The Pfizer Clinical Research Unit (PCRU) in New Haven invites both new and seasoned volunteers to visit us for a generic screening.

The purpose of this screening is to identify potential candidates for current and upcoming studies at the PCRU, specifically those who would be interested in vaccine clinical trials. Your results will be used to create a snapshot of your current health that can be used to pre-assess your eligibility for studies and update your records, which may help us offer you more appropriate trials in the future.

Completing this screening is not a commitment to participate in a study and you may still need to complete a study-specific screening to participate in future trials.

Who may participate

Clinical trial participants are an essential part of medical research. While participating in this generic screening does not include taking a study drug, it can help us understand which studies might be a good fit for you and can also give you first-hand experience of our site and how clinical trials work if you are new to research.

This screening is seeking adults over 65 who are in overall good or stable health, meaning that the participants are generally healthy and have not had major changes to their health status over the last several months (no new prescriptions or diagnoses, no hospital stays). If you’re unsure about what would be considered “healthy” you can give us a call and will assess this with you over the phone.

In addition to the criteria listed, participants must be:  

  • Willing to travel to our facility in New Haven, CT
  • Comfortable with medical procedures like blood draws
  • Interested in future clinical trial participation

*participants may be eligible to receive a bonus for travel, ask our staff for details

There are other requirements for participation in this study. The study staff will explain these to you during the screening process.

Do you know someone who may meet these requirements? Refer a friend and you may be eligible to receive a bonus.

Each clinical study has its own guidelines for who can participate, called eligibility criteria. However, only the research study staff can determine if you qualify to enroll in the study.

What to Expect

If you would like to take part in this screening, you can click “Get started” and contact us by phone or by completing and submitting the form at the bottom of this page. You will then be asked to complete a pre-screening over the phone which involves answering some questions about your medical history and other details to see if you would be eligible for this screening, and then we’ll make an appointment for you to come in for the in-person appointment.

The in-person screening may take 2-4 hours and involves a more thorough review of your health history with our clinical staff and other health tests such as a blood draw, blood pressure checks, and ECG. All of the procedures will be discussed with you prior to any data collection and your participation is always voluntary.

After completing the screening, you will receive compensation up to $175 on a pre-paid debit card within 2 weeks of the visit date and a staff member will follow up with you to share your results and let you know about upcoming trials that may be of interest. Completing this screening is not a commitment to participate in future studies and you may still need to complete a study-specific screening.

All of the study procedures will be clearly explained to you prior to conducting the screening.
