What type of immunity do vaccines provide?
Correct answer
A
Rationale
Vaccines provide active immunity by stimulating the immune system to produce antibodies against specific pathogens. Choice B, passive immunity, is acquired from ready-made antibodies, not through vaccination. Choice C, transplacental immunity, is a form of passive immunity transferred from mother to infant, not acquired through vaccines. Therefore, the correct answer is active immunity.
