Respiratory syncytial virus (RSV), a common cause of pneumonia and bronchiolitis, currently has no effective vaccine. Researchers at Vanderbilt University are developing a new vaccine using gold nanorods to deliver the detrimental F protein to immune cells prior to infection. In this manner, immune cells can be prepared for a real infection. The gold nanorods are similar in size and shape to actual RSV and coated with the F protein. Results of research on dendritic cell samples have shown rapid multiplication of T-cells after introduction of the new compounds.
