A. Tuberculosis

Explanation:

  BCG vaccine (Bacillus of Calmette and Guérin) was created in 1921 by Léon Calmette and Alphonse Guérin. Protects against severe forms of tuberculosis, a contagious disease caused by the bacterium Mycobacterium tuberculosis, which mainly affects the lungs and, if untreated, can cause serious breathing problems, weight loss, weakness and even death. The vaccine is the only type of immunization against the disease and should be given as a single dose.

Pentavalent vaccine protects against 5 diseases: diphtheria, tetanus, pertussis, poliovirus and infections caused by Haemophilus influenzae type b (meningitis, pericarditis, pneumonia, arthritis  and osteomyelitis).
