Vaccinations will prevent 69 million deaths by 2030

19 March 2021

A modelling study has estimated that vaccination against 10 major pathogens will have prevented 69 million deaths in low-income and middle-income countries (LMICs) over the period 2000 to 2030.

The study, published in The Lancet, also estimated that from 2000 to 2019, vaccinations prevented 37 million deaths – a 45% reduction in the number of deaths had there been no vaccines.

Most of this lower mortality impact was estimated to have been among children under five years old.

The research also forecast that those born in 2019 will experience 72% lower mortality from the 10 diseases over their lifetime thanks to vaccine programmes.

The 10 pathogens vaccinated against in the study included hepatitis B, Japanese encephalitis, measles and rubella.

Co-author Dr Caroline Trotter said: ‘Our modelling has [...] indicated what might be lost if current vaccination programmes are not sustained.’
