Summary

This study looked at whether a single dose of the TV003 dengue vaccine or a past Zika infection could protect people from getting infected with Zika virus again. 27 healthy adults took part. Researchers gave them the vaccine or used people who had Zika before, then exposed them to a controlled Zika virus to see if they got infected. The goal is to find ways to prevent Zika, especially to protect pregnant women and their babies from birth defects.
