This is one of the shingles vaccines


Active ingredients:

gE antigen: a purified glycoprotein (a protein with a sugar attached to it) from the surface of varicella-zoster virus (the virus that causes chickenpox and shingles). 

This vaccine also contains an adjuvant called AS01b, which contains 2 ingredients: MPL and QS-21. MPL is derived from a species of bacteria called Salmonella minnesota, and QS-21 is derived from the soap bark tree.

Inactive ingredients:

Salts: help maintain the stability and pH of the vaccine

Carbohydrates (sugars): normally used as stabilizers in vaccines

Lipids (fats): lipids do not dissolve in water, so they are used to create a protective coating around the active ingredient. This coating is also called a liposome.

Other Stabilizers:
