Vaccine coverage in the Northern Hemisphere from 2001 to 2017. The X-axis represents years from 2001 to 2017, and the Y-axis represents the antigenic coverage of vaccine strains in each year. Each line refers to a vaccine strain from the year before it was proposed as the vaccine strain to the year after it was replaced by updated vaccine strain. Stars indicate the years in which each vaccine strain was recommended.
