Highlights:

Vaccines against 24 infections might lower the number of antibiotics required globally by 22%, or 2.5 billion specified daily doses per year, suggested an assessment by the World Health Organization (WHO). This could aid global efforts to combat antimicrobial resistance (AMR). While some of these vaccines are currently accessible but underutilized, others must be produced and brought to market as quickly as possible (1).


What is Antimicrobial Resistance (AMR)?

AMR occurs when bacteria, viruses, fungi, and parasites stop responding to antimicrobial drugs, making people sicker and increasing the risk of sickness, mortality, and the spread of difficult-to-treat illnesses.

What are the Causes of Antimicrobial Resistance?

AMR is mostly caused by the misuse and overuse of antibiotics. On the contrary, many people around the world lack access to important antimicrobials. Every year, AMR causes roughly 5 million deaths worldwide.

Role of Vaccines in Preventing Antimicrobial Resistance

Vaccines are an important component of the response to AMR because they prevent infections, minimize antibiotic usage and misuse, and slow the emergence and spread of drug-resistant bacteria.

Vaccines Can Prevent Deaths Due to Antimicrobial Resistance

The latest report builds upon a WHO study published in BMJ Global Health last year (1). It forecasts that vaccines already in use against pneumococcus pneumonia, Haemophilus influenzae type B (Hib, a germ that causes pneumonia and meningitis), and typhoid could prevent up to 106,000 fatalities from AMR each year.

An additional 543 000 deaths from AMR could be avoided each year if new vaccinations for tuberculosis (TB) and Klebsiella pneumoniae are developed and implemented globally. While new tuberculosis vaccines are in clinical trials, one for Klebsiella pneumoniae is in its early stages of research.

Prevent Infections and Combat Antimicrobial Resistance

"Preventing infections is the first step in addressing antimicrobial resistance," stated Dr Tedros Adhanom Ghebreyesus, Director-General of the World Health Organization. "Prevention is better than cure, and increasing access to existing vaccines and developing new ones for critical diseases, like tuberculosis, is critical to saving lives and turning the tide on AMR."

Vaccinated people have fewer illnesses and are less likely to have complications from subsequent infections that may necessitate the use of antimicrobial medications or hospitalization. The paper assessed the impact of both licensed vaccines and vaccines in various stages of development.

How Vaccines Help Prevent Diseases

Every year, vaccinations against:


People-Centered Strategy to Prevent Antimicrobial Resistance

To prevent, detect, and treat infections, a comprehensive, people-centered strategy must be implemented across all health systems. This approach considers vaccination as essential for avoiding AMR and particularly effective when paired with other therapies.

On September 26, the 79th United Nations General Assembly High-Level Meeting on AMR approved a political declaration committing to a clear set of targets and activities, including a 10% reduction in the anticipated 4.95 million human fatalities from bacterial AMR by 2030. The proclamation underlines crucial topics such as the necessity of access to vaccinations, medicines, treatments, and diagnostics, as well as the need for incentives and finance structures to encourage multisectoral health research, innovation, and development in the fight against AMR.
