Europe – The European Centre for Disease Prevention and Control (ECDC) has stressed the urgent need to get vaccinated against influenza this year. This comes after the center detected the virus spreading three to four weeks earlier than in the previous two seasons.
This early emergence raises concerns about the impact of the upcoming season on public health and the strain it places on healthcare systems in Europe.
Early emergence raises concerns and identifies a new strain
The European Centre for Disease Prevention and Control (ECDC), in a health threat assessment published on November 20, reported that seasonal influenza has begun circulating earlier than expected. Preliminary data indicate that the new KA(H3N2) subtype is responsible for the majority of detected cases. This increases the urgency of the situation.
In a statement, Eduardo Colzani, head of the respiratory viruses unit at the center, said: “We are seeing an increase in cases of influenza being detected much earlier than usual. This means that time is of the essence. If you are eligible for vaccination, don’t wait. Getting vaccinated now is one of the most effective ways to protect yourself and those around you this winter.”
Health experts warn that this earlier start to the season could be accompanied by a more severe wave. This is especially true if vaccination coverage remains below the required levels.
Worrying scenarios and fears of pressure on healthcare
While the full picture of the 2025–2026 influenza season remains unclear, initial estimates suggest a higher-than-usual number of cases. The European Centre for Disease Prevention and Control (ECDC) fears that this increase, coupled with a potential decrease in vaccination rates, will place increasing pressure on healthcare systems. These systems have already begun preparing for various scenarios.
European Centre Recommendations: No delay in vaccination
The European Centre emphasizes that vaccination is the first and most effective line of defense against influenza. It specifically urges those most at risk to get vaccinated without delay:
People over 65 years of age.
Pregnant women.
Those suffering from chronic illnesses or underlying conditions.
Individuals with weakened immune systems.
Residents and staff in long-term care facilities.
Healthcare workers.
The center also urges healthcare institutions to strengthen their preparedness plans and implement infection prevention and control measures. This includes encouraging the use of masks during peak respiratory virus outbreaks.
Outlook: Moving early is key
With the emergence of the KA(H3N2) strain and the early spread of influenza this year, health officials agree that early action is key to mitigating any potential surge. The ECDC’s most prominent warning remains clear and firm: “Don’t wait… get vaccinated now.”
