Question: Why some people has a weak immune system and some don't?

Hi Sofia,

I think the reason really comes down to individual differences in the sense that we get immune antibodies from our mums at first, then also as we go through life we come in contact and develope our immune systems in different ways, by vaccination, and by getting ill and fighting the infection. Also, our immune systems can be influenced by underlying conditions. So someone who has diabetes (which is becoming more and more common these days) is due to that disease more susceptible to getting sick from other things, like a Staph infection etc…

Hope that makes sense! Thanks for the great question.
