@castilevscancer: 🎗️ "Today was Castiel's second dose of the bivalent anti-GD2/GD3 neuroblastoma vaccine. It's tiring, it's hard watching him go through this again —but every step is one more step forward in his fight. Please keep praying for us, every prayer has made a real difference in this journey.
