NEW YORK – A research team from the US and Spain has identified distinct immune responses, viral load features, and other differences in infants and young children who experience more severe respiratory syncytial virus (RSV) infections.
Overall, the results "suggest that robust innate immune responses are associated with mild RSV infection in infants," co-corresponding authors Asuncion Mejias and Octavio Ramilo, with the Research Institute at Nationwide Children's Hospital Center for Vaccines and Immunity, and their colleagues reported.
