On Oct. 10, 2024, a report by the World Health Organization (WHO) found that vaccines against 24 pathogens could reduce the number of antibiotics needed by 22% or 2.5 billion defined daily doses globally every year, supporting worldwide efforts to address antimicrobial resistance (AMR). While some of these vaccines were already available but underused, others would need to be developed and brought to the market as soon as possible.

AMR occurs when bacteria, viruses, fungi, and parasites no longer respond to antimicrobial medicines, making people sicker and increasing the risk of illness, death and the spread of infections that are difficult to treat. Vaccinated people have fewer infections and are protected against potential complications from secondary infections that may need antimicrobial medicines or require admission to hospital.
