Multi-Pathogen Innovative (5 in 1) Vaccine for Viral Haemorrhagic Fevers will Save More Lives.

Mankind has developed strategies to mitigate calamitous pandemics, by using vaccines. Eradication of some diseases was successful through usage of vaccines. Lassa, Yellow, Crimean-Congo, Marburg and Ebola viruses need special attention. Lassa fever, that now has a candidate vaccine, was discovered in 1969 when two missionary nurses died in Nigeria, while Yellow fever has a vaccine from its 17D attenuated strain. Crimean-Congo haemorrhagic fever is a widespread tick-borne viral disease, and the nucleoprotein and glycoproteins are identified for inclusion in a vaccine. Marburg virus is highly pathogenic with mortality rate of 90%. Ebola virus outbreak in West Africa in 2013-2016 necessitated an early introduction of a vaccine. The classical vaccine platforms are commonly used for human vaccines, and next-generation platforms, are being developed. Development of a novel multivalent vaccine against viral haemorrhagic fevers will eliminate the difficulties of single vaccines and may lead to the eradication of these diseases.
