Omicron escapes the majority of existing SARS-CoV-2 neutralizing antibodies

Yunlong Cao et al.

Summary: The Omicron variant of SARS-CoV-2 contains 15 mutations in the receptor-binding domain, leading to evasion of over 85% of tested neutralizing antibodies. Different epitope groups of neutralizing antibodies are affected to varying degrees by single mutations of Omicron. Antibodies targeting the conserved region of sarbecovirus remain most effective against Omicron.

Summary: This study assesses the settings and activities associated with SARS-CoV-2 infection in the context of the Delta variant circulation in France. It also investigates the protection against symptomatic Delta infection. The study finds that bars and parties are associated with increased risk of infection for individuals under 40 years old, while daycare, kindergarten, primary school, and middle school attendance are associated with increased risk of infection for those aged 40 and older. The study also highlights reduced vaccine effectiveness against symptomatic Delta infections and the importance of reinforcing individual and public health measures in high-risk settings and activities.

Aging in COVID-19: Vulnerability, immunity and intervention

Yiyin Chen et al.

Summary: The COVID-19 pandemic originating from Wuhan in December 2019 has had far-reaching health and socioeconomic impacts worldwide. The disease caused by SARS-CoV-2 is highly heterogeneous, with age, gender, and comorbidities playing key roles in disease severity and outcomes. Aging and dysregulation of immune function are thought to contribute to the increased vulnerability of older adults to severe COVID-19. Further research on immune responses to SARS-CoV-2 infection, particularly in different age groups, is crucial for understanding disease heterogeneity and developing effective vaccines.

Wenlong Zhu et al.

Summary: From January 2 to February 14, 2021, a local outbreak of COVID-19 occurred in the city of Shijiazhuang, with 869 symptomatic cases reported. Most cases were confirmed before January 20. The estimated incubation period was 11.6 days, and the estimated serial interval was 6.6 days. Simulation results suggested that a longer incubation period would lead to a longer epidemic period, and reducing quarantine measures would require increased nucleic acid testing to minimize cases.
