Article Synopsis
- This study analyzed over 2 million people in South Korea to compare the effectiveness of COVID-19 bivalent vaccines versus monovalent vaccines in preventing severe infections and deaths.
- Bivalent vaccine recipients showed much lower rates of infection, critical illness, and death compared to those who received monovalent vaccines, with effectiveness rates up to 85.3% against death shortly after vaccination.
- The findings suggest that bivalent vaccines offer significant additional protection during the omicron variant phase of the pandemic, demonstrating sustained effectiveness over time.
Article Synopsis
- This study aimed to evaluate the effectiveness of bivalent versus monovalent COVID-19 vaccines during the 2022-2023 winter using real-world data from South Korea.
- The research included 29,245 adults and found that bivalent vaccine recipients had a 12.2% higher protection against COVID-19 compared to those receiving the monovalent vaccine, especially noted at 39.4% for individuals in long-term care facilities.
- The study concludes that bivalent vaccines offer superior protection, suggesting they should be prioritized in immunization programs to combat seasonal COVID-19 outbreaks.
This study aimed to identify the stress level, knowledge, attitude, and infection control performance of nurses at long-term care hospitals (LTCHs) designated for infectious disease management and to investigate factors contributing to infection control performance. A total of 178 nurses who had worked for at least 1 month at seven LTCHs designated for infectious disease management and provided care for patients confirmed with COVID-19 were enrolled in the study. Data were collected from February to March 2022 using written and online self-report questionnaires.
