There are no studies about zika registered at ClinicalTrials.gov or elsewhere (EudraCT, Chi-CTR, others). Predictions about future events are very difficult and only time can determine their accuracy, having said that, we are afraid that there will be no vaccine against zika approved by regulatory agencies anytime soon – perhaps not during this decade.
We look forward to reading phase 1 studies available in public clinical trials registers. Finally, we hope to be wrong about the aforementioned prediction.
