Answer:

1. A lymphocyte is a type of white blood cell in the vertebrate immune system. Lymphocytes include natural killer cells, T cells, and B cells. They are the main type of cell found in lymph, which prompted the name "lymphocyte". Lymphocyte makes up between 18% and 42% of circulating leukocytes.

2.A vaccine is a biological preparation that provides active acquired immunity to a particular infectious disease. A vaccine typically contains an agent that resembles a disease-causing microorganism and is often made from weakened or killed forms of the microbe, its toxins, or one of its surface proteins
