You appear to be attempting to link to a specific study, however that study is not accessible from your link. It's possible you were trying to reference this study: https://pubmed.ncbi.nlm.nih.gov/11868925/, which was done on 36 (human) participants at the University of CT in 2002. Full paper available at: https://sci-hub.scrongyao.com/10.1016/S1081-1206(10)61996-5

I'm not certain that a paper with 36 participants would be representative of all humans.

Searching PubMed non-exhaustively for "honey" and "allergies" yields this paper, Allergies and Natural Alternatives (https://doi.org/10.1016/j.otc.2022.06.005), states, amongst other things, that "The efficacy of these therapies is varied and under-researched." Alas, this seems to be the case.
