COVID-19 Vaccine Booster Dose Fails to Enhance Antibody Response to Omicron Variant in Reinfected Healthcare Workers

This Spanish study, funded by Roche Diagnostics and led by Leire Fernández-Ciriza from Clínica Universidad de Navarra, Pamplona, and colleagues, explores the immune response to COVID-19 booster doses in healthcare workers, focusing on reinfection and primary vaccination schedules. Researchers aimed to determine whether booster doses enhanced antibody responses to the Omicron variant, particularly in those with prior infections.
