Chao says that silkworms are capable of producing a broad range of genetically engineered proteins, including animal vaccines (such as a swine fever vaccine), food and nutritional additives (which can replace antibiotics), antimicrobial additives (which can be used instead of preservatives in cosmetics), protein reagents, proteins with laboratory and industrial applications, and even vaccines for people.
趙裕展指出，家蠶能「生產」的基因工程蛋白範圍甚廣，包括動物疫苗（如豬瘟病毒疫苗）、飼料營養添加物（可取代抗生素）、抗菌需求添加物（如用在化妝品中，取代防腐劑）、檢驗試劑蛋白、實驗室用蛋白、工業用蛋白，甚至人類用的疫苗等等。
