Flu vaccines protect children well across Europe, but H3N2 remains harder to stop

Influenza vaccination provided strong real-world protection for children in European primary care across two seasons, with overall vaccine effectiveness of 68% in 2022–2023 and 71% in 2023–2024. Protection was highest against influenza B and H1N1, while H3N2 showed lower and more variable effectiveness, supporting the need for higher uptake and continued monitoring.

Flu vaccination may cut heart attack and stroke risk after infection

In Danish adults aged 40 years or older, laboratory-confirmed influenza was linked to a sharp short-term rise in first-time heart attack and stroke risk, especially in the first 7 days after infection. Prior same-season influenza vaccination was associated with about half the excess cardiovascular risk among infected individuals, suggesting possible protection even in breakthrough cases.

High-dose flu shots inked to lower Alzheimer's dementia risk in older adults

A large US claims-based study found that adults aged 65 and older who received a high-dose flu vaccine had a lower observed risk of Alzheimer dementia than those who received a standard-dose vaccine, with the association lasting up to 25 months in per-protocol analyses and 28 months in intention-to-treat analyses. The signal appeared stronger and more sustained in women, though the authors stress that the findings are observational and need confirmation in longer prospective studies.
