In some parts of the world, the cold season has already come, and, it is known that winter is a good home for the viruses. No matter how hard we try to immunize our children against colds or other severe illnesses, it is not sufficient, because there is a continuous forthcoming of new viruses that pull down their bodies. I often heard some voices saying: "Her immunity is not good enough". I think it has nothing to do with this, since the body is not prepared for new viruses, and it's impossible to stay strong against new illnesses. I mean, it's a matter of luck. Very few people are immune against new viruses, never mind a child. So, I don't know if immunity means to be invincible against the illnesses, but for sure it helps our children to go through affections easier.
