Vaccines against antimicrobial resistance: a promising escape route for multidrug resistance

Antibiotic resistance has become a global health problem requiring urgent intervention. The pace of development and frequency of transmission of antimicrobial resistance have tremendously surpassed the number of antibiotics developed in the past few decades. Emergence and transmission of multidrug-resistant genes, for example, mcr-1 and mcr-5.3, against the last resort of antibiotics has challenged the treatment options. Vaccination is a promising approach with no instance of antimicrobial resistance generation or transmission reported so far. The time required for developing a vaccine, extensive pre- and post-licensure studies and the financial constraints for the R&D has hampered vaccine development over the past few decades. Vaccine can prove to be an effective future strategy for combating antimicrobial resistance.
