What vaccine is used for polio prevention?

The correct answer is the polio vaccine, which is specifically designed to prevent poliomyelitis, a highly contagious viral infection that can lead to paralysis and other severe complications. This vaccine works by stimulating the immune system to produce a response against the poliovirus, effectively reducing the risk of infection and transmission.

Other vaccines mentioned serve different purposes; for instance, the DTP vaccine protects against diphtheria, tetanus, and pertussis (whooping cough), while the MMR vaccine offers protection against measles, mumps, and rubella. The Hepatitis B vaccine is aimed at preventing infection from the hepatitis B virus. Each of these vaccines is crucial for public health but does not provide protection specifically against poliovirus, underscoring the importance of the polio vaccine as the targeted solution for polio prevention.
