Question

what is the goal of a vaccine? (1 point)
to infect your body with a virus to kill off weak/ unprepared cells.
to perform scientific experimentation on humans in real time.
to cause your immune system to create antibodies prior to an infection by a virus.
to allow your immune system to effectively kill off bacterial infections.

Explanation:

Vaccines contain weakened or inactivated forms of pathogens (like viruses). They stimulate the immune system to produce antibodies against the pathogen. This way, if the actual pathogen infects the body later, the immune system can recognize and fight it off more effectively.

Answer:

To cause your immune system to create antibodies prior to an infection by a virus.
