Abstract:
Antibiotics have dramatically reduced the burden of infectious diseases since their discovery, but the accelerating rise in antimicrobial resistance (AMR) now threatens these gains. AMR was responsible for nearly 5 million deaths in 2023 and continues to undermine the efficacy of existing treatments, particularly in low- and middle-income countries. While efforts to address AMR have focused heavily on antibiotic stewardship and new drug development, vaccines represent a powerful yet underutilized tool for prevention. By reducing the incidence of bacterial infections, vaccines lower antibiotic consumption, interrupt transmission of resistant strains, and minimize the selective pressures that drive resistance. Unlike antibiotics, vaccines offer long-lasting protection, rarely induce resistance, and confer indirect protection through herd immunity. This review examines the global burden and drivers of AMR, highlights the unique advantages of vaccines over antibiotics in mitigating AMR, and surveys the current development pipeline of vaccines targeting key multidrug-resistant bacterial pathogens.
Insights
Antimicrobial resistance (AMR) is a growing threat, causing millions of deaths annually. Vaccines offer a powerful preventive strategy against bacterial infections, reducing antibiotic use and slowing the spread of resistant strains.
Area of Science:
- Microbiology
- Epidemiology
- Vaccinology
Background:
- Antimicrobial resistance (AMR) poses a significant global health threat, undermining modern medicine.
- AMR caused nearly 5 million deaths in 2023, with a disproportionate impact on low- and middle-income countries.
- Current AMR mitigation strategies primarily focus on antibiotic stewardship and novel drug development.
Purpose of the Study:
- To review the global burden and drivers of AMR.
- To highlight the advantages of vaccines as a tool to combat AMR.
- To survey the vaccine development pipeline for key multidrug-resistant pathogens.
Main Methods:
- Literature review of global AMR data and trends.
- Analysis of vaccine mechanisms and epidemiological impact on AMR.
- Survey of ongoing vaccine research and development for resistant bacterial pathogens.
Main Results:
- Vaccines reduce bacterial infection incidence, thereby decreasing antibiotic consumption.
- Vaccination interrupts the transmission of resistant bacterial strains.
- Vaccines offer long-term protection and herd immunity, unlike antibiotics.
Conclusions:
- Vaccines are an underutilized but critical component in the fight against AMR.
- Preventive strategies like vaccination complement antibiotic stewardship and new drug development.
- Further investment in vaccine development is crucial to address the AMR crisis.

Phagocytes
Phagocytes are the frontline soldiers of the immune system. They include neutrophils and macrophages. Neutrophils are the most abundant type of white blood cell and are quickly mobilized to the site of infection. Macrophages are larger cells that patrol...
