SARS-CoV-2 antibody responses in children exhibit higher FcR engagement and avidity than in adults
Overview
Paper Summary
In a study of children and adults with mild or asymptomatic COVID-19, children had lower overall antibody levels but their antibodies were better at grabbing onto the virus and activating other immune cells. These differences seem to be driven by children generating a new, targeted response to SARS-CoV-2, while adults' responses may be influenced by past encounters with other coronaviruses.
Explain Like I'm Five
Kids make better antibodies to fight COVID than adults! Their antibodies grab the virus tighter and call for help from other immune cells more effectively.
Possible Conflicts of Interest
LLM Poon, M Peiris, and SA Valkenburg have a patent pending related to the use of ORF8 as a diagnostic for SARS-CoV-2 infection. M Mori produced ORF8 protein using a patented process. Other authors declared no conflicts.
Identified Limitations
Rating Explanation
This study is methodologically strong with a large, well-characterized cohort. The findings regarding the distinct antibody responses in children are novel and have important implications for understanding and treating COVID-19. The exclusion of severe cases and focus on early pandemic samples are limitations that prevent a rating of 5.
