which type of immunity do vaccines provide?
○ active natural

Explanation:

Question 19

Fever, allergies, and local injection - site reactions are known side effects of vaccines. Scientific research has thoroughly debunked the myth that vaccines cause autism; there is no causal link between vaccines and autism.

Vaccines introduce a weakened or inactivated form of a pathogen (or part of it) into the body. This stimulates the immune system to produce an immune response (active immunity) and is done artificially (through vaccination, not natural exposure like getting an infection). So vaccines provide active artificial immunity.

Answer:

D. autism
