5. Study Description

Brief Summary
Hand, foot, and mouth disease (HFMD) is a common viral illness in infants and children caused by viruses that belong to the enterovirus genus of the picornavirus family. Although most HFMD cases do not result in serious complications, outbreaks of HFMD caused by enterovirus 71 (EV71) can present with a high rate of neurological complications, including meningoencephalitis, pulmonary complications, and can even cause infant death. HFMD caused by EV71 has become a major emerging infectious disease in Asia and the highly pathogenic potential of EV71 clearly requires the attention of world medical community. Recently, an inactivated vaccine(vero cell) against EV71 has been licensed by SFDA in China, this clinical trial phase Ib is armed to evaluate safety in Chinese healthy children (from 13 to 60 months old) and infants (from 6 to 12 months old) and also provide the evidences for the EV71 vaccine immunogenicity and the probable immunizing dose.
Detailed Description
Hand, foot, and mouth disease (HFMD) is a common viral illness in infants and children caused by viruses that belong to the enterovirus genus of the picornavirus family. Although most HFMD cases do not result in serious complications, outbreaks of HFMD caused by enterovirus 71 (EV71) can present with a high rate of neurological complications, including meningoencephalitis, pulmonary complications, and can even cause infant death. HFMD caused by EV71 has become a major emerging infectious disease in Asia and the highly pathogenic potential of EV71 clearly requires the attention of world medical community. The development of vaccine against EV71 is active and ongoing in Asian countries now. Several studies have examined the effectiveness of inactivated viral vaccines against EV71 in animal model. A wide range of experimental EV71 vaccine approaches have been studied including heat-inactivated or formaldehyde-inactivated virion, EV71 virus-like particles (VLP) , VP1 recombinant protein ,VP1 DNA vaccine , VP1 peptide-based vaccine targeting the neutralizing domain, bacterial or viral vector expressing VP1, and a Vero cell-adapted live attenuated virus. Furthermore, neutralizing antibodies against EV71 have been suggested as one of the most important factors in prevention of the severe EV71 infection. Recently, an inactivated vaccine(vero cell) against EV71 has been licensed by SFDA in China, this clinical trial phase Ib is armed to evaluate safety in Chinese healthy children and infants and also provide the evidences for the EV71 vaccine immunogenicity and the probable immunizing dose.
