Abstract:
Background: Young woman without any prior history of mental illness developed psychotic symptoms shortly after receiving the Astra Zeneca covid-19 vaccine. Aims: The case to be discussed in this paper was chosen due to the rarity of the presenting complaint and to explore all possible avenues of the presenting complaint without agenda to determine most likely cause.

Method: Case study of investigations and analysis of treating team looking after the patient.

Results: The patient developed encephalitis following administration of AZ CV-19 vaccine which appeared to trigger a psychotic episode. Following treatment of the encephalitis, the psychotic symptoms remained in absence of the suspected organic cause, indicating that the psychosis was present independent of the original trigger.

Conclusions: The interpretations of the findings suggested that had the patient not received this vaccine, she would not have experienced the side-effect of encephalitis which resulted in her development of psychosis which required ongoing treatment in the community to treat.
