title: Immune responses to baculovirus-displayed enterovirus 71 VP1 antigen.
abstract: The increased distribution and neurovirulence of enterovirus 71 is an important health threat for young children in Asia Pacific. Vaccine design has concentrated on inactivated virus with the most advanced undergoing Phase III clinical trials. By using a subunit vaccine approach, production costs could be reduced by lowering the need for biocontainment. In addition, novel mutations could be rapidly incorporated to reflect the emergence of new enterovirus 71 subgenogroups. To circumvent the problems associated with conventional subunit vaccines, the antigen can be displayed on a viral vector that conveys stability and facilitates purification. Additional advantages of viral-vectored subunit vaccines are their ability to stimulate the innate immune system by transducing cells and the possibility of oral or nasal delivery, which dispenses with the need for syringes and medical personnel. Baculovirus-displayed VP1 combines all these benefits with protection that is as efficient as inactivated virus.
