“…The previously described association between VAHL and immunogenicity [14,15] may be implied alsoin the results of the current study. Older age [17] and obesity [18] were both reportedto be associated with weaker vaccine-induced immunity.…”

“…The current study demonstrates that the overall incidence of any-grade VAHL following the third Covid-19 vaccine dose is basically similar to that reported following the rst and second Covid-19 vaccine doses [8][9][10][14][15][16]. However, VAHL cases following the third dose were found to have shorter duration andlow uptake intensity after the rst 5 days from vaccination.…”

“…We concluded that VAHL on imaging may reflect a potent germinal center response in lymph nodes draining the vaccine injection site [14]. The relationship between VAHL and immune status was observed by Eifer et al as well [15].…”

“…Potential pitfalls in the diagnostic of PET/ CT are well known, especially after vaccination [1]. Eifer et al showed FDG-uptake of axillary lymph nodes in 45 % of patients after mRNA-COVID-19 vaccination in the ipsilateral upper arm [2]. Several cases presented high FDG-uptake after COVID-19 vaccination in axillary lymph nodes, mentioning the potential danger in interpreting these lymph nodes correctly, but only few with histopathological confirmation [3,4].…”
