Influenza Vaccine Effectiveness and Progress Towards a Universal Influenza Vaccine.
At various times in recent decades, surges have occurred in optimism about the potential for universal influenza vaccines that provide strong, broad, and long-lasting protection and could substantially reduce the disease burden associated with seasonal influenza epidemics as well as the threat posed by pandemic influenza. Each year more than 500 million doses of seasonal influenza vaccine are administered around the world, with most doses being egg-grown inactivated subunit or split-virion vaccines. These vaccines tend to have moderate effectiveness against medically attended influenza for influenza A(H1N1) and influenza B, and somewhat lower for influenza A(H3N2) where differences between vaccine strains and circulating strains can occur more frequently due to antigenic drift and egg adaptations in the vaccine strains. Several enhanced influenza vaccine platforms have been developed including cell-grown antigen, the inclusion of adjuvants, or higher antigen doses, to improve immunogenicity and protection. During the COVID-19 pandemic there was unprecedented speed in development and roll-out of relatively new vaccine platforms, including mRNA vaccines and viral vector vaccines. These new platforms present opportunities to improve protection for influenza beyond existing products. Other approaches continue to be explored. Incremental improvements in influenza vaccine performance should be achievable in the short to medium term.
期刊介绍:
Drugs is a journal that aims to enhance pharmacotherapy by publishing review and original research articles on key aspects of clinical pharmacology and therapeutics. The journal includes:
Leading/current opinion articles providing an overview of contentious or emerging issues.
Definitive reviews of drugs and drug classes, and their place in disease management.
Therapy in Practice articles including recommendations for specific clinical situations.
High-quality, well designed, original clinical research.
Adis Drug Evaluations reviewing the properties and place in therapy of both newer and established drugs.
AdisInsight Reports summarising development at first global approval.
Moreover, the journal offers additional digital features such as animated abstracts, video abstracts, instructional videos, and podcasts to increase visibility and educational value. Plain language summaries accompany articles to assist readers with some knowledge of the field in understanding important medical advances.
