Team FIRE brought the heat to ! 🔥🧬

We had a great time sharing our latest flavivirus research posters at yesterday’s session. It was the perfect follow-up to an inspiring talk between Dr. Ruth Karron and former Surgeon General Dr. Jerome Adams on navigating vaccine policy in uncertain times.

At CIR, our FIRE team is passionate about finding vaccines and treaments for viruses like Dengue and Zika—diseases that affect millions of people every year. Sharing our data and connecting with fellow researchers makes all the hard work worth it!
