Job description

Job Description

The Future Talent Program features internships that last up to 12 weeks and will include one or more projects. These opportunities in our Research and Development Division can provide you with great development and a chance to see if we are the right company for your long-term goals.

Position Description

The Exploratory Vaccines-Regulated Bioanalytics group supports vaccine research and development by designing and implementing innovative immunological assays used to characterize vaccine‑induced immune responses. We develop and apply functional bioanalytical platforms that help advance vaccine candidates from discovery through clinical development.

The successful candidate will contribute to the development of a novel multiplex antibody‑dependent cellular phagocytosis (ADCP) assay designed to simultaneously evaluate functional antibody responses against multiple respiratory vaccine antigens. This internship offers a unique opportunity to gain hands‑on experience in immunology assay development, flow cytometry, vaccine bioanalytic, and data analysis while working alongside scientists supporting cutting‑edge vaccine programs.

Project Overview

Antibody‑dependent cellular phagocytosis (ADCP) is an important antibody effector function that contributes to vaccine‑induced immunity. Current ADCP testing is performed in a singleplex format, requiring independent analysis of each vaccine antigen. The goal of this project is to establish a bead‑based multiplex ADCP platform capable of simultaneously measuring functional antibody responses against multiple antigens.

The intern will perform proof‑of‑concept studies to evaluate multiplex assay feasibility, optimize assay conditions, generate and analyze experimental data, and compare multiplex assay performance to established singleplex methods. This work has the potential to improve assay throughput, reduce sample and reagent consumption, and expand functional immunogenicity assessment capabilities for multivalent vaccine programs.

Primary Responsibilities

• Perform laboratory experiments supporting development of a multiplex ADCP assay.
• Prepare and characterize antigen‑coated fluorescent bead reagents.
• Conduct cell‑based functional assays using THP‑1 cells and vaccine study samples.
• Support flow cytometry sample acquisition and data analysis.
• Evaluate assay performance, reproducibility, and multiplex feasibility.
• Analyze experimental data using Excel and other analytical software tools.
• Collaborate with scientists to troubleshoot and optimize assay conditions.
• Maintain accurate laboratory documentation and experimental records.
• Prepare technical summaries and presentations of project findings.
• Present project outcomes at the end‑of‑summer intern symposium

Required Skills

• Basic laboratory experience in immunology, molecular biology, cell biology, or related disciplines.
• Familiarity with aseptic laboratory practices.
• Strong analytical and problem‑solving skills.
• Ability to analyze data using Microsoft Excel or equivalent software.
• Excellent organizational and documentation skills.
• Effective verbal and written communication skills.
• Ability to work independently and collaboratively in a research environment.
• Strong attention to detail and commitment to scientific rigor.

Preferred Skills

• Experience with flow cytometry, including sample preparation and data analysis.
• Familiarity with cell culture techniques and/or THP‑1 cell handling.
• Experience with immunogenicity, vaccine, or antibody‑based assays.
• Familiarity with FlowJo or similar flow cytometry analysis software.
• Knowledge of antibody effector functions, Fc‑mediated immunity, or phagocytosis assays.
• Experience with multiplex assay platforms or bead‑based technologies.
• Exposure to data visualization or statistical software such as GraphPad Prism, R, Python, or JMP.
• Prior research experience through coursework, internships, co‑ops, or academic laboratory projects.

Learning Opportunities

• Functional immunology assay development and optimization.
• Multiplex assay technologies and vaccine bioanalytics.
• Flow cytometry and cell‑based assay platforms.
• Experimental design, troubleshooting, and data interpretation.
• Bioanalytical support for vaccine development programs.
• Scientific communication through technical reporting and presentations.
• Cross‑functional collaboration within a pharmaceutical research organization.

Expected Deliverables

• Proof‑of‑concept evaluation of multiplex ADCP assay feasibility.
• Experimental data package comparing multiplex and singleplex assay performance.
• Recommendations for future assay optimization and implementation.
• Final scientific presentation summarizing project objectives, methods, results, and impact.
