[Case] A 28-year-old man presented with fatigue, headache, bilateral shoulder pain, chills, and diarrhea. Although he was healthy, his symptoms appeared on the day after vaccination with his second dose of the Pfizer-BioNTech vaccine. He visited our outpatient clinic for Kampo medicine treatment on day 10. Based on the clinical course, the patient was considered to have vaccine- induced side effects, and keishito was prescribed according to the Eastern medicine findings. On day 13, his sweating disappeared, and headache and chills showed improvement;however, shoulder pain and fatigue persisted. On day 27, purple spots on the tongue were considered blood stasis, so the patient was prescribed tsudosan, which improved his shoulder pain. On day 52, the numeric rating scale score was 1 point, indicating a trend toward improvement. [Discussion] Side effects are typically common following vaccination as the body is building immunity to antigens;however, they usually subside within a few days. Western medicine alone cannot maintain the quality of life of patients experiencing prolonged symptoms. [Conclusions] Kampo medicine can be used to develop complementary medical treatments, even in clinical areas where evidence is yet to be accumulated.
