The first six months of life reflects a time of high susceptibility to severe disease following respiratory virus infection. While this could be significantly improved by immunization, current vaccines are not approved for use in these very young individuals. This is the result of the combined effects of poor immune responsiveness and safety concerns regarding the use of live attenuated vaccines or potent adjuvants in this population. Vaccines to effectively combat respiratory viral infection would ideally result in robust CD4+ and CD8+ T cell responses as well high affinity antibody. Inclusion of TLR agonists or single cycle viruses are attractive approaches for provision of signals that can act as potent stimulators of DC maturation as well as direct activators of T and/or B cells. Here we discuss the challenges associated with generation of a robust immune response in neonates and the potential for adjuvants to overcome these obstacles.
