Abstract
Nepal started the COVID-19 vaccination on 27 January 2021 with AstraZeneca/Oxford Coronavirus Disease-19 AZD1222 (Covishield) vaccine to control the Coronavirus disease pandemic. The vaccine has a good safety profile, with cardiovascular complications being rare. Herein we report a rare case of cardiovascular complication following Covishield vaccination in a 33 years old female who had dizziness and elevated blood pressure immediately following vaccination and abnormal electrocardiogram showing T wave inversions followed by left bundle branch block. The patient was kept on observation, following which the blood pressure and electrocardiogram changes were normal by seven days. This cardiovascular complication following the vaccination demands further investigation into the adverse event of the vaccine. However, since the benefit of the vaccine outweighs the risk, World Health Organization has recommended the continuity of the vaccine as of now.
