Q. What is the total number of immunological components received in the 14 childhood vaccines that are given today?

A. About 10
B. About 150
C. About 500
D. About 1,000




The correct answer is B. About 150
Children born in 1942 received four vaccines that contained more than 3,000 immunologic components. Improvements in lab techniques have allowed scientists to use only the parts of viruses and bacteria that are needed to generate immunity. Today, routinely recommended childhood vaccines contain only about 150 immunological components.
