Since early 2021, the Beta Cell Foundation has collected data on vaccine adverse events from 528 patients with type 1 diabetes by using an online database for analysis.
The analysis showed that some patients with type 1 diabetes experienced elevated (or disturbed) blood glucose levels after vaccination with COVID vaccines:
- After receiving the first dose of an mRNA vaccine (Moderna or Pfizer COVID vaccines), approximately 10 percent to 15 percent of the patients reported an increase in blood glucose within 1 to 2 days and 2 percent reported a decrease;
- After receiving the second dose of an mRNA vaccine, approximately 30 percent reported an increase in blood glucose, and 1 percent reported a decrease.
- After the second dose of the Johnson & Johnson (Janssen) vaccine, 42 percent had elevated blood glucose.
What is the link between type 1 diabetes, COVID, and the vaccines?
Statistical Analysis of Vaccine Adverse Diabetes Events
Late at night on May 31, 2022, hundreds of parents from 26 provinces and central government directly controlled municipalities across China sent out an online plea for help: more than 600 children had developed type 1 diabetes after receiving the Chinese-manufactured vaccines. Some parents said that their families had no history of diabetes for three generations. Is there a correlation between the vaccines and these childhood diabetes cases?
In addition, we have received a report of adverse diabetes events after vaccination in mainland China, and the 211 cases in the report had quite detailed information. We analyzed the association between these 211 cases of diabetes and the vaccines received by the patients, by using the same principles as in our previous analysis of the over 800 leukemia cases, with a conservative approach.
- Gender and age analyses
The patients in these adverse events were predominantly male, with a median age of 12 years old. This is very similar to the age of prevalence of type 1 diabetes, which is more prevalent in children aged 10 to 14.
