Vaccination and the risk of post-acute sequelae after COVID-19 In the Omicron-predominant period.

Publication date: Feb 06, 2024

To assess the association of primary and third doses of vaccination with the risk of post-acute sequelae of COVID-19. This retrospective cohort study utilized a combined database of nationwide healthcare claims data, COVID-19 patient registry, and vaccination records from South Korea. Individuals diagnosed with COVID-19 in the Omicron variant-dominant period of January to March 2022 were tracked for 30-120 days post-infection. The exposure of interest was the receipt of primary and third doses of the SARS-CoV-2 vaccine. The occurrence of 26 specific conditions in eight domains was compared using Cox regression with inverse probability of treatment weighting. This study included 394,773 unvaccinated individuals and 7,604,081 individuals receiving ≥2 doses of vaccine. Compared with unvaccinated individuals, vaccination with at least two doses was associated with a reduced risk (adjusted hazard ratio; 95% confidence interval) of several conditions, including ischemic heart disease (0. 73; 0. 57-0. 94), heart failure (0. 55; 0. 48-0. 63), cardiac dysrhythmia (0. 72; 0. 61-0. 85), cardiac arrest (0. 41; 0. 33-0. 51), pulmonary embolism (0. 66; 0. 52-0. 84), venous thromboembolism (0. 54; 0. 44-0. 66), acute renal failure (0. 56; 0. 46-0. 67), new dialysis (0. 45; 0. 34-0. 59), chronic obstructive pulmonary disease (0. 74; 0. 65-0. 84), acute pancreatitis (0. 64; 0. 51-0. 80), and diabetes (0. 82; 0. 71-0. 95). The risks of heart failure, cardiac dysrhythmias, cardiac arrest, pulmonary embolism, and new dialysis were lower in those vaccinated with three doses compared with two doses. Vaccination was associated with a decreased risk of post-acute sequelae of COVID-19, suggesting its potential role in mitigating the indirect impacts of COVID-19.
