How do vaccinations prevent disease? (A) They increase the inflammation process - HSC - SSCE Biology - Question 6 - 2012 - Paper 1

Vaccinations work by stimulating the immune system to produce antibodies against specific pathogens. When a person receives a vaccine, they are introduced to a harmless component or a weakened form of the pathogen. This exposure prompts the body to generate a robust immune response, increasing the production of antibodies that specifically target that pathogen. As a result, if the vaccinated individual is later exposed to the actual disease-causing organism, their immune system can rapidly recognize and combat the infection effectively.
