The patient's past medical history included Illness anxiety disorder. The patient's past medical treatment(s), vaccination(s) and family history were not provided.  On an unknown date in March 2025, the patient received an unknown dose (dose 1) of suspect Rabies vaccine inact (chick embryo) on day 0 (unknown formulation) not produced by Sanofi Pasteur for prophylactic vaccination (Immunisation) and received an unknown dose (dose 2) of suspect rabies (HDC) vaccine (formulation: Powder and solvent for suspension for injection) for rabies (Rabies immunization) on day 7 both (lot number, strength and expiry date not reported) via unknown route in unknown administration site since they missed day 3 (routine immunisation schedule not administered) (unknown latency).

Relevant laboratory test results included: Weight decreased - On an unknown date in 2025:  [lost 20 pounds].  Reportedly, They had a bat in their kitchen and their doctor recommended that they get vaccination just in case. Patient stated that they got their vaccination around 11-Mar-2025. Since getting the 2nd dose, which they think was IMOVAX, they have been very sick and have been in and out of hospital. They said that it was hard to say if some of the side effects that they were experiencing could be due to the other medications they were put on due to the side effects they were experiencing. But the really bad ringing in my ears that persisted has been since the injection. The first 2 months were bad, they could not eat or sleep and experiencing tremors. They mention that they have never been vaccinated before and they have always been kind of hypochondriac. So that may be where the anxiety is from and may be it was their body being unused with vaccination.  Action taken was not applicable.  It was not reported if the patient received a corrective treatment for the events (illness, hallucination, chest pain, palpitations, insomnia, weight decreased, tremor, anxiety, tinnitus and eating disorder).
