Story summary

Researchers developed a recombinant antivenom using nanobodies from alpacas and llamas for sub-Saharan Africa.
The treatment neutralized toxins from 17 of 18 tested snake species, surpassing Inoserp PAN-AFRICA.
Nanobodies are smaller, more stable, and less likely to cause adverse reactions than traditional antivenoms.
Further optimization and clinical trials are planned to improve rural access and address over 300,000 snakebites annually.
