Publication date: Jun 27, 2023

In the Republic of Korea (Korea), the NVX-CoV2373 (Novavax) coronavirus disease 2019 (COVID-19) vaccination was administered to 18-year-olds and over from February 14, 2022. This study sought to assess the frequency and severity of reported adverse events following the Novavax COVID-19 vaccination in Korea. Adverse events based on two national vaccine safety data were analyzed; the COVID-19 vaccination management system (CVMS) and the text-message survey (TMS). CVMS identified that the reporting rate of adverse events per 100,000 doses were lower after booster doses (84. 0) than after dose 1 (254. 6) or dose 2 (272. 9); and in 65-year-olds and over (83. 4) than in 18- to 64-year-olds (168. 1). The TMS found that local and systemic adverse events were lower in 65-year-olds and over than in 18- to 64-year-olds (p
