What immunologically is going on to make people asymptomatic carriers of COVID-19?

What mechanism immunologically speaking, causes people to be asymptomatic COVID-19 carriers? Is it that the innate immune system is more capable of controlling the infection very early in certain individuals? 

I've asked my immunology professor and a few other medical professionals and they have all stated that it is not yet clear. I was curious if anyone has a better answer for me :) Thanks!

It's not really accurate to say people are "carriers" of COVID, implying some kind of long term equilibrium state.  The human immune system will always fight covid and the battle will be won or lost.

The spectrum of symptoms will be determined by a lot of factors.  Some may have had previous exposure to a similar virus.  Some people will just not recognize the symptoms on top of their normal bronchitis, etc.
