人体中存在免疫系统,由淋巴细胞 B 形成的抗体(例如免疫蛋白)就是免疫系统中的一员。免疫球蛋白能与肌体的入侵物(抗原)结合使之惰性化,从而消除入侵物的影响。向人体内输送疫苗可以增强免疫系统的能力,从而能防御疾病。例如,种牛痘可以预防天花,注射卡介苗可以预防肺结核。在过去,向人体内输入疫苗的方法只有注射和接种,而在90年代中期,科学家们推出了可以食用的植物性疫苗,使得今后口服植物性疫苗将逐渐取代上述两种传统的方法。植物性疫苗的优点在哪里植物疫苗也称食用疫苗,它可以通过口服进入人体。植物疫
The body’s immune system, the formation of antibodies by lymphocytes B (such as immune proteins) is a member of the immune system. Immune globulin with the body’s invasion (antigen) to make it inert, thereby eliminating the impact of invasion. Vaccination into the human body can boost the immune system’s ability to defend against the disease. For example, cow vaccination can prevent smallpox, BCG injection can prevent tuberculosis. In the past, vaccination was only injected and vaccinated into the human body. In the mid-1990s, however, scientists introduced edible plant-based vaccines, so that oral vaccines will gradually replace the two traditional methods described above. The Advantages of Phytosanitary Vaccines Phytosanitary vaccines, also known as edible vaccines, can be administered orally to the human body. Plant disease
