Antimicrobial Resistance and Immunisation
A POSTnote that describes the potential for immunisation as a strategy to tackle antimicrobial resistance, both globally and in the UK. It discusses public health priority areas, the role for existing vaccines and the development of new ones.
Antimicrobial resistance (AMR) is an urgent global health threat that, if left unchecked, could account for an estimated 10 million deaths per year by 2050. A report commissioned by the UK Government and published in 2016 concluded that vaccines have been overlooked as a tool to reduce AMR and should be an investment focus.
Immunisation can reduce the AMR burden by preventing infections (including resistant ones) and therefore reducing antibiotic use, a major driver of resistance. This effect has already been seen for vaccines against pneumococcal and influenza infections. There are global differences in vaccine need and the challenges in using immunisation to reduce AMR.
There are two main approaches to this strategy: maximising the utility of existing vaccines by ensuring good uptake and offering them more widely as appropriate, and making decisions about which vaccines should be developed and introduced and when and where to use them most efficiently. Evaluating the impact and cost-effectiveness of a vaccine is an essential step in its use and introduction but how to value a vaccine in the context of AMR is complex and subject to ongoing research.
- Antimicrobial resistance (AMR) has reached a point where some infections may become untreatable.
- Immunisation is one strategy to tackle AMR, by decreasing rates of infection and thereby antibiotic use and preventing the development of resistant infections.
- The World Health Organization has developed a list of pathogens where AMR is of most concern and new antibiotics are needed; there is no equivalent for vaccines.
- Quantifying the impact of immunisation on AMR and incorporating this into calculating the cost-effectiveness of vaccines is still an area of ongoing research.
- Using immunisation to tackle AMR depends on wider use and increased uptake of existing vaccines, and increasing the development of new ones.
