Not sure why the kelhus post was flagged. Here is a link to the actual paper, which is in a reputable journal:
There are of course some limitations in extrapolating the results of this study in a lab to real life. Kelhus, if I’m not mistaken, is well aware of what they are and even if he isn’t, the authors of the study describe some of these issues in the paper itself.
I’m also not sure that there is anything in this study that would strongly support altering current vaccination recommendations. It’s possible I missed something, which if I did, I’m sure our buddy Kelhus will chime in. I only spent about 2 min skimming it.
