Objective: To identify the knowledge and compliance with the technical recommendations of the Brazilian National Immunization Program regarding immunobiological preservation. Methods: A cross-sectionaldescriptive study was conducted among 21 registered nurses and 49 licensed practical nurses from twenty-six primary health care units in a municipal district in the State of Minas Gerais, Brazil. Results: Several deficiencies that can affect the effectiveness of the recommendations of the National Immunization Program were identified: inadequate management of temperature of the refrigerator, lack of knowledge of the technical procedure for biweekly cleaning of the refrigerator, and lack of awareness of the recyclable ice box. In addition, there was a lack of knowledge of vaccines that would continue active even though they had been frozen. Conclusion: There is need for education and training of professionals responsible for the immunobiological preservation.
