Effectiveness of seasonal influenza vaccines varies greatly during the different flu seasons. Although the WHO assesses and updates influenza vaccine strains every year, the effectiveness of vaccine is sometimes not good. This review explores the various factors that influencing influenza vaccine effects in order to improve the effectiveness of influenza vaccines and provide a scientific basis for influenza vaccination. The results reveal that the degree of matching between epidemic strains and vaccine strains, pre-exposure (natural infection, vaccination), age, and immune status could all affect the vaccine effectiveness.

UI	MeSH Term	Description	Entries
D007251	Influenza, Human	An acute viral infection in humans involving the respiratory tract. It is marked by inflammation of the NASAL MUCOSA; the PHARYNX; and conjunctiva, and by headache and severe, often generalized, myalgia.

D007252	Influenza Vaccines	Vaccines used to prevent infection by viruses in the family ORTHOMYXOVIRIDAE. It includes both killed and attenuated vaccines. The composition of the vaccines is changed each year in response to antigenic shifts and changes in prevalence of influenza virus strains. The flu vaccines may be mono- or multi-valent, which contains one or more ALPHAINFLUENZAVIRUS and BETAINFLUENZAVIRUS strains.
