Humoral profiling of pediatric patients with cancer reveals robust immunity following anti‐SARS‐CoV‐2 vaccination superior to natural infection

Abstract

Pediatric patients receiving chemotherapy and those who had previously received chemotherapy had adequate immune activation after both vaccination and acute infection compared to healthy pediatric controls, although there was a demonstrated variability in response for the patients on active chemotherapy. Vaccination against COVID-19 produced superior immune responses compared to acute SARS-CoV-2 infection in pediatric patients with cancer and healthy children, underscoring the importance of vaccination even in previously infected individuals.
