Q: What chemical compound is used during the manufacture of vaccines to inactivate viruses or bacterial toxins?

A. Water
B. Formaldehyde
C. Aluminum
D. Gelatin


The correct answer is B. Formaldehyde
Formaldehyde is used during vaccine manufacturing to inactivate viruses and bacterial toxins. Some concern surrounds the use of formaldehyde in vaccines because it is also used to preserve dead bodies. However, the amount of formaldehyde in vaccines is minimal because of purification processes used during the manufacturing process.
