Trial Summary

What is the purpose of this trial?

This trial is testing a new vaccine called JCXH-221 in healthy adults aged 18 and older. The vaccine aims to train the immune system to recognize and fight off infections. Researchers are looking to find a safe and effective dose while monitoring the immune response.

Will I have to stop taking my current medications?

The trial requires that you do not take medications that may prevent or treat COVID-19. If you are on such medications, you would need to stop them to participate.
