Influenza season has begun earlier than usual this year, with nearly 5,000 lab-confirmed hospitalizations reported nationwide during the week ending October 17. This represents the highest early-season hospitalization rate for mid-October since the 2010-11 flu season. Health experts recommend that Americans receive their flu shots immediately, regardless of current flu activity levels in their region. Early cases appear to be driven by an H1N1 variant, for which this year’s vaccine provides an incomplete match. However, vaccination can still prevent severe illness and protects against two additional flu viruses expected to circulate later in the season.
People aged 50 and older now have the option of receiving an mRNA flu vaccine, which demonstrated superior performance in clinical trials compared to the standard vaccine. The mRNA approach offers the advantage of faster production, potentially allowing vaccine makers to select virus strains closer to flu season, reducing the time for mutation. Additionally, eligible individuals should consider receiving COVID-19 and RSV vaccines simultaneously with their flu shot, as current vaccines match circulating strains well. Experts also recommend purchasing over-the-counter test kits and identifying local pharmacies that stock prescription antiviral medications, as early treatment is crucial for effectiveness.
