B	white blood cells from an infected individual

Detailed explanation-2: -Cell culture technology has been used to produce other U.S.-licensed vaccines, including vaccines for rotavirus, polio, smallpox, hepatitis, rubella and chickenpox.

Detailed explanation-3: -Pneumococcal vaccine-This vaccine works the same way as the Hib vaccine to create a better immune response than natural infection.
