Answer the following questions.
Using the data provided in FluNet, tell me what are the circulating strains in the US as of 2/20/2023? Were there any shifts in influenza variant from fall to winter?
Do a little sleuthing and tell me what variants were included in the flu vaccine administered this past flu season (Fall 2022 – present)
Based on data from February 2023 – does it look like the vaccine is paired well? What does the data tell us about vaccine efficacy this year for influenza? Try to figure it out using the data first, then feel free to look for other sources – but be sure to include citations if you use outside literature
How does the burden of influenza this season compare to the burden of influenza for the 2020-2021 flu season? Use numbers to support your response
