No new H1N1 strain in circulation, current vaccines effective: ICMR officials
ICMR officials said no new H1N1 strain is circulating in India and the current viruses are well matched with vaccines recommended for the Northern Hemisphere.
The Indian Council of Medical Research (ICMR) has stated that the current H1N1 strain circulating in India is not a new variant, and the vaccines recommended for the Northern Hemisphere are effective against it. The strain, identified as A/Missouri/11/2025 (H1N1) pdm09-like virus, has been in circulation since 2025 and is responsible for a recent rise in cases, particularly in Delhi, with nearly 1,800 cases reported this season.
While the mortality rate remains low, high-risk individuals are advised to take extra precautions. Doctors emphasize that seasonal influenza, including H1N1, is self-limiting and usually manageable with rest and appropriate care.
