In evaluating BCG vaccination, one must first define its potentialities. BCG vaccine, properly administered, will increase the resistance of both animal and man to virulent tubercle bacilli.

Tuberculosis Vaccine Development — Its History and Future Directions

A vaccine is a biological preparation that provides active acquired immunity to a particular infectious disease. The agent stimulates the body's immune system to recognize the agent as a threat, destroy it, and to further recognize and destroy any of the microorganisms associated with that agent that it may encounter in the future. Vaccines can be prophylactic to prevent or ameliorate the effects of a future infection by a natural or "wild" pathogen , or therapeutic to fight a disease that has already occurred, such as cancer. The administration of vaccines is called vaccination. Vaccination is the most effective method of preventing infectious diseases; [6] widespread immunity due to vaccination is largely responsible for the worldwide eradication of smallpox and the restriction of diseases such as polio , measles , and tetanus from much of the world. The effectiveness of vaccination has been widely studied and verified; [7] for example, vaccines that have proven effective include the influenza vaccine , [8] the HPV vaccine , [9] and the chicken pox vaccine. The terms vaccine and vaccination are derived from Variolae vaccinae smallpox of the cow , the term devised by Edward Jenner who both developed the concept of vaccines and created the first vaccine to denote cowpox.

Even though the BCG vaccine is still widely used, results on its effectiveness in preventing mycobacterial diseases are partially contradictory, especially regarding Buruli Ulcer Disease BUD. The present study was performed in three different countries and sites where BUD is endemic: in the Democratic Republic of the Congo, Ghana, and Togo from through The large study population was comprised of cases with laboratory confirmed BUD and controls, mostly family members or neighbors. After stratification by the three countries, two sexes and four age groups, no significant correlation was found between the presence of BCG scar and BUD status of individuals.

To enhance the TS of the vaccine, some prevalent stabilizers in different concentrations were added to the final formulation of BCG bulk prior to Freeze-drying process. We found a formulation more effective than the current stabilizer for retaining the higher viability of lyophilized BCG vaccine produced by Pasteur Institute of Iran. In the design of experiments using Taguchi method, lactose, trehalose, glucose, dextran, and monosodium glutamate were added to the final formulation of BCG bulk prior to freeze-drying process.

Rates of protection against tuberculosis infection vary widely and protection lasts up to twenty years.
