I just wonder why people are comparing the side-effects of others. it's a completely useless exercise. Each of us are different.
Nearly 50% of the people do NOT experience any significant side effects but after a while they do develop very good immunity. Some do experience a mild pain or fever symptoms as our innate immune system kicks in.
In the US (Moderna & Pfizer) the side effects were mostly from women. (about 79%). So there seems to be a gender bias - possibly testosterone plays a part.
It's unclear why some people react, but it's due to several factors, including age, health, environment, nutrition, and gender. Generally the young tend to react quickly, as we get older the immune system takes it's own time to jump into action.
With a vaccine you develop immunity. If you are infected with the virus then things can be different. If you refer to my older posts, I have written the reasons for it - as the explanation was offered by Prof Shiv Pillai of Harvard Medicine.
