It was hoped that with the invention of the BCG vaccine and medicines, it would be possible to wipe out TB in the same way that smallpox has been eradicated.

- It was hoped that with the invention of the BCG vaccine and medicines, it would be possible to wipe out TB in the same way that smallpox has been eradicated.This has turned out to be difficult because:much of the initial improvement in TB rates in more developed countries was related to improvements in housing, nutrition and access to treatment, but these issues are still present in many countries that are less developed

Answer: 1) Introduction of the BCG vaccine in the mid-nineteenth century.
2) Not taking all the booster doses of the vaccine.
3) Immunocompromised patients.
Explanation: 1) The BCG (Bacille Calmette-Guerin) Vaccine for tuberculosis was introduced in INDIA in the year 1948. Since, this vaccine is mostly taken by a person after birth, many people who take birth before the independence era are not given any vaccines. We can see a lot of aged persons showing cases of TB.
2) Generally due to low immunogenicity of the BCG vaccine, booster doses are given at birth, after 4-6 weeks of age & at after 12-14 weeks of age. Some people are not taking the booster doses of the same resulting in improper or low level of immunogenicity and can develop TB at later.
3) Vaccines like BCG are not given to immunocompromised patients as it can have a negative impact to them.
