Have you ever heard of llama nanobodies? Scientists have discovered that these tiny molecules are capable of neutralizing noroviruses, which are the leading cause of foodborne illness in the world. The results of this study provide hope for a much needed norovirus vaccine. The nanobodies are derived from llamas, which possess a unique immune system that allows them to create antibodies that are smaller than those of humans. These nanobodies can bind to norovirus and deactivate it, preventing it from causing infection. This discovery could lead to a new form of vaccine that could be used to protect people from norovirus.
