Morphology
The phrase is a straightforward compositional combination: 'acquired' (obtained) qualifies 'immunity' (biological resistance), so the meaning 'immunity obtained after exposure or vaccination' is directly derivable from the parts. This is a common, cross-linguistic medical/biological pattern (e.g., Spanish 'inmunidad adquirida'), so a B1 learner who knows both words will readily understand it.
Etymology
Acquired immunity shows a simple idea: acquired means 'to get' and immunity means 'protection from a disease'. So acquired immunity is the protection you 'get' after you catch an illness, have a vaccine, or receive it from your mother, not protection you are born with.
