The objective of this qualitative study was to understand the nurse's perception of the supervision of vaccination activities carried out in Primary Care Centers. The vaccination rooms selected for this study were from a preliminary quantitative study which analyzed the best vaccination rooms in the macroregion of western Minas Gerais, Brazil, in which 12 rooms met 100% of the structural criteria. The nurses responsible for these rooms were interviewed and the data obtained was analyzed through thematic content analysis. The results show the lack of a supervision process by nurses, which might have occurred due to the quantity of actions under their responsibility. The nurses need a proactive attitude with educational actions and more effective monitoring of vaccination room activities, avoiding the occurrence of flaws in the procedures which might influence the quality of the immunobiological preparation made available for the population.
