You conveniently left out:
We report two cases of SE related to the SARS-CoV-2 vaccine. In addition, we performed a systematic search of the literature to identify the consistency of the association between the SARS-CoV-2 vaccine and the SE onset. The following databases were consulted: PubMed and Google Scholar.
So two cases out of how many vaccines given?
AND you seem to be ignoring the fact that there was a whole study published about those two cases...
Which is interesting in and of itself given you chief complaint this thread has been the medical field ignoring/denying vaccine side effects.
Preprints are preliminary reports of work that have not been certified by peer review. They should not be relied on to guide clinical practice or health-related behavior and should not be reported in news media as established information.
