Scientists at Hyderabad's CCMB-LaCONES have called for region-specific snake antivenoms, citing research showing that venom profiles vary geographically. Their findings indicate that standard polyvalent antivenom may not effectively neutralise venom from regional krait populations in North-East India. Hyderabad: It may sound strange, but according to top scientists from Hyderabad, the country needs a region-specific snake antivenom optimized for snake bite victims based on their geographical location.
