Why Get Vaccinated?

Doctor discussing with her female patient on the possible options

When you have diabetes you are more prone to infection due to an abnormal immune system. As the body’s defence system is not functioning well, persons with diabetes have a higher risk of getting serious problems or even die from a simple infection such as flu or pneumonia.

Vaccinations are safe and can prevent or reduce the severity of flu or pneumonia. The side effects are mild and usually go away quickly.

What is the Next Step?

See your doctor before you get a vaccination. Your doctor will check to make sure your vaccinations are up to date.

There are people who should not get vaccinated, such as those with a serious allergic reaction to a vaccine or any ingredient in the vaccine. Others may have diseases or take medications that weaken their immune system.

When you next see your doctor, ask about vaccinations. It’s the best way to protect yourself against infections.
