9/25/2021

This article explores the mechanisms behind the side effects experienced after receiving a vaccine, specifically focusing on the soreness in the arm commonly associated with vaccination. It explains that the immune response triggered by vaccines involves the activation of white blood cells and the release of cytokines, which can lead to inflammation and pain at the injection site. The article discusses how the vaccine formulation and the body's immune reaction contribute to the intensity and duration of these side effects. It also emphasizes that these side effects are generally mild and temporary, indicating that the immune system is responding appropriately to the vaccine.
