Question

Quizplus · Accepted Answer

Vaccines contain a weakened or dead form of the virus or bacterium that causes the disease they protect against, which triggers the body's immune response to produce antibodies. This primes the immune system so that it can effectively respond to a future infection from the live virus or bacterium. The first exposure from the vaccine is not sufficient to provide complete protection, but it does kickstart the immune system's response.
