A new vaccine against the deadly air-borne disease, tuberculosis, could be available in the next eight years. At present, the only available vaccine for the prevention of TB is Bacille-Calmette-Guérin (BCG), which was discovered almost 100 years ago.The World Health Organization (WHO) said that the world is finally waking up to the need for an effective new-age TB vaccine with 11 vaccine candidates for TB prevention in Phase I or Phase II trials and one immunotherapeutic vaccine in a Phase III trial. WHO said, “It is hoped that one or two of the candidates in a Phase II trial will enter a Phase III trial in the next three years, with the possibility of licensing at least one new vaccine by 2020.
A new vaccine that prevents TB could significantly reduce the enormous financial burden of treating drug-resistant TB – which can cost Rs 1 lakh per patient in India. India is home to about 73,000 drug-resistant TB patients.
1.6% of resistant TB patients enrolled In a shocking disclosure, WHO has said that while India is home to 73,000 patients with multi-drug resistant TB, the health ministry notified just 2% of these cases as being resistant to drugs. Barely 1.6% of these MDR TB patients were enrolled for treatment.TB one of top killers of women After almost 100 years, there are hopes of a new tuberculosis vaccine. This could prevent the toll that the disease takes on individuals who are subjected to 18-24 months of medication with side effects that can be as severe as hearing loss or psychosis. In 2011, there were an estimated 8.7 million new cases of TB (13% co-infected with HIV) and 1.4 million people died from the disease, including almost one million deaths among HIV-negative individuals and 4.3 lakh among people who were HIV-positive. TB is one of the top killers of women, with 3 lakh deaths among HIV-negative women and 2 lakh mortalities among HIV-positive women last year.
