About
KAICO Ltd. is a biotechnology startup originating from Kyushu University, founded in 2018, with a mission to deliver silkworm-derived pharmaceuticals and vaccines to the world. The company's core platform — the silkworm-baculovirus expression system — uses silkworm pupae as natural bioreactors to produce high-quality recombinant proteins without the infrastructure required by traditional biomanufacturing. KAICO offers custom protein expression services, research reagents, and develops both animal and human vaccines including an oral (edible) vaccine for pigs already in commercial use. The company has received government research funding for next-generation pandemic vaccine modalities and is expanding internationally across Asia through distribution partnerships.
