The trial enrolled over 4,800 children across five sub-Saharan African countries and demonstrated durable protection over a 24-month follow-up period with a favourable safety profile.

The developers have applied for WHO prequalification and are in discussions with the GAVI vaccine alliance about accelerated deployment in high-burden countries, potentially reaching 40 million doses annually within three years.
