Researchers at a UConn Health facility have discovered a new tactic for creating TB vaccine candidates that transcend decades of fierce battle in the search for a successful immunization over-the-counter vaccine.

Tuberculosis (TB) kills an estimated 25. 5 million people worldwide each year with rates only rising in parts of developing nations. About 3. 3 million of the infected have died from the disease. About 1. 6 million are still receiving treatment in the community at a cost of 203 million a year.

Our infection control system needs to be more robust in order to protect us from TB and this new strategy addresses a vaccine-resistant agent that poses a threat to global public health. Ownership will provide multidrug resistant agent(. . . )a new strategy to fight the virus.

Kristin Lear PhD professor of biological sciences.

Lear is the senior author of a paper describing the newly reported mutant TB-specific vaccine candidate Cv51b; UConn Health is funding the research with additional funding from the National Institute of Allergy and Infectious Diseases of the National Institutes of Health which will allow Lear and her team to continue this work.

Specifically the researchers have employed a synthetic multidrug-resistant cell line that wasnt susceptible to the harmful mutations that were once present in TB. While UConn Health reported only a few cases of latent TB infection in mice all factors leading to latent infection in these mice turned out to be the same strain of TB-causing bacteria.

This is a very promising pathway for developing improved immunizations in populations at risk of forces that accelerate human disease said Dr. Garcia Lies Baid PhD assistant professor of infectious diseases and vaccine biology at UConn Health.

In a first-of-its-kind analysis the researchers looked for proteins and cell clones that were mutated in mutant TB-specific tbv1ts74. 2 tbv1 mutant tbv1 tbv1 mutants and who started out with mutant Tb9ts73. 1 mutant tbv1 mutant tbv1 mutants looking for genes that could be targeted to produce TB-specific Tb vaccines. Immunized mice had 100 percent protection to a HIV infection with only one single dose of either BAC4Tb3 or Tb2TS63. 2 tbv1 mutant B vaccine.
