Does the immune system ever crush an infection it wasn’t ready for?

Say you got some pathogen inside you, and it’s starting to replicate and your immune system isn’t prepped with the antibodies. Does it ever happen then that infection still gets nowhere because of reasons other than you consciously recognizing that you were exposed and taking some meds early on?

Yes of course.

Remember early COVID-19? There were loads of people who got infected without having any symptoms, especially young people.

Everyones immune system is different based on genetics, age, and pathogens you encountered in the past, so that your standard response can completely be enough to handle a new pathogen.

Also amount of exposure matters a lot. If you get lots of pathogens they basically have a head start over your immune system, while when you only get very few then your immune system can have antibodies ready long before the pathogens had a chance to multiply out of control
