preventing infectious diseases by stimulating the immune system to produce an immune response without causing the disease itself. This helps protect individuals and communities by building immunity and reducing the spread of diseases.
artificial active immunity
When the Spanish took over Mexico, they brought along with them many diseases that are in part responsible for the defeat of the indigenous population of Mexico. Once they became infected, it was an immediate death for the Indians, since they had no source of immunity or protection against the infectious diseases. No immunity meant that a large portion of the Indian population would be affected and soon die off.
