Answer a 5-minute questionnaire.

A first step as you consider this study is to answer a 5-minute online questionnaire about your health and medical history. If your answers show the study might be a good fit for you, you may choose to be referred to a study clinic that you select.

Speak with a study representative.

If you’re interested, you will then be asked to provide your contact information for a study representative to contact you and discuss the next steps.

Confirm your eligibility.

Your answers to these questions will only be linked to you if your responses indicate that you may be eligible to participate in this study and you choose to share your contact information with the study team. Pfizer study team members and our partners will have access to reports containing aggregated data that will not be directly linked back to you. Only the study staff can determine if you meet the study’s eligibility criteria and are able to enroll in the study.
