This is helpful, and makes it sound like genetics have the greatest impact on the effectiveness of an immune system in context…

As a geneticist with a little (very little) background in immunology I’m going to say, idk, maybe? Maybe not. Genes always matter, so sure. But there’s a pretty big stochastic factor with the immune system, a whole lot of environmental factors, and a ton we don’t understand. Starting with the definition of “strong immune system” - and if you can’t define that you can’t answer (or meaningfully ask) the question.

There's also the factor of initial viral load.

Jack gets covid, has no symptoms, and only notices because his work did a random screen.

Jane gets covid and dies from lung failure.

Maybe Jack got a single viral particle and his body had plenty of time to ramp up is response but Jane got coughed on by someone chock full o virus and by the time she started producing antibodies her lungs were already saturated.
