Nevertheless,
Vaccination made it possible reduce:
Emergency vaccination during disease epidemics such as cholera. For example, Ebola and measles has reduced the number of deaths due to these pathologies over the past 25 years, demonstrates a new study.
A similar number of infections has been avoided. Meanwhile, and the economic benefits linked to vaccination are estimated at billions of euros, according to this study published this week in the British Medical Journal (BMJ) Global Health.
The study is supported by Gavi. In addition, the alliance of the vaccine, an international organization which, based on public and private funding, helps to vaccinate children in the poorest countries in the world.
The organization has collaborated with researchers from the Burnet Institute. Therefore, in Australia, to produce this first overview of the impact of emergency vaccination efforts on public health and global health security.
“For the first time. we are able to exhaustively vaccination made it possible reduce quantify the advantages, in human and economic terms, of the deployment of vaccines against epidemics of some of the deadliest infectious diseases,” welcomed Sania Nishtar, the Gavi chef, in a press release.
“This study clearly demonstrates the power of vaccines as a profitable response to the growing risk of epidemics with which the world is confronted. ” she added.
The study examined 210 epidemics of five infectious diseases (cholera. ebola, measles, meningitis and yellow fever) in 49 low -income countries between 2000 and 2023.
It shows that the deployment of vaccines under these conditions has reduced the number of infections. deaths by almost 60 % for the five diseases.
And the effect is even more spectacular for certain pathologies. Vaccination made it possible to reduce the number of deaths by 99 % during yellow fever epidemics. 76 % the number of deaths due to Ebola.
At the same time, emergency vaccination has made it vaccination made it possible reduce possible to considerably reduce the risk that an epidemic will extend.
The study also estimates that vaccination efforts made during the 210 epidemics generated around 27 billion euros in economic profits. avoiding deaths and disabilities.
This amount is probably underestimated. points out the report, because it does not take into account the costs of response to epidemics, nor the social and macroeconomic impacts of the disturbances caused by large epidemics.
For example. it is estimated that the massive epidemic of Ebola which struck West Africa in 2014, before the existence of validated vaccines, then saw cases appearing worldwide, cost more than 45 billion euros in West African countries only.
This study comes after the World Health Organization (WHO) warned in April that epidemics of vaccination. such as measles, meningitis and yellow fever, were increasing worldwide due to disinformation and reduction of international aid.
Gavi strives to consolidate new funding in the face of reductions in vaccination made it possible reduce international aid. Washington announced last month that he would stop supporting the group.
