Use standard and enhanced vaccines to prevent influenza, while new classes remain in development
摘要
Routine annual vaccination remains the most effective way to prevent infection caused by the influenza virus. Inactivated egg-based vaccines are the established standard. Recent development including cell-based, high dose, adjuvanted, and recombinant vaccines has provided incremental improvements in vaccine efficacy. Live-attenuated vaccines may have advantages, although are not recommended for high-risk patients. Further vaccine technologies are in clinical development, including vaccine platforms used during the COVID-19 pandemic. New research is required to accurately predict real-world efficacy of enhanced vaccines that activate non-haemagglutinin immune responses.
