Respiratory infections and their long-term effects

Respiratory infections, such as influenza, SARS-CoV-2, RSV, and pneumococcus, are often seen as routine seasonal illnesses, even though they can cause long-term health issues like cardiovascular risk, cognitive decline, and increased antibiotic use in children. These infections also impact the elderly by reducing their autonomy and increasing their risk of respiratory complications.

Low vaccination coverage remains a concern

Despite growing awareness of the long-term risks, vaccination rates remain below recommended levels, especially among adults and seniors. For the 2025-2026 season, influenza vaccination coverage was far from the World Health Organization's 75% target, with only about 55% of seniors and less than 30% of high-risk adults under 65 receiving the vaccine.

Burden of respiratory infections extends beyond health

The impact of respiratory infections goes beyond individual health. They affect caregivers, families, healthcare workers, and the economy, leading to high direct and indirect costs. Studies show that adult immunization programs can yield returns up to 19 times the initial investment when considering all societal and economic benefits.

Tools exist to better protect vulnerable groups

There are effective strategies to protect vulnerable populations, including infants, the elderly, and those with chronic illnesses. However, these strategies only work if they are widely adopted. This requires better public awareness, coordinated efforts among healthcare professionals, easier access to vaccines, and policies that set clear vaccination targets.

A national prevention program is needed

A multi-year national prevention program would help shift focus from managing seasonal outbreaks to long-term prevention. It would identify under-protected groups and adjust strategies accordingly. Respiratory infections are serious and should not be dismissed as routine, given their ongoing impact on individuals and society.
