Coronavirus Disease 2019 (COVID-19) has been a global issue till date since its discovery in December 2019. As part of the interventions to end this pandemic, multiple vaccines are formulated and studied worldwide. Vaccine constitutes the most effective measure in public health, preventing the spread of infectious diseases as well as reducing the mortality rate. Similar to any medication, allergic reaction is part of the adverse reactions in vaccine. Anaphylactic reaction is uncommon post vaccination; however, it is potentially life-threatening. We describe a case of anaphylactic shock post CoronaVac vaccination, first ever case reported in Malaysia.
