Summary

This trial involves injecting healthy adults with a small dose of the Zika virus to study their immune response. The goal is to find the best virus strain and dose for future vaccine development. Participants are healthy adults who have never been exposed to Zika or Dengue viruses.

Who is the study for?
This trial is for healthy men and women aged 18-40 who have never had Zika or Dengue virus, are not pregnant, and agree to use contraception. Women on hormonal birth control must avoid medications that reduce its effectiveness. Participants must be in good health, able to stay in the hospital for up to 16 days post-inoculation, and follow CDC guidelines for contraception.
What is being tested?
The study tests two strains of the Zika virus (ZIKV-SJRP/2016-184 and ZIKV-Nicaragua/2016) against a placebo in four groups of volunteers. Each group receives different doses with ten subjects getting the virus strain and four receiving a placebo. The aim is to evaluate these strains' suitability for future research.
What are the potential side effects?
Potential side effects may include typical responses to viral infections such as fever, rash, joint pain, muscle pain, headaches or conjunctivitis (red eyes). There's also a risk of more serious complications like Guillain-Barré syndrome but this will be closely monitored.

Mechanism Of Action

Other Research
Common treatments for Zika Virus primarily focus on symptom management and supporting the immune response. Antiviral medications, although not specifically approved for Zika, work by inhibiting the virus's ability to replicate. Immune-based therapies, such as monoclonal antibodies, directly target and neutralize the virus. These mechanisms are important for Zika Virus patients as they help in reducing the viral load, potentially leading to better clinical outcomes and faster recovery.
