- Serotyping data were available for 60% of cases. Among cases with known serotype, non-capsulated strains continued to dominate, accounting for 81% of infections. Serotype f was the most frequent capsulated strain, responsible for 6% (194 cases) of all cases, followed by serotype b 5% (164 cases)
- In 2023, serotype b (Hib) represented 5% of known serotyped cases, reflecting a slight decline from 9.1% in 2022. The low proportion of serotype b (Hib) reported continues to reflect the strong effect of the Hib vaccination programmes in EU/EEA countries.
