Vaccines for People With Diabetes: What to Take
Infections are more dangerous for people with diabetes. High blood sugar weakens the immune system,
slows healing, and makes infections more likely to become severe. At the same time, infections raise
blood sugar, making diabetes harder to control. Vaccines are one of the simplest and safest ways to
break this cycle. Yet many adults with diabetes have never been told which vaccines they need.
Why Vaccines Matter in Diabetes
People with diabetes are more likely to be hospitalised with influenza, pneumonia, and some other
infections, and more likely to have complications. Vaccination reduces the risk of severe illness, hospital
stays, and complications such as heart attacks after infections. It also helps protect family members and
others around you.
Vaccines Commonly Advised for Adults With Diabetes
- Influenza: Every year, ideally before the flu season, since strains change.
- Pneumococcal: Protects against pneumonia and serious infections. Doctors choose the right
vaccine schedule for you. - Hepatitis B: Recommended for many adults with diabetes, especially those younger than 60, since
diabetes raises the risk of infection, including through shared glucose monitoring equipment. - COVID-19: As advised by current national guidance, particularly for higher-risk people.
- Tetanus and diphtheria (Td or Tdap): A booster every ten years, and after dirty wounds when
advised. - Shingles (herpes zoster): Often recommended for adults over 50, and may be considered earlier in
some high-risk adults. - Others: Depending on age, travel, and health, such as hepatitis A, typhoid, or RSV vaccines, as your
doctor advises.
Recommendations are updated from time to time, so ask your doctor for the current schedule in India.
When to Get Vaccinated
You can get most vaccines when your diabetes is stable, but do not delay them waiting for perfect
control. If you have a fever or acute illness, wait until you have recovered. Flu vaccines are best taken in
the months before the flu season, and in India, timing may vary by region. Many vaccines can be given
on the same day at different sites, as your doctor advises.
Are Vaccines Safe in Diabetes?
Yes. Vaccines used in adults are safe for people with diabetes. Side effects are usually mild, such as
soreness at the injection site, tiredness, or low-grade fever, and they settle in a day or two. Serious
reactions are very rare. The risk from the diseases is much higher than the risk from the vaccines.
Vaccines and Blood Sugar
Some people notice a temporary rise in blood sugar for a day or two after vaccination, as the body
responds to the vaccine, or if they feel unwell. Check your sugar more often after vaccination, drink
water, and continue your medicines. Call your doctor if your readings remain very high or if you have a
fever for more than a couple of days.
Protecting Yourself Beyond Vaccines
- Wash hands regularly, and avoid touching your face.
- Keep blood sugar in range, since this strengthens your defences.
- Treat cuts and skin problems early.
- Maintain dental and foot care.
- Avoid smoking, and limit alcohol.
- Follow sick-day rules, and call your doctor early when ill.
Keep a Vaccination Record
Maintain a record of vaccines with dates, in a notebook or phone. Carry it to medical visits and when
travelling. If you do not remember your vaccinations, your doctor can help decide what is needed.
Special Situations
Pregnant women with diabetes, people on steroids or immune-suppressing medicines, and people with
advanced kidney disease may need different schedules. Always tell the vaccinating doctor about your
conditions and medicines.

Frequently Asked Questions
Should every person with diabetes get a flu vaccine?
Yes, in general. Yearly flu vaccination is advised for adults with diabetes, unless there is a medical
reason to avoid it.
Can vaccines raise my blood sugar?
Sometimes slightly and briefly. Monitor your sugar for a day or two, drink water, and contact your doctor
if it stays very high.
Is the pneumonia vaccine necessary if I am healthy?
Diabetes increases the risk of serious pneumococcal infection, so doctors commonly advise it even if
you feel well.
Can I take vaccines if my sugar is high?
Usually yes. Do not postpone vaccines for perfect control, but wait if you are acutely ill.
