The viruses with truncated NS1 are highly immunogenic because interferon acts as an adjuvant by enhancing the production of immunoglobulins and contributing to the activation of dendritic cells required for antigen presentation. The robust immune response to these viruses could make it possible to scale down the amount of infectious agents in each dose by several orders of magnitude; many more doses could be manufactured in this way, Dr.
