We conducted a large-scale epidemiologic and evolutionary study of 1,329 E30 strains collected in 22 countries in Europe during 2016-2018. Most E30 cases affected persons 0-4 years of age (29%) and 25-34 years of age (27%).

Its effectiveness depends critically on using the appropriate sample types and high assay sensitivity as viral loads in cerebrospinal fluid samples from meningitis and sepsis clinical presentation can be extremely low. This study evaluated the sensitivity and specificity of currently used commercial and in-house diagnostic and typing assays.

- Influenza A(H3N2) was the dominant strain in Europe during the 2016-17 season, with both A(H3N2) and A(H1N1)pdm09 circulating in the 2017-18 season; the A(H3N2) vaccine component remained unchanged, while A(H1N1) was updated.
- A study across 12 European countries assessed influenza vaccine effectiveness (VE), finding good protection (59% VE) against A(H1N1)pdm09, but low effectiveness (28% for 2016-17 and 13% for 2017-18) against A(H3N2), particularly in older populations.
- The low effectiveness of the
Article Synopsis
- Previous studies on the impact of previous influenza vaccinations on current season vaccine effectiveness (VE) have shown inconsistent results.
- This study analyzed data from multiple seasons to assess the VE among those vaccinated in the previous season compared to those who were not.
- The findings revealed no clear pattern regarding the effects of past vaccinations, highlighting the need for more detailed studies to better understand these relationships.
