Morphology
The phrase is directly compositional: 'hypersensitivity' means an excessive response and 'reaction' means a bodily/physiological response, so together they denote an excessive bodily response to an allergen. Although it is a medical term with varying severity, its meaning is transparently derivable from the constituent words and similar constructions exist across languages.
Etymology
Hypersensitivity reaction comes from the idea that the body's defense is hyper, meaning 'too much', and sensitivity, meaning 'easily affected', so it reacts strongly to harmless things like pollen or some foods. That's why a hypersensitivity reaction means a 'too strong or wrong reaction' by the body, causing sneezing, rashes, swelling, or in serious cases, shock.
