The pharmaceutical giant Pfizer agreed to buy AstraZeneca's small molecule antibiotics business in a deal that could be valued at more than $1.5 billion. Pfizer also agreed to buy Medivation for approximately $14 billion earlier this week.Looks like after failed merger with Allergan Pfizer isn't wasting time and is searching for new deals, and honestly smaller ones seem much more viable right now. So I continue keeping Pfizer shares in my portfolio $PFE, Pfizer, Inc. / 1440
