Outbreak of Zika virus pathogenesis and quest of its vaccine development: Where do we stand now?

Zika virus (ZIKV) infection is a life-threatening tropical infection, mainly caused by mosquito bite. After a very long period of quietness, ZIKV infections have become a problematic issue again. Previously, the virus was limited to Africa and Asia only but later it emerged in Brazil, South America, and other parts of the world in 2015. In 2016, there are emerging new cases of sexually transmitted ZIKV infection as well. At present, there is no proper treatment and available pronounced vaccines for the treatment of ZIKV infection. The prime focal point of this review is not only to provide imperative epidemiological information on ZIKV infection in brief but also the current situation of vaccines testing on animal model as well as in clinical trial phases. Currently there is no human vaccine for this pestiferous viral infection. Therefore, prevention, proper management, and up-to-date recommendation are crucial to mitigate the possible risk of vector and non-vector transmission of ZIKV.
