Objectives

Narrative objectives1

In this study, 28 patients who were diagnosed with ME/CFS after COVID-19 vaccination and whose blood vitamin levels were measured and found to be deficient or insufficient were instructed to consume vitamin D-rich foods (including supplements) and their blood vitamin levels were monitored. Checking diagnostic criteria for ME/CFS, we investigated the clinical course of each case in detail from the medical records, including patient background, medical history, COVID-19 vaccination history, laboratory values, and treatment history, and examined the efficacy of the above medical therapy.
