Some of the locations do not use the pharmaceutical's company name, Sanofil, when discussing the vaccine names. They may say something about offering "Flublok" and "Fluzone," respectively. The two types are manufactured by the company and are for particular age ranges. The pharmacy's I visited were all for the same grocery chain and only two locations showed me the vaccine packaging for both varieties, pointing to the pharmaceutical name on the package, too, Sanofi.
As far as the photographs, there could be all sorts of types of signage in and around the pharmacy. Mine were all generic signs, that simply stated they offered flu shots, etc. Some were on the payment terminal, some were in a plastic holder on a counter, a poster on the bulletin board, a sticker on the counter, in an aisle near the OTC items, etc. So, it was very easy to take two photographs of any or all of those to make sure you got what you needed.
