Hi Esther12. Yes, that is my impression too, this study is about the emotional effects of vaccine-induced inflammation, not the beliefs of patients (and nothing specific to do with ME/CFS). I did not mean to imply this specific study will be used against ME/CFS patients, but rather the mechanisms involved are in a field which is creatively interpreted for hypotheses. For example, interleukin-6, the cytokine important to this study, can also be elevated in response to psychological stress.
