Hint: Vaccine is the process of introducing antibodies to provide resistance to any disease. It provides two types of immunity namely, active immunity and passive immunity. Certain diseases have no vaccines at all. Out of them, some diseases are fatal while others are mild. If the disease turns out to be fatal, the patient either dies or suffers his/her entire life.

Complete answer:
Let’s discuss the options and find the correct answer.
-The two kinds of vaccine for polio are available. The first vaccine is an inactivated polio vaccine (IPV) pioneered by Dr. Jonas Salk and first made use in 1955. The second vaccine is the weakened oral polio vaccine (OPV) which was developed by Dr. Alber Sabin and its first use was made in 1961.
-DPT is a vaccine against three infectious diseases namely, Diphtheria, Pertussis and Tetanus. There are two polio vaccines used throughout the world to fight against poliomyelitis. BCG is a vaccine used to prevent tuberculosis disease. Malaria is a protozoan disease and has no vaccine yet.
-There are 4 vaccines which provide protection against diphtheria. The DTaP vaccine prevents the young children from getting infected from diphtheria, whooping cough and tetanus. The DT vaccine prevents the young children from getting infected from diphtheria and tetanus. The Tdap vaccine helps to protect preteens, teens and adults against tetanus, diphtheria and whooping cough. The Td vaccine helps to build antibodies in preteens, teens and adults against tetanus and diphtheria.
-The vaccine for tuberculosis is Bacillus Calmette-Guerin (BCG) is a vaccine which is readily available for use. It provides protection against severe forms of disease including extrapulmonary disease and the most fatal TB meningitis. It also prevents leprosy.
Hence, option B: Malaria is the correct answer.

Note: There have been a lot of attempts to develop vaccines for malaria but in vain. About 20 other vaccines are under progress for malaria in the past 10 years. There is no licensed vaccine for malaria.
