Enhancing the role of vaccines in combatting antimicrobial resistance

Interest in addressing antimicrobial resistance (AMR) has grown recently but little effort has been made to consider how existing and new vaccines could impact on AMR. A 2017 Chatham House meeting considered the role of vaccines and how to demonstrate their value through their impact on AMR. Ways existing vaccines have reduced antibiotic prescribing and the prevalence of some resistant organisms were reviewed. Other new vaccines could have a similar impact. In gonorrhoea, where complete resistance has developed, vaccine may be the best option. Valuing the impact of vaccines on AMR was challenging: there were difficult methodological issues and a lack of data for modelling. A participant poll suggested priorities for accelerated vaccine development were tuberculosis, typhoid, influenza, RSV and gonorrhoea. More evidence is needed to convince policymakers but that vaccine development projects should be considered by funders on the same basis as those for new antibiotics or diagnostics.
