Plant-based vaccine research development against viral diseases with emphasis on Ebola virus disease: A review study

Ebola virus infection results in the fast onset of severe acute haemorrhagic fever with high mortality. The Ebola virus is labelled as a category A pathogen. Vaccines against the Ebola virus (EBOV) are essential for everyone, and an expansion in the arena of vaccine synthesis; especially, plant-based vaccine development has drawn attention. To express the heterologous protein for plant-based vectors, both RNA and DNA viruses have been adapted. Among the different approaches of plant-based vaccine technologies, the agroinfiltration method, which was initially established to investigate plant-virus interactions, has been considered an effective method to produce monoclonal antibodies against EBOV. The effectiveness of plants as bioreactors of vaccine/monoclonal antibodies development could be well-thought-out to attend the obligatory mandate. The review confers recent progress in the production of plant-based vaccines and antibody treatments against the Ebola virus disease, thereby alleviating public health alarms associated with EBOV.
