Do not let rumors interfere with the overall situation of the fight against the epidemic

Recently, the rumor of “pulmonary nodules after taking Kexin vaccine” has become a hot topic, causing a lot of anxiety among the public. A number of experts in the field have issued disinformation about such false information.

From the perspective of immunization principles, inactivated vaccines are not associated with the risk of lung nodules.

Pulmonary nodules have various causes, mainly divided into nodules caused by pathogenic infections such as viruses, bacteria, mycoplasma, and fungi, and non-infectious nodules such as pneumoconiosis and tumorigenic pulmonary nodules. Kexing New Crown vaccine is an inactivated vaccine, which is a very mature line of vaccine technology, and the virus has been “killed” during the preparation process to lose the ability to reproduce and infect, so it will not infect the lung tissue and produce nodules.

The vaccine is marketed in China under strict R&D and clinical trial procedures, and its safety is sufficiently guaranteed. The Kexing Xinguan vaccine has long passed the evaluation and approval of the State Drug Administration and the World Health Organization, and has been marketed and used in large quantities at home and abroad, and has accumulated many observations. The risk of pulmonary nodules has never been mentioned in vaccine-related adverse events.

The data from various places show that the increase in the detection of pulmonary nodules is related to the progress of domestic instruments.

Without vaccination, a significant percentage of the population will still detect pulmonary nodules each year. The detection rate of pulmonary nodules in the normal population varies from region to region, usually around 20% to 40%, and may reach 70% in high cases.

Pulmonary nodules are usually detected by CT of the chest. In China, CT machines (computed tomography scanners) used to be imported and expensive. In the past decade or so, the gradual rise of domestic brand CT has laid the foundation for the price reduction and popularity of CT machines. According to the statistics of relevant institutions, at the end of 2021, the national per capita CT ownership is about 34 units/million people, and the per capita CT ownership has reached 2/3 of the U.S. The increase in CT ownership has enabled more people to include CT examinations that were not available in the past in their medical checkups; and more and more hospitals have higher resolution CT machines, which can detect tiny lung nodules that were not visible before. The combination of these two factors has led to an increase in the number of people with lung nodules around us.

It is important to emphasize that pulmonary nodules are essentially just imaging shadows in the lungs and do not make a determination as to their nature. The vast majority of pulmonary nodules do not require treatment and only need to be reviewed regularly as prescribed by the doctor.

Currently, the neostriatal epidemic is still in its global pandemic phase, with the cumulative number of confirmed cases of neostriatal pneumonia worldwide having exceeded 610 million and cumulative deaths having exceeded 6.51 million. Although the efficiency of all types of Neoplasia vaccines at home and abroad has decreased due to the continuous mutation of Neoplasia strains, actual clinical data from both domestic and international locations show that Neoplasia vaccination can still significantly reduce the rate of severe illness and mortality in people infected with the virus, providing protection against the health of the population. Therefore, the vaccine remains an important tool in our fight against the epidemic, and people who are not contraindicated to vaccination should be encouraged to receive it voluntarily.

In this context, online platforms should take up the social responsibility of blocking rumors and strengthen monitoring and warning of inaccurate information, so as not to let rumors interfere with the overall situation of fighting the epidemic.
