title: EV71 vaccines: a first step towards multivalent hand, foot and mouth disease vaccines.
abstract: Enterovirus A infections are the primary cause of hand, foot and mouth disease in infants and young children. Enterovirus 71 (EV71) and coxsackievirus A16 have emerged as neurotropic viruses responsible for severe neurological complications and a serious public health threat across the Asia-Pacific region. Formalin-inactivated EV71 vaccines have elicited protection against EV71 but not against coxsackievirus A16 infections. The development of a bivalent formalin-inactivated EV71/FI coxsackievirus A16 vaccine should be the next step towards that of multivalent hand, foot and mouth disease vaccines which should ultimately include other prevalent pathogenic coxsackieviruses and echovirus 30. This editorial summarizes the major challenges faced by the development of hand, foot and mouth disease vaccines.
