Health experts are sounding the alarm about a new subtype of the flu virus, warning that it could trigger a severe outbreak this winter. The H3N2 strain, known for its potential severity, has caused flu cases to appear earlier than usual across the UK.
Medical professionals are urging all eligible individuals—including children, older adults, and those with certain health conditions—to get their flu vaccinations without delay. Early vaccination is crucial to building immunity, as the vaccine takes a few weeks to reach full effectiveness.
Recent surveillance data reveals flu activity is rising atypically early, initially affecting teenagers and young adults, then spreading to younger children. Testing shows that 84% of flu cases this season are caused by the H3N2 subtype, prompting particular concern.

Paul Fisher, a consultant in health protection at the UK Health Security Agency’s West Midlands branch, emphasized the urgency: “An early flu season increases the risk of severe illness and hospital admissions. Vaccination remains the best way to protect yourself and vulnerable loved ones.”
He added that many people may not be aware they qualify for a free flu jab, available to pensioners, young children, pregnant women, those with weakened immune systems, and individuals with long-term health conditions.
“This season’s flu vaccine continues to offer important protection despite the emergence of this new viral subtype,” Fisher noted. “Getting vaccinated early not only safeguards your health but also helps prevent flu spreading to others, especially children who are often key transmitters.”
In summary, health officials stress the message: “Stay strong, get vaccinated” to reduce severe flu cases and protect the community during what could be a challenging season.
