Haha, you're fine. 

Physics is a term to describe "Physical Science", which is just the study of our universe. Of course this is an incredibly broad spectrum. This is why the study of it can encompass many different fields. I do believe Pfizer is a pharma company but a physicist wouldn't work with bacteria. That would be saved for those with microbiology or molecular biology degrees. I saw a job posting for Pfizer a little bit ago that required a mathematics or physics degree but the specifics escape me. Probably more in a support and data capacity. One of the main areas people go into with a physics degree is engineering.
