2. Natural Immune Response:

The soreness is a natural response to the vaccine. The body recognizes the antigens in the vaccine as foreign and initiates an immune response to fight off the potential infection.

3. Injection Technique:

The injection technique can also influence arm pain. Proper administration of the vaccine into the muscle, rather than the subcutaneous tissue, minimizes pain and discomfort.

4. Individual Sensitivity:

Individual sensitivity to vaccines varies. Some people may experience more severe arm pain than others due to their immune system's response or underlying medical conditions.
