Introduction:
Several types of vaccine have been shown to significantly reduce the risk of severe coronavirus disease 2019 (COVID-19). This study aims to report the first case of meningoencephalitis after receiving the second dose of Pfizer COVID-19 vaccine.
Case Report:
A 62-year-old lady presented with headache, fever and rigor for 4 days. She had acute confessional state and inability to talk. She was conscious, disoriented, not obeying commands. Acyclovir vial IV 750 mg three times a day for 14 days were prescribed. She responded very well.
Discussion:
Concern has been raised about the safety of vaccinations. The most common side effects of COVID-19 vaccinations are local responses at the injection site, followed by non-specific systemic symptoms such as headache, tiredness, myalgia, and fever. These may appear shortly after immunization and disappear in a short period of time.
Conclusion:
Although extremely rare, aseptic meningoencephalitis could occur after COVID-19 vaccination. The patient could be managed conservatively with a good clinical outcome.
