Highlighting Hounds – Chloe Callahan

Welcome back, Hounds! To jumpstart the new year, we are highlighting Chloe Callahan ’24 and her summer internship at Pfizer! As the Global, Emerging Markets Business Analyst, Chloe grew and applied her knowledge as an Economics and International Business double major to the pharmaceutical industry. Read the interview below to learn more about Chloe’s internship at Pfizer.


Why did you apply for an internship at Pfizer?

I have always wanted to work in pharmaceuticals, and Pfizer is a household name.

I heard about this internship last summer when I interned at Pfizer in quality assurance. My role was to update drug product information to global documentation so that other Pfizer branches across the world know what products and substances are being used in the United States. This was an interesting position as I was able to work on the COVID-19 booster batch reports.

I knew I wanted to return to Pfizer because I love their culture. I enjoy the comradery among the employees, and I align myself with their mission to make the world a healthier place.

Describe a typical day as an intern. What were your tasks and responsibilities?

As an Analyst, I research upcoming markets and forecast whether a new drug may be successful in these markets. I communicate with country leads, run statistical analyses, and consider markets’ past data to determine if they can sustain the introduction of a new drug. This included brushing up on my coding and Tableau skills, as well as the ability to communicate with individuals in different countries.

Describe any major projects or accomplishments that you were involved in.

I worked on supplying the Respiratory Syncytial Virus (RSV) vaccine to Latin American countries to fight respiratory tract disease (LRTD) in infants. Argentina will be receiving the first shipment of the vaccine at the end of the quarter.

What are your career goals? How will this internship help you reach those goals?

I hope to get a Master’s in Pharmaceutical Economics and pursue a position in pharmaceuticals long-term. This internship solidified my desire to help developing countries receive the medication that they need.

What advice would you give to a student who wants to participate in an internship?

I recommend networking with people and alumni in the company to gain their advice before applying for an internship.
