The more immunity we have, the better we are!

But while immunity protects our bodies, immunity can also cause illness.

We can get illness due to immunity?What do you mean?

Occasionally, immune cell abnormalities or some other factor can hurt ourselves, the immune cells that are supposed to protect us. Allergic reactions and autoimmune diseases are examples of this. The whole truth of it is not yet clear, but these are common illnesses even for young people like you.

But how was such a complicated system find?

In the old days, science and technology were not so developed, so it seems that they were empirically aware of the existence of immunity.

Empirical?

It has been thought that the fact that once infected with an illness does not worsen the illness the next time, is rooted in humans. Over 2000 years ago, several immune properties were used therapeutically as a curse-like remedy.

I was surprised that it was empirical at first.

I'm excited that it's still connected to the present day.
