Unilateral axillary lymphadenopathy following COVID-19 vaccination

Abstract

Objectives: COVID-19 vaccine effects on the lymph nodes of the axillary lymph nodes were examined in this study by comparing the characteristics of the nodes before and after immunisation. Methods: More than twenty-five employees who took part in the company's immunisation campaign were considered for employment. Before vaccination, one week after the first dose, and one week after the second dose, the ipsilateral vaccinated arm was examined by axillary ultrasonography. The total number of visible nodes, the maximum diameter and cortical measures, and Bedi's categorization were recorded. The Mann–Whitney U test was used to compare the collected data and determine the differences between the two groups. As long as the statistical significance threshold was met, the variables were regarded to be of interest to researchers. Results: There was a statistically significant increase in the number of visible nodes, maximal diameter, cortical thickness, and Bedi's classification grade (p 0.001) between the three US examinations. In comparison to patients who had previously been infected with COVID-19, those who were nave to the virus had a greater lymph node response.
