Multivalent mRNA tuberculosis vaccines (TUmRNA4, TUmRNA6, TUmRNA9) reduce mycobacterial burden and lung pathology in mice and guinea pigs, with TUmRNA6 boosting BCG protection.
- Why it matters: BCG has not been sufficient against tuberculosis, so new vaccine strategies are needed that can generate strong, antigen-specific cellular immunity.
- What they did: Antigens were discovered in zebrafish and encoded into mRNA candidates carrying four, six, or nine Mycobacterium tuberculosis antigens; vaccinated animals were assessed for IFN{gamma} responses, memory T-cell expansion, and organ bacterial burden and lesions.
- The result: In mice, TUmRNA4 and TUmRNA6 lowered pulmonary Mycobacterium tuberculosis burden and lung pathology to levels comparable to BCG, and TUmRNA6 as a booster enhanced BCG-mediated protection; in guinea pigs, TUmRNA9 reduced bacterial burden in lungs, spleen, and lymph nodes and decreased pulmonary lesions.
