Answer 1

Answer: (B)

Primary immune response

When the body first encounter with a specific pathogen some lymphocytes differentiates to form memory cells that have the ability to confer long-lasting immunity to that pathogen, often for life is called as primary immune response. These memory cells recognize antigens on the pathogens they have encountered before, triggering the immune system to respond faster and more effectively than on the first exposure. So, immune system retains the memory of the primary immune response, when vaccinated.
Therefore, the correct answer is option B.
