    Seasonality Matters

    • Optimal Timing: Results suggest that the vaccine performs more effectively in regions with seasonal malaria compared to perennial transmission areas.
    • Seasonal Patterns: In seasonal sites, 82% of malaria episodes occurred in the first six months of follow-up, while only 26% occurred in the initial six months in perennial sites.
    • Vaccination Timing: Since the vaccine is administered just before the malaria season, its protection is more pronounced when malaria is seasonal.
