加拿大这个植物系疫苗的原理相当神奇。用的还真是烟草叶子。而且植物和人类的DNA差距太大了,理论安全性应该相当不错。
We use a plant-based platform to develop our vaccines. This approach uses living plants as bioreactors to produce non-infectious versions of viruses (called Virus-like Particles, or VLPs). Learn more about our proprietary plant-based platform
here.
We use VLPs that mimic the architecture of a virus but are non-infectious. The VLPs present antigens to the individual's immune system in a highly efficient manner, eliciting a protective and long-lasting immune response.
We successfully produced a VLP of the coronavirus in early March 2020, just 20 days after obtaining the SARS-CoV-2 (the virus causing the COVID-19 disease), as announced
here.
