The plant-based vaccine production method works by isolating a specific antigen protein, one that triggers a human immune response from the targeted virus. A gene from the protein is transferred to bacteria, which are then used to “infect” plant cells. The plants then start producing the exact protein that will be used for vaccinations. [6]
