Introduction: Vaccination is one of the main means of preventing influenza and reducing harm to the population. However, it should be noted that the COVID-19 epidemic may have influenced the drop in influenza vaccination coverage. Objective: This study aims to conduct a cross-sectional study on influenza vaccination in Brazil in 2022, characterizing by category, age group and clinical risk category by pathology. Material and Methods: The work was carried out in the form of a descriptive study with analysis of data obtained from the National Immunization Program Information System - SIPNI, Ministry of Health, Health Surveillance Secretariat and Executive Secretariat in the year 2022. Results: As shown in the results of this article, the total amount of influenza vaccines administered in 2022 was 62,918,552 million doses (80.72% of the vaccinated population), which is well below the 95% target set by the Ministry of Health and the World Health Organization. Final considerations: The good indicators of the past must be resumed, thus avoiding the return of infectious diseases that were once eradicated, or in the case of influenza, an increase in the number of deaths resulting from the disease.
