: A recent publication has sought to describe the influence of the COVID-19 vaccine on ipsilateral axillary lymph node features, comparing their nodal basal features with their characteristics after the first and second vaccination dose (Igual-Rouilleault AC, Soriano I, Quan PL, Fernández-Montero A, Elizalde A, Pina L (2021) Unilateral axillary adenopathy induced by COVID-19 vaccine: US follow-up evaluation. Eur Radiol. DOI: 10.1007/s00330-021-08309-7). The 91 patients included in the cohort of this publication have also been included in this new research representing approximately 37% of the sample. However, in this project, our objective was to assess ultrasound characteristics of ipsilateral axillary lymph nodes after two doses of four different COVID-19 vaccination protocols—mRNA (Pfizer, Moderna), AstraZeneca, and mix-and-match (AstraZeneca and Pfizer)—and to determine also whether these parameters differed with age and how they changed on follow-up imaging.
