Main information
- COVVI-19 vaccines saved around 2.5 million lives worldwide during the pandemic.
- The effectiveness of vaccines has varied significantly depending on the age group. Most deaths have been avoided in people aged 60 and over.
- In the future, vaccines should be distributed primarily to high-risk groups, while taking into account the cost-benefit report for other populations.
A recent study by researchers from the University of Stanford and Italy suggests that the number of lives saved by COVVI-19 vaccines could be significantly lower than previous estimates. Previous analyzes, in particular that of the World Health Organization (WHO), provided that vaccines had made it possible to avoid millions of deaths worldwide in the first year.
However, the new modeling indicates a more prudent figure, with an estimate of 2.5 million lives saved worldwide over the whole pandemic. The study highlights a significant difference in the advantages between age groups. Most of the deaths avoided concerned people aged 60 and over. On the other hand, the impact of the vaccine on younger population groups was minimal: only a few hundred lives have been saved worldwide among those under 30.
Priority of vaccination efforts
The researchers expressed their concern about “aggressive mandates” and the pressure exerted to vaccinate everyone, regardless of individual risk factors. They believe that future vaccination campaigns must prioritize high -risk groups. At the same time, they must carefully take into account the cost-benefit report for other populations.
More targeted approach DEST vaccination strategies
The study used data on the world’s population, vaccine efficiency rates and lethality rates of infections to achieve its estimates. Researchers believe that previous models may have overestimated the effectiveness of vaccines. At the same time, they would have underestimated the already existing immunity among the population.
While recognizing the “substantial benefit” of vaccines in reducing world mortality, especially in the elderly. It also highlights the importance of a more targeted approach to vaccination strategies during future pandemics.
According to the researchers, it is necessary to pay more attention to individual risk factors, to potential side effects and to the balance between public health and personal autonomy. The results of the study aroused debate on vaccine obligations and ethical considerations surrounding mass vaccination campaigns. (em)
