Question

What primary advantage do edible vaccines offer in terms of human immune response compared to traditional injected vaccines?

Options

• They eliminate the requirement of antigen presentation by host lymphocytes

• They stimulate both mucosal immunity and systemic immunity without requiring an injection

• They permanently alter the host genome to prevent all viral replication

• They completely bypass the gastrointestinal immune cells

Answer 1

Consuming transgenic plants delivers the expressed antigen directly to immune cells in the gut, thereby stimulating both mucosal immunity and systemic immunity without the need for needles or cold chains.
