B/Yamagata lineage

The B/Yamagata lineage refers to a specific strain of the influenza B virus, which is responsible for seasonal flu outbreaks. Influenza viruses are categorized into two main types: A and B, with B further divided into two lineages: Yamagata and Victoria. The Yamagata lineage tends to circulate in the population and is one of the targets for flu vaccines. Tracking these lineages helps scientists and health organizations monitor flu trends and develop effective vaccines to combat flu seasons and outbreaks. Understanding this lineage is important for public health and pandemic preparedness.
