A recent study conducted by the World Health Organization (WHO) reveals that immunizations against 24 different pathogens could lead to a 22% reduction in global antibiotic consumption, equating to approximately 2.5 billion defined daily doses each year. This finding bolsters international initiatives aimed at combating antimicrobial resistance (AMR). While several of these vaccines are currently available but not widely utilized, others require urgent development and market introduction.
AMR arises when microorganisms such as bacteria, viruses, fungi, and parasites become resistant to antimicrobial treatments. This resistance complicates treatment options for infections, heightens the risk of severe illness or death, and facilitates the spread of hard-to-treat infections. The primary drivers of AMR include the inappropriate use and over-prescription of antimicrobials; paradoxically, many individuals globally lack access to essential antimicrobial therapies. Annually, nearly 5 million deaths worldwide are linked to AMR.
Vaccines play a crucial role in mitigating AMR by preventing infections altogether. They help decrease both the demand for antimicrobials and their overuse while also hindering the emergence and dissemination of drug-resistant pathogens.
The Impact of Vaccines on Antimicrobial Resistance
This new report builds upon a previous WHO study published in BMJ Global Health last year. It estimates that existing vaccines targeting pneumococcal pneumonia, Haemophilus influenzae type B (Hib), which causes pneumonia and meningitis, as well as typhoid fever could prevent up to 106,000 deaths related to AMR each year. Furthermore, if new vaccines for tuberculosis (TB) and Klebsiella pneumoniae are developed and distributed globally, an additional 543,000 lives could be saved annually from AMR-related complications.
“Tackling antimicrobial resistance begins with infection prevention; vaccines are among our most effective tools,” stated Dr Tedros Adhanom Ghebreyesus, Director-General of WHO. “Prevention is preferable to treatment; thus enhancing access to current vaccines while developing new ones for critical diseases like tuberculosis is vital for saving lives and reversing trends in AMR.”
The Role of Vaccination in Infection Prevention
Individuals who receive vaccinations experience fewer infections overall and have reduced risks associated with secondary infections that may necessitate antibiotic treatments or hospitalization. The report evaluates both licensed vaccines currently available as well as those still under development.
- Streptococcus pneumoniae: If vaccination efforts meet the Immunization Agenda 2030 goal—vaccinating 90% of children worldwide along with older adults—this vaccine alone could save around 33 million antibiotic doses annually.
- Typhoid fever: Accelerating vaccine deployment in high-burden regions could result in savings exceeding 45 million antibiotic doses each year.
- Malaria caused by Plasmodium falciparum: Upwards of 25 million unnecessary antibiotic doses might be avoided since antibiotics are often misapplied during malaria treatment attempts.
- Tuberculosis:If successfully developed soon enough,
- This vaccine has potential savings ranging from approximately 1.2 billion up to nearly two billion antibiotic doses—a significant fraction considering that about 11.3 billion total doses are used annually against diseases discussed within this report.
The Economic Implications: Reducing Costs Associated with Antimicrobial Resistance
The financial burden associated with treating resistant pathogens globally amounts to an estimated US$730 billion per annum according to this report’s findings. Implementing widespread vaccination against all evaluated pathogens has the potential to cut hospital costs related directly or indirectly due to AMR by one-third.
A comprehensive approach centered on people is essential across health systems for effectively preventing infection while diagnosing it accurately when it occurs alongside appropriate treatments being administered promptly thereafter.This strategy recognizes vaccination’s pivotal role within broader efforts aimed at curbing AMR—especially when combined synergistically alongside other interventions designed specifically towards achieving similar goals!
