A	White blood Cells
B	Antibodies
C	Lymph
D	Vaccines

Explanation:

Detailed explanation-1: -Live-attenuated vaccines Live vaccines use a weakened (or attenuated) form of the germ that causes a disease. Because these vaccines are so similar to the natural infection that they help prevent, they create a strong and long-lasting immune response.

Detailed explanation-2: -This led to the development of inactivated vaccines, which are produced by killing the pathogen with chemicals, heat or radiation. One contemporary example is Havrix, an inactivated vaccine against hepatitis A virus that was developed by NIAID and partners and licensed in the United States in 1995.

Detailed explanation-3: -Inactivated (Killed) Vaccines Examples of inactivated vaccines include: inactivated poliovirus (IPV) vaccine, whole cell pertussis (whooping cough) vaccine, rabies vaccine and the hepatitis A virus vaccine.
