Q8.
Vaccination has been one of the most effective public health interventions, significantly reducing the incidence of infectious diseases worldwide. Vaccines work by stimulating the body's immune system to produce antibodies, providing protection against future infections. Despite their proven efficacy, vaccine hesitancy remains a challenge in achieving widespread immunity.
How do vaccines primarily protect the body from infections?
