RESUMO
The main pathogen causing severe and neurotrophic hand, foot and mouth disease (HFMD) is enterovirus A71 (EV71). EV71 infection is among the major cause of serious public health burden and economic loss especially in the Asia-pacific region. Yet, no specific anti-viral treatment against this life-threatening infection is currently available. Thus, the best way to control EV71 infection is by vaccination with an effective and safe vaccine. Several strategies are being employed to develop vaccines against EV71. These include conventional and modern recombinant vaccine strategies. Conventional vaccines such as inactivated EV71 vaccines are the most studied and advanced vaccines against HFMD. Recombinant HFMD vaccines developed based on the recombinant DNA technology have been employed but are mostly at early or late preclinical development stage. In this article, we discuss the recent progress and advances in modern recombinant strategies of EV71 vaccine development including subunit, VLP, epitope-based, DNA, and vector-based vaccines, as well as conventional approaches, focusing on their various prospects, advantages and disadvantages.
