What is the definition of Typhoid Vi Polysaccharide Vaccine?

The 'Typhoid Vi Polysaccharide Vaccine' is like a superhero shield for your gut, but instead of battling evil aliens, it fights off the sneaky, spicy villain, Typhoid Fever's polysaccharide disguises. It's the ultimate digestive protection, turning your stomach into a fortress against those yucky bacteria that love to cause a ruckus in your system.
