The pandemic COVID19, effects on global health, educations, clinical research, human civilization, and the economy. So, it has been an urgency to develop proper vaccines against coronavirus. India emphasis on the most nutritious economically-important number-one-consumption-vegetable, okra, used in many human diseases, is naturally infected by different pathogens and significantly reduces production. Though pesticides are the most effective means of control, but they are expensive and toxic to the environment. So, it will require new and more efficient solutions, technologies, products, and methods. Present pre- and post-treatment with biomedicines; Acacia auriculiformis-extract, prepared from the funicles of Acacia auriculiformis A. Cunn., dissolved in sterile tap water at 1mg/10ml, were applied by foliar spray once daily for 15 days @ 10 ml/plant, against Root-Knot (RK), Yellow Vein Mosaic Virus (YVMV) and Okra Enation Leaf Curl Virus (OELCV) diseases of okra, (Abelmoschus esculentus L. Moench) cv.Ankur-40. The soluble root-proteins were separated by using sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE) and were scanned with a recording densitometer electrophoretic scanner, measuring the molecular weight of proteins. Pre- and post-treatment with high-diluted-biomedicines; Acacia auriculiformis extract, were highly effective in reducing different okra-diseases by synthesis of new pathogenesis-related-protein (PR-proteins), inducing their natural defense-response against pathogens-infection and enhanced their growth as well as protein content of fruits and roots. The high-diluted-biomedicines; Acacia auriculiformis extract, not only used as a potential-biomedical-drugs or vaccine against various plant-diseases, by synthesis of new PR-proteins, increasing natural-defense-response, but also, it may help for the preparation of a vaccine against COVID-19, by increasing immunity and enriching science and technology communications applications, cost-effectiveness and biodiversity conservations as well as bio-economy-applications issues, reviving human civilizations in the old form. And in near future okra may itself be a ‘Potential Biomedicine as well as Vaccine’ and world will return in normal form by defeating COVID-19.
