In case you aren't aware of the concept of the Original Antigenic Sin, it's based on evidence how the immune system shapes based on the first childhood infections and that this dominates our lifelong immunity. So there isn't really a scientific consensus yet if this is something positive or negative to our immunity because there isn't really a human control to check if people without any infections turn out with "better" immune systems.
In general, I don't like the generalization of the immune system into "strong" and "weak" at all. While we might be equipped better for one pathogen, we might become more susceptible to another.
Regardless, this poll isn't about any infections, but about typical severe early childhood infections for which vaccines are often available.
I know that this is difficult to answer because it's usually our parents who would need to be aware of it at the time and tell us later. Unless you remember, of course.
