Vaccines for Neglected Tropical Diseases
The mRNA platform is also being leveraged for vaccines against neglected tropical diseases such as malaria and tuberculosis, offering the potential for rapid development and scalable production. This represents an agile response system, capable of addressing diverse and urgent global health needs.
Combating Antimicrobial Resistance (AMR)
The growing threat of AMR demands novel approaches to antibiotic development.
New Classes of Antibiotics
Discovery efforts are yielding new classes of antibiotics targeting novel bacterial pathways, offering hope against multi-drug resistant pathogens. These new molecules act as keys to entirely new locks, bypassing existing resistance mechanisms.
Phage Therapy Revival
Bacteriophage therapy, though historically used, is experiencing a resurgence. Recent clinical trials are exploring genetically engineered phages to specifically target and lyse antibiotic-resistant bacteria, offering a highly precise and customizable weapon against bacterial infections. This is a return to an older, nature-inspired weapon, now enhanced with modern engineering.
