Previous studies have shown that physical attractiveness is one of important aspects in mate choice. Facial traits perceived as attractive may be linked to potential mate quality, or more precisely to their reproductive potential, health and ability to invest in his mate and offspring. Mating with individuals with more reactive immune system could lead to higher reproductive success and thus it is possible that visual cues facilitating detection of such traits may have evolved. The main aim of the present thesis was to test a possible association between the reactivity of the immune system response to foreign antigens (stimulated by vaccination) and facial attractiveness perceived by opposite sex individuals. Further, we investigated visual changes occurring during immune system activation. We did not find any association between measures of reactivity of immune system and perceived facial attractiveness. However, participants with activated immune system were rated as significantly less attractive and were significantly paler. Overall, our results suggest that people are sensitive to visual cues to current health status but not to overall quality of the individual.
