Beijing Sinovac Biotech Co., Ltd. announced that the expanded age indication for its trivalent influenza vaccine An'er Lifu® (0.5ml/dose) has recently been approved by the National Medical Products Administration (NMPA). With this approval, the target population has been broadened to include children from 6 to 35 months old, making the vaccine suitable for all individuals aged 6 months and above.
Reported as China's first preservative-free trivalent influenza vaccine since its 2006 launch, An'er Lifu® serves a critical population. Children aged 6-35 months face high risks of flu complications, making vaccination the most effective and affordable prevention method. Following expanded age approvals for both Sinovac's quadrivalent and trivalent flu vaccines (0.5ml/dose), the company has now standardized its seasonal vaccine dosages for everyone aged 6 months and above. This milestone will ensure immunization protection for all eligible groups including young children, significantly improving influenza vaccine accessibility across China.
In terms of virus subtypes, influenza A(H3N2) has been the predominant strain detected in China since the start of the 2025-2026 flu season. Experts have strongly advised proactively promoting influenza vaccination, with a focus on covering key high-risk groups such as students, the elderly, and individuals with chronic diseases, to reduce the risk of influenza infection and decrease associated severe cases and fatalities.
Not only in China, but Sinovac's influenza vaccines are also contributing to global influenza prevention and control. In Chile, all influenza vaccines for the government's 2025 national immunization program have been supplied by Sinovac. Since the nationwide vaccination campaign was launched in March, over 7.8 million people in the country have been vaccinated with Sinovac's influenza vaccine. To date, Sinovac's seasonal influenza vaccines have been administered more than 100 million times across nearly 20 countries and regions worldwide.
