The objective of this article is to analyze the process of formation of Afectadas México Vacuna Virus del Papiloma Humano, a group of mothers organized from the health affectations of their daughters attributed to the immunization against this virus, as a space of collective care. The qualitative research, with in-depth interviews and an analysis from the sociocultural perspective of emotions and crossed by gender, has focused on reflecting on the causes that have led these mothers, as primary caregivers in the process of care and attention to the health of the affected daughters, to build alternative spaces of visibility, mutual support, dialogue and collective denunciation, taking as main tool the use of social networks and digitality, as these are the most used means of mass contact at present, with projection to different social spheres. From this study it has been concluded that the competent contexts to the health-disease-care process are not alien to social responses that take shape in organizations of denunciation, rejection and protest, even from a non-physical and conventional mobilization. The post-vaccine effect has served to make it clear that health is also a matter of social and political competition, in which emotions are the binding element that strengthens the union. The experience with the loss of the daughters' health links the expressions of feeling in action, interaction and politicization of women from their own material and ideological resources.
