Germany’s Flu Wave Deepens as H3N2 Subclade K Dominates, Forcing Hospital Cutbacks and Vaccine Imports

Emergency imports of high‑dose flu shots underscore vaccine strain during an early wave driven by a faster‑spreading H3N2 offshoot.

Overview

  • RKI data show more than 20,000 lab‑confirmed cases in the week of January 5–11, a season total above 80,000, and 225 deaths largely among people aged 60 and older.
  • Genetic monitoring finds Subclade K now predominant; early lab results indicate somewhat shorter protection against infection, yet vaccines are still expected to reduce severe outcomes.
  • About one third of ICUs report restricted operations, with some hospitals postponing elective procedures to preserve emergency capacity.
  • Pediatric specialists report that most children hospitalized with acute respiratory illness currently have influenza, with admissions rising after the holidays.
  • High‑dose vaccine supplies for older adults are tight, the PEI has authorized Italian‑labeled Efluelda packs for temporary use, and pharmacists caution the peak may align with Carnival celebrations.
