Influenza vaccination significantly reduces flu-related morbidity and mortality across all age groups, according to a large-scale Spanish study analyzing data from more than 38 countries and 6.5 million patients. ... The analysis confirms that vaccination against the influenza A (H1N1) virus and the influenza B virus (IBV) effectively reduces infection rates and flu-related complications in children aged under 5 years, individuals aged 5-65 years, and older adults aged over 65 years. However, protection against influenza A (H3N2) virus appears lower in older adults, despite being effective in younger children.
