Is there any mention of the strain that this years vaccine is targeting?
Well.... Type "A" is the one that put me in the hospital for 6 days here in Southern Ohio.. Wow, I really thought I was a goner... Mid 70's, bad lungs, I consider my self lucky... THANK YOU LORD...!!
Typically, it would cover one of the H3N2 and one of the H1N1 variants, along with one or two of the influenza B strains, depending on if it is a trivalent or a quadrivalent vaccine. I do not know specifically which influenza variants are included this year, but I can find out for you if you want.
I used to brief people on which flu vaccine strains were selected each year.

Follow that link and scroll down to “What viruses will the 2017-2018 flu vaccines protect against?”
The following is a quote.
========Quote===============
There are many different flu viruses and they are constantly changing. The composition of U.S. flu vaccines is reviewed annually and updated as needed to match circulating flu viruses. Flu vaccines protect against the three or four viruses (depending on vaccine) that research suggests will be most common. For 2017-2018, three-component vaccines are recommended to contain:
an A/Michigan/45/2015 (H1N1)pdm09-like virus (updated)
an A/Hong Kong/4801/2014 (H3N2)-like virus
a B/Brisbane/60/2008-like (B/Victoria lineage) virus
Quadrivalent (four-component) vaccines, which protect against a second lineage of B viruses, are recommended to be produced using the same viruses recommended for the trivalent vaccines, as well as a B/Phuket/3073/2013-like (B/Yamagata lineage) virus.

At least some of the Walmart stores are administering the Fluzone quadrivalent (four component) for just under $40.
