Quizplus · Accepted Answer

Vaccines stimulate the immune system to produce a primary response to a specific pathogen. This allows for a faster and stronger response if the individual is exposed to that pathogen again in the future. In the case of the chickenpox vaccine, the vaccine introduces a weakened or dead form of the virus into the body, allowing the immune system to build up immunity to the virus. If the vaccinated child is exposed to the virus again through contact with infected individuals, their immune system will recognize it and respond quickly to prevent illness.
