A Survey on Side Effects of COVID Vaccine on Human Body

The COVID-19 Vaccine when injected in our body produces Antibody (due to reaction between L- Histidine and DNA molecule of our Body) has side-effects like, fever, body pain, etc. It?s due to Bond formation (Temporary) between COVID Vaccine and Blood Component (Iron). This forms a Temporary Complex Compound which results in side effects. But as this bond is temporary it?s eventually broken down by Body?s Immune System or Medicines taken for Relief and in course of time due to this function our body builds resistance to the virus.
