Concomitant medications were not provided by the reporter.   Fever started 1 day after vaccine administration and was episodic, lasting for minutes to hours and recurring throughout the day. Over the next 48 hours, the patient developed a generalized body rash, starting from the trunk and spreading to the extremities. Thereafter, he began to experience headache, dizziness and double vision, which later progressed gradually to severe encephalopathy in the course of 5 days. On dermatological examination, he was noted to have deep red, non-scaly, oedematous papules coalescing into plaques on the abdomen, upper chest, proximal upper extremities, bilateral upper flanks and back, with scattered non-follicular pustules. On neurological examination, he had intermittent and irregular orofacial movements and bilateral upper extremity myoclonus.  The patients HIV-1 was non- reactive. The patient was also evaluated for Lyme disease, Rickettsia and Typhus on basis of IgG/IgM titers showing negative results. Other antibody test included were Smith, Ro, La and, Anti Jo-1 IgG and all were negative. Autoimmune encephalitis panel result: ANNA 1 (Hu), ANNA 2 (Ri), ANNA 3, PCA1 (Yo), PCA2, PCA- Tr (DNER), AGNA/SOX1, amphiphysin, CRMP5/CV2, GAD65, Ma2/Ta, Myelin Ab, aquaporin 4, NMDAR1, AMPAR1, AMPAR2, GABABR, LGI1, CASPR2, DPPX Rec, VGKC all were negative.  Evaluation for malignancy was unrevealing, including serum protein electrophoresis, peripheral blood smear, peripheral blood flow cytometry, and CT of chest, abdomen and pelvis.  Treatment was not provided for rest of the events.
