Part 4/8:
The trial phases involve meticulously determining the optimal vaccine dose—balancing efficacy with tolerability. Phase one focuses on understanding the maximum dose that can be administered before side effects become unacceptable. The goal is to find that "sweet spot" where the immune response is maximized while adverse effects are minimized. Currently, researchers are progressing through their initial dose rounds, with hopes of completing all four doses within the next month. Continued observation over subsequent months will assess both immune response and potential side effects.
