Recent research underscores a crucial point: vaccinations significantly lower the rates of hospitalizations due to both flu and COVID-19.
This analysis not only highlights the effectiveness of vaccines but also reveals significant disparities in vaccination rates across different countries, implying that there is substantial room for improvement when it comes to alleviating the burden on healthcare systems.
While vaccines have been shown to effectively prevent severe illness, the uptake of influenza vaccinations in many EU/EEA nations remains alarmingly below the targets set by the World Health Organization (WHO) for vulnerable populations. Additionally, the rates of COVID-19 vaccinations are continuing to decline—a trend that raises concerns.
In order to conduct this analysis, RespiCompass collaborated with various international modeling teams, integrating their models to explore a range of scenarios. The collective results from these modeling efforts complement existing clinical studies on vaccine effectiveness and provide valuable insights for national public health agencies, vaccination program managers, healthcare professionals, and science communicators. This information can be instrumental in enhancing future vaccination strategies.
Moreover, studies like this one foster collaboration on cost-effectiveness research, resource allocation, and improved public health messaging at both the EU/EEA level and within individual nations.
Key insights from the study indicate that between August 5, 2024, and June 1, 2025, vaccination programs in EU/EEA countries are expected to:
- Prevent between 26% and 41% of flu-related hospitalizations among adults aged 65 and older;
- Decrease COVID-19 hospitalizations in the same age group by 14% to 20%.
These projections are based on an assumed vaccine effectiveness of 60% for influenza vaccines and 75% for COVID-19 vaccines, reflecting the most recent data available. The variation in the estimated reduction of hospitalizations stems from differing levels of vaccine uptake as well as assumptions about the transmissibility of the viruses and the duration of immunity.
The findings from this research reveal untapped potential to alleviate pressure on hospitals through established practices like seasonal flu vaccinations, alongside newer initiatives such as COVID-19 vaccination campaigns. Importantly, they emphasize that even modest increases in vaccine uptake can lead to significant declines in hospitalization rates.
But here's where it gets controversial: why are vaccination rates still lagging? What factors contribute to this persistent gap? We invite you to share your thoughts and engage in a conversation—do you think more aggressive public health campaigns could change this trajectory? Or is there something deeper at play in vaccine hesitancy?
