What happens if you get hepatitis b vaccine twice?

My child had his Hepatitis B vaccine, but I'm worried if by mistake he gets another dose too soon. What happens if you get the Hepatitis B vaccine twice, or more than required?

Nothing dangerous will happen if you get the vaccine series twice. Your body will just produce more antibodies, though you might get a slightly sore arm again.

Your immune system is super strong and can easily handle an extra vaccine series. Just eat healthy, keep up your daily workouts, stay hydrated to flush out any mild sluggishness, and you'll be absolutely fine.

I had to take the whole series again for my college admission because I couldn't find my old yellow card. Absolutely nothing happened, just a mild fever for one day which is super normal after any vaccine.

In our times, records were often lost and many of us took duplicate vaccines when joining new jobs. It is completely safe and only strengthens your immunity against the virus, so please keep your mind at ease.

Haan, don't worry, tension mat lo! It's actually quite common if someone loses their childhood vaccination records and takes it again as an adult. Extra dose se koi n नुकसान nahi hota, body handles it easily.
