Can vaccines cause fever?

I just got my annual flu shot, and now I'm feeling a bit feverish and achy. My friends told me it's normal to feel unwell after a vaccine. So, can vaccines commonly cause a mild fever as a side effect?

Yes, a mild fever after vaccination is quite common and actually shows your body is building immunity. My mother always tells us to drink warm kanji and rest, but we must trust the doctor's prescription. They usually give a simple paracetamol to manage the temperature.

Haan na, vaccine ke baad thoda fever aana toh normal hai, almost everyone gets it. It just means the vaccine is doing its work inside. Bas take a paracetamol if your doctor suggested it and rest for a day.

Oh absolutely, I got a mild fever after my last booster shot and used it as the perfect excuse to lie in bed and order hot, comforting khichdi and labra. It usually lasts just a day or two, so don't worry, just keep some light snacks ready!

Yes, vaccines can cause a temporary fever as the immune system responds. If you have diabetes, a fever might cause a slight rise in your blood sugar levels, so keep monitoring your glucose. Avoid sweet electrolyte drinks, stick to plain water, and follow your doctor's advice.

I am planning to get my routine shots next week but I am a bit scared of getting a high fever. Does the fever usually start on the same day, and how long does it typically last? Any gentle advice on how to prepare would be really helpful.
