(Fighting against New Coronary Pneumonia) China's State Council Joint Prevention and Control Mechanism: Inoculation of New Coronary Vaccine Will Not Cause Leukemia and Diabetes

  China News Service, Beijing, July 23 (Reporter Li Chun) In response to the rumors that the vaccination of the new crown vaccine caused leukemia and diabetes, Wang Fusheng, an academician of the Chinese Academy of Sciences and director of the Department of Infectious Diseases of the Fifth Medical Center of the PLA General Hospital, attended the Joint Prevention and Control Mechanism of the State Council on the 23rd. The press conference retorted that vaccination of the new crown vaccine will not cause the occurrence of leukemia and diabetes, nor will it affect human genetic development, cause tumor metastasis and spread, and cause antibody-dependent enhancement (ADE) as some online information says. It's all irresponsible and wrong speech on the Internet.

  Wang Fusheng analyzed at the meeting and pointed out that, first of all, the various substances in the vaccine are safe for the human body and will not cause disease directly.

Inactivated vaccines mainly contain microgram-level viral antigens or recombinant proteins, as well as other components such as aluminum hydroxide adjuvants and excipients.

Their content in vaccines is in compliance with relevant regulations and cannot themselves cause disease.

For the reagents used in the vaccine production process, they have all passed the strict inspection of relevant institutions and reached the standard. For example, the residual formaldehyde content in the currently inoculated inactivated vaccine is within the range of ≤0.027μg/dose, and its concentration is higher than that in human blood. The steady state formaldehyde level (2.6 mg/L) was also 47 times lower.

  Second, the inactivated vaccine against COVID-19, which has the largest number of vaccinations in China, has sufficient security and has been recognized by international organizations.

The production and inactivation process of hepatitis A vaccine, rabies vaccine, and polio vaccine that have been marketed at home and abroad and have been used for decades is basically the same. So far, there is no report that vaccination of these vaccines is related to the occurrence of leukemia or diabetes.

After the outbreak of the new crown virus, a number of new coronavirus vaccines developed in China have been included in the World Health Organization's emergency use list and have been used in more than 100 countries, achieving the expected results and meeting international standards for safety.

  Third, clinical monitoring and statistical data show that in the four years before and after the outbreak of the new crown epidemic, the number of visits and hospitalizations for diabetes and leukemia were basically the same, and there was no significant change, indicating that vaccination with the new crown vaccine will not cause the occurrence of leukemia and diabetes.

For example, in 2018 and 2019 before the outbreak of COVID-19, the proportion of hospitalizations due to leukemia in China was 0.15% and 0.14%, respectively, while in 2020 and 2021 after the outbreak, the proportion of hospitalizations was 0.13%.

In 2018 and 2019, the number of hospitalizations for diabetes accounted for 2.1%; in 2020 and 2021 after the outbreak, the number of hospitalizations accounted for 2.2%.

  Wang Fusheng said that according to China's epidemic prevention and control policy, China began to conduct large-scale vaccination of the new crown vaccine last year.

At present, the vaccination rate of 3-12-year-old children and 12-17-year-old adolescents in China is 90%-100%, and the total number is nearly 250 million.

In the context of large-scale new crown vaccination, it is an inevitable phenomenon that a large number of vaccinations coincide in time with the natural occurrence of certain serious diseases.

  "Everyone can simply calculate that if the new crown vaccine will really cause diabetes and leukemia, then the number of medical visits and hospitalizations will increase significantly, but from the actual monitoring and clinical statistics, we have not seen it. This phenomenon." Wang Fusheng said that based on the above analysis, it is safe to say that the new crown vaccination will not cause leukemia and diabetes.
