Morphology
The meaning 'a substance or organism that stimulates an immune response' is directly and transparently derivable from 'immunize' (to make resistant to disease) combined with 'agent' (a thing that causes an effect). The attributive participial construction 'immunizing agent' literally signals 'an agent that immunizes,' a common compositional pattern cross-linguistically, so a B1 learner who knows both constituents should understand it.
Etymology
Immunizing agent is a phrase that shows a simple picture: immunizing means 'teaching' the body's defenders and agent means a thing that does the job. So, an immunizing agent is something put into the body to train it to fight disease and give it 'immunity'.
