University of Michigan spin-off NanoBio Corporation has received its second grant for vaccine development from the Bill and Melinda Gates Foundation. The new $6 million grant is for development of an intranasal vaccine for respiratory syncytial virus (RSV). No approved RSV vaccines are available currently.
