Vaccination strains match circulating flu strains for 2025-2026

The World Health Organization (WHO) has announced the composition of the influenza vaccine for the upcoming 2025-2026 flu season in the northern hemisphere. This decision comes months in advance to allow manufacturers enough time to produce the vaccines. In the Delhi-NCR region, recent reports indicated a surge in flu cases, with some claiming a spike of over 54%. However, this estimate came from a local survey and not confirmed clinical tests. The National Centre for Disease Control (NCDC) reported 516 flu cases and six deaths in January 2025, yet it remains unclear how this compares to data from previous years. Influenza typically peaks during the monsoon and winter seasons in India. A study showed influenza is responsible for a significant number of illnesses and deaths annually. However, estimating flu deaths is complicated due to the lack of routine testing and certification. The WHO highlighted that, this season, the vaccine strains are expected to match the circulating strains. Dr. Rajeev Dhere from the Serum Institute confirmed there is no mismatch reported this time. Vaccination rates in India have historically been low, especially among vulnerable groups like children and the elderly, despite past outbreaks. Currently, the influenza vaccine is not part of India's universal immunization program. It is recommended for healthcare workers, pregnant women, and those with chronic illnesses, but only deemed desirable for those aged over 65 and children under five. A recent study found only 1.5% of adults over 45 have been vaccinated. Despite low vaccination uptake, there has been a growth in the flu vaccine market in India, with a reported increase of 21% from 2024 to 2025. The Serum Institute can produce between 300,000 to 400,000 vaccine doses, potentially increasing to meet demand.
