people who have not been vaccinated does more harm than good.
Lin Xiaoxu pointed out that the CDC figures show that the burden of the variant viruses on the local epidemic exceeds the efforts to promote vaccination, because these variant viruses also have a certain degree of immune escape ability. He believes that this study points out a clear problem. There are other factors that will affect the development of the epidemic.
Epidemic prevention cannot rely solely on vaccine experts: finding internal causes and changing oneself are fundamental
If vaccines are not the main cause, what other factors will affect the trend of the epidemic?
The world‘s fifth wave of epidemics that began in mid-to-late June, after three months, finally declined in mid-September. Dong Yuhong, a European virology and infectious disease expert and chief scientist of a biotechnology company, pointed out that since the beginning of the pandemic, the five waves of epidemics that have appeared around the world seem to have a pattern: from the beginning of each wave to the peak and the turning point. After about 3 months.
This phenomenon does not seem to have changed much due to the global mass vaccination. So whether the ups and downs of the epidemic is not entirely limited by the measures people take to administer vaccines, but is related to some characteristics of the new coronavirus itself, Dong Yuhong said, this requires further research by scientists.
In addition, the protection provided by vaccines is only part of the epidemic prevention, and each person’s own health and immunity are also very important. When a person’s own immunity is strong, it can reduce the probability of infection, and even reduce the risk of severe illness.
For example, human epithelial cells are one of the natural immune barriers. They can secrete interferon, an important substance that interferes with virus replication. The University of Louisville in the United States published a study in the scientific journal Nature, and pointed out that the more interferon secreted in the early stage of the disease in patients with the new crown, the milder the disease. This represents a higher level of interferon, which can reduce the incidence of severe COVID-19.
Dong Yuhong said that in addition to studying the impact of external factors such as vaccines on the epidemic, it is necessary to find out the internal factors that cause the human body to be easily infected. For example, check whether you have problems with uneven nutritional intake, smoking and drinking, disturbance of work and rest, emotional and mental problems. These will damage the body’s immunity.
At the same time, we must also pay attention to our own energy state. Dong Yuhong explained that the energy mentioned here is not an abstract concept. Modern biomedicine can measure the energy of living beings. For example, the energy at the cellular level is ATP. The human heart needs energy to beat, speak, and do things. Strong physical strength, good mental state, and good self-emotion control are all signs of ample energy, and this type of person has better resistance.
On the contrary, diseases caused by viruses will deplete the body’s energy. The long-term symptoms of the new crown (new crown sequelae) announced by the World Health Organization (WHO) include fatigue and depression deep in the bone marrow. These symptoms are manifestations of a lack of energy in the body. For example, Dong Yuhong, a patient with long-term symptoms of new coronary disease has made breakfast and has no energy to eat because his energy level is already very low.
Dong Yuhong believes that epidemic prevention should not only rely on vaccines, but also self-protection. At the same time, we should start with how to enhance our own immunity and energy level in order to fundamentally stay away from the new coronavirus and reduce the virus’s harm to the body.
In a chaotic world, if you have a healthy way, look at health 1+1!
