Immunization as a tool to combat antimicrobial resistance

Area of Science:

• Public Health
• Infectious Diseases
• Vaccinology

Background:

• Antimicrobial resistance (AMR) poses a significant global health threat.
• Vaccines are a key strategy to prevent infections caused by AMR pathogens.
• Existing vaccines like pneumococcal and Haemophilus influenzae type b have shown efficacy in reducing AMR.

Purpose of the Study:

• To highlight the role of vaccines in addressing the challenge of antimicrobial resistance.
• To discuss current vaccine development pipelines targeting high-priority AMR pathogens.
• To explore how vaccines can prevent both primary infections and secondary opportunistic infections.

Main Methods:

• Review of existing literature on vaccines and their impact on AMR.
• Identification of high-priority AMR pathogens targeted by vaccine development.
• Analysis of indirect benefits of vaccination, such as preventing secondary infections.

Main Results:

• Vaccines can reduce the prevalence of AMR microbes.
• Vaccination prevents infections and secondary opportunistic infections, thereby mitigating AMR spread.
• Vaccine development is ongoing for critical AMR pathogens like *Clostridium difficile*, *Staphylococcus aureus*, *Streptococcus pneumoniae*, *Mycobacterium tuberculosis*, and *Neisseria gonorrhoeae*.

Conclusions:

• Vaccines are a vital tool in the fight against antimicrobial resistance.
• Preventing infections through vaccination reduces the reliance on antibiotics, slowing AMR.
• Addressing vaccine hesitancy through public health education is essential for achieving herd immunity and maximizing vaccine effectiveness.
