Natural reinfection with respiratory syncytial virus varies based on antibody response
Researchers at Baylor College of Medicine found that while most individuals responded to respiratory syncytial virus (RSV) natural reinfection with a typical sustained antibody response associated with protection, a few individuals surprisingly responded atypically, not being able to sustain the antibody response, which declined to levels that made the individuals susceptible to RSV reinfection.
The researchers highlight in their study, published in the journal
Vaccine, that their findings point at a subpopulation of people who also may not maintain an antibody response to vaccines and suggest the need to characterize patient-specific responses to respiratory viral infections, such as COVID-19.
