Within the Tuberculosis Vaccine Treatment segmentation by type, five principal vaccine platforms are recognised: live‑attenuated, inactivated, subunit, viral‑vector, and DNA‑based vaccines. Live‑attenuated vaccines, such as BCG derivatives, retain the largest share of the preventive market because of their long‑standing safety profile and low production cost, yet they face regulatory scrutiny for efficacy improvements. Inactivated vaccines contribute a modest share, primarily in niche therapeutic applications where safety is paramount. Subunit vaccines—protein or peptide‑based—are gaining traction in both preventive and therapeutic pipelines due to their ability to target specific antigens and simplify manufacturing. Viral‑vector platforms, exemplified by adenovirus or MVA carriers, are positioned in late‑stage therapeutic trials, offering robust cellular immunity but incurring higher development costs. DNA‑based vaccines, still early in clinical evaluation, promise rapid design cycles and scalable production, potentially reshaping the market as they achieve regulatory approval. Each type’s contribution to market size is proportional to its clinical maturity, pricing power, and adoption by public‑health programmes.
