Overview
- Peru’s health ministry has registered six laboratory-confirmed H3N2 infections, all identified as subclade K.
- Specialists characterize subclade K as a seasonal branch that is highly transmissible with no evidence it is more lethal.
- The ministry says updated doses will arrive in early February, roughly two months ahead of the usual southern-hemisphere timeline, enabled by a contract already paid in full.
- Distribution will prioritize older adults, young children and people with underlying conditions, and the shots are distinct from Covid-19 vaccines.
- Regional updates highlight ongoing vaccination efforts and stock, with Sonora reporting about 55% influenza coverage and sufficient inventories, and clinicians noting the October 2025 vaccine still confers protection.
