Uh, that was what you posted. I guess you’re “just asking questions,” right? Never mind the huge amount of evidence that vaccines don’t cause diabetes.
Do Vaccines Cause Autoimmune Diseases?
Associations between vaccines and autoimmunity are another frequently cited safety concern and have been heavily studied in relation to a number of different autoimmune (AI) disorders including diabetes mellitus type 1 (DM type 1), Guillain Barré Syndrome (GBS), multiple sclerosis (MS) and other demyelinating disorders. Existing epidemiologic studies have found no associations between the number of different vaccines and an increased risk of autoimmune disorders. Two recent systematic reviews looking at the association between different individual vaccines and central demyelinating disorders (hepatitis B, human papilloma virus (HPV), influenza, MMR, varicella, tetanus, Bacillus Calmette Guérin (BCG), polio or diphtheria) concluded that there was no relationship between receipt of a vaccine and development of MS (
Mailand and Frederiksen, 2017;
Mouchet et al., 2018). Links with DM type 1 have also been extensively studied. A German study which included more than 1900 children from a prospective cohort data set found no association between vaccination and development of DM type 1 in children with a high familial risk of AI disorders (
Beyerlein et al., 2017). A metanalysis of 23 different case control studies including 11 different vaccines and 13,000 patients found no association between vaccination and risk of DM type 1 (
Morgan et al., 2016).
The relationship between vaccines and diabetes has been the subject of several excellent studies.
The hypothesis that the timing of vaccines either causes or prevents diabetes was tested in 21,421 children who received the
Haemophilus influenzaetype b (Hib) conjugate vaccine between 1988 and 1990 in the United States. These children were followed for 10 years after receiving the Hib vaccine. The risk of diabetes was indistinguishable from a group of 22,557 children who did not receive the Hib vaccine.
Another excellent study evaluating the relationship between vaccines and diabetes was performed using data from the Vaccine Safety DataLink. Four large health management organizations (HMOs) were used to identify children with diabetes born between 1988 and 1997. All four HMOs maintained registries of children with diabetes and cases were confirmed by means of medical records. Investigators compared 252 cases of diabetes with 768 matched controls. Children who received whole-cell
pertussis,
MMR,
Hib,
hepatitis B or
varicella vaccines were not at greater risk for diabetes than children who did not receive those vaccines. In accord with the Vaccine Safety DataLink study, several other well-controlled retrospective studies found that immunizations were not associated with an increased risk of developing diabetes.
In 2011 the Institute of Medicine reviewed studies of adverse events related to vaccines. One of the associations studied was whether the tetanus component of the DTaP vaccine caused type 1 diabetes. The committee concluded that development of type 1 diabetes was not caused by receipt of this vaccine. In another study, investigators followed individuals born in 1974 for 20 years who had or had not received the BCG vaccine and found that receipt of vaccine did not increase the risk of diabetes.
Other studies listed below show that children who received the rotavirus, polio, or HPV vaccines were not at greater risk of developing diabetes. In addition, women inoculated with the influenza vaccine during pregnancy were not at increased risk of gestational diabetes.
Therefore, the best available evidence does not support the hypothesis that vaccines cause diabetes.
A multi-institution epidemiological study found no evidence that the
routine childhood immunization schedule is associated with the development of type 1 diabetes.
Researchers at eight integrated health care organizations in California, Colorado, Minnesota, Oregon, Washington and Wisconsin examined associations between three measures of the childhood immunization schedule and the incidence of type 1 diabetes in children aged 2 to 14 years.
“One of the concerns that some parents have is the safety of the overall schedule, meaning there is some sort of risk to their child [getting] all of the vaccines as recommended, according to the schedule,” Glanz told Healio. “One of the specific concerns that parents might have is [a fear of] receiving too many vaccines at once might overwhelm their immune system.”
A previous report concluded that available data suggested the schedule was safe but that more research was needed, Glanz said.
“That was sort of the impetus behind this study, to look at the safety of the overall schedule, rather than individual vaccines,” Glanz said. “We chose diabetes because it's an autoimmune disease, and some parents have
concerns about vaccines causing autoimmune diseases.”
Using a cohort of 584,171 children from the eight health systems, the researchers examined cumulative antigen exposure in the “first few years of life,” Glanz said, cumulative aluminum exposure through the first 14 months of life and whether either factor increased the risk for diabetes.
The study found that the average number of days unvaccinated and cumulative antigen exposure were not associated with type 1 diabetes. Cumulative vaccine aluminum exposure was associated with a reduced incidence of type 1 diabetes (adjusted HR = 0.89; 95% CI, 0.81-0.97).
“In this study, we didn't see any evidence that getting your vaccines on time increases the risk for an autoimmune disease like diabetes,” Glanz said. “That is something that pediatricians could theoretically use in conversation” with patients about the safety of vaccines.
