Impact of COVID-19 Vaccines on Type 2 Diabetes: Insights and Explanations
News Article: COVID-19 Vaccination and Type 2 Diabetes
People with type 2 diabetes (T2D) are at a higher risk of experiencing severe complications from COVID-19 compared to the general population. This increased risk is due to factors such as an impaired immune response linked to fluctuating blood sugars and coexisting conditions like heart disease or obesity.
Regarding COVID-19 vaccination, people with T2D may experience mild side effects similar to the general population. While some research suggests a higher risk of side effects, other studies do not confirm this difference. However, vaccination is strongly recommended for people with diabetes because their risk of serious COVID-19 complications is greater, and vaccination helps reduce that risk.
People with T2D who receive the vaccine may notice higher blood sugars for a few days after vaccination. This is due to the blood sugar rising in response to the mild, temporary inflammation that the vaccine triggers. Individuals experiencing this should contact a doctor if they have concerns.
Individuals who are immunocompromised or have poorly controlled diabetes should consult a doctor to determine which COVID-19 vaccine is best for them and whether they need additional boosters. People with T2D need to consult a doctor or healthcare professional to determine if they need additional COVID-19 vaccine boosters.
It is important to note that there is no information suggesting that insulin or other diabetes medications affect the effectiveness of vaccines. The Novavax protein subunit vaccine, approved for individuals 12 years and older, uses a part of a virus to create the vaccine and cannot cause the disease.
In the United States and parts of Europe, Moderna and BioNTech-Pfizer mRNA vaccines are in use in 2025. A healthcare professional will administer the Novavax vaccine as jabs (shots) in the upper arm. The Novavax protein subunit vaccine was authorized in 2023.
If someone with T2D believes they have COVID-19 symptoms, they should call a doctor and provide their glucose reading, ketone reading, fluid consumption details, and a description of symptoms. In rare cases, serious side effects such as swelling of the tongue or hives may occur, and these require immediate medical attention, including an injection of epinephrine.
The CDC's 2024 to 2025 vaccination schedule for COVID-19 vaccines is subject to change, and individuals should confirm their vaccination schedule with a healthcare professional who administers the COVID-19 vaccination.
New therapies such as dapagliflozin have been shown to be safe during acute COVID-19 infection in patients with or without T2D, suggesting possible therapeutic safety in this group.
In conclusion, COVID-19 vaccination is safe for individuals with T2D, with side effects comparable to those without diabetes, and vaccination is important given the higher risk of severe COVID-19 in this group. New therapies like dapagliflozin may also provide additional safety during COVID-19 illness in T2D patients.
