As everyone knows, vaccines are the most effective weapon against virus infection and disease transmission. As the new crown vaccine is being hot around the world, it has been proved to be effective in preventing COVID-19 infection. With the development of public health, free vaccination has been carried out in the first category of vaccines in recent years, so that diseases such as smallpox, chickenpox and measles disappeared in the old society. Meanwhile, viral infections such as influenza and hepatitis were also greatly reduced.


But recently, some netizens suggested that some colleagues discovered the type 1 diabetes after vaccination, which is suspected to be caused by the vaccine. What is the truth? And the analysis is as follows.


Correlation between vaccine and type 1 diabetes mellitus

According to the literature, early studies have found that certain vaccines may increase the risk of type 1 diabetes. For example, in the mid 1980s, a case control study conducted in Sweden showed that vaccination against tuberculosis, smallpox, tetanus, pertussis or rubella did not increase the risk of diabetes. However, if certain vaccines, such as Haemophilus influenzae type B vaccine, inoculate more than 2 month old, the risk of type 1 diabetes may increase.


But another 10 year follow-up study conducted in Finland on a clinical trial of more than 100 thousand children with Haemophilus influenzae type B did not confirm its association with type 1 diabetes, and subsequent studies did not support the association between regular childhood vaccination and increased risk of type 1 diabetes. So far, at least, neither adults nor children have found that vaccination increases the risk of type 1 diabetes.

Is it a vaccine that causes type 1 diabetes after vaccination?

From the above literature, the answer is negative, but some people still doubt whether it is the antibody produced by the vaccine attacking islet cells and causing islet cell failure to cause type 1 diabetes.


Now we are going to analyze the characteristics of type 1 diabetes. Type 1 diabetes, also known as insulin-dependent diabetes mellitus, is caused by the absolute lack of insulin in the failure of islet cell function. Its pathogenesis is mainly due to autoimmune defects and heredity. These factors are mostly congenital, so type 1 diabetes also occurs in adolescents and children. However, a small number of patients belong to late onset type 1 diabetes in adults.


So what the netizens say is that type 1 diabetes is found after vaccination. It may belong to type 1 diabetes of late onset in adults. In fact, we are not unfamiliar with similar statements. Many rumors say that vaccines lead to such problems. In fact, it is a coincidence of time points that leads to “vaccine back to the pot”.


In addition, from the data of vaccination, our vaccination population is calculated in billions, and every person from small to large will have dozens or even dozens of different vaccines. If the antibodies produced by the vaccine really attack the pancreatic islet cells and cause type 1 diabetes, then the incidence rate of type 1 diabetes in China will certainly not be low. Incidence rate incidence rate of type 1 diabetes mellitus in China is only 1.01/10 million, and it is still one of the lowest in the world with the lowest incidence of type 1 diabetes. The theory that the antibody produced by suspected vaccines attacks islet cells is not established, according to the results of the 2010-2013 year coverage of the 1 type diabetes research in all 13 regions in 505 hospitals nationwide.


In summary

So far, there is no correlation between the vaccine and the incidence of type 1 diabetes. We should not be able to detect type 1 diabetes as a result of individual vaccination. It is said that the vaccine will lead to type 1 diabetes. Vaccines do have side effects, but most of them are lighter. Taking COVID-19 vaccine as an example, from the perspective of large-scale vaccination experience in China, the side effects may be very mild after vaccination, and most of them can recover by themselves. Therefore, it is not necessary for the suitable population to fight against vaccines because of their side effects.
