Share some basic health info, and we'll take it from there

We’re aiming to enroll about 1 million people who represent the diversity of the United States. This includes people with and without medical conditions.

To join PfizerLink, you must be a resident of one of the 50 states of the United States or the District of Columbia. You must also be at least 18 years old in most states (at least 19 in Nebraska or Alabama and at least 21 in Mississippi).

Pfizer is committed to maintaining the privacy and confidentiality of every participant in PfizerLink. More details about PfizerLink’s privacy practices can be found in the informed consent document that you will review and sign if you decide to join PfizerLink. We will regularly review and improve our privacy and security practices to protect your information. 
 
When we publish or share any PfizerLink research results, only summary information will be provided. We will not publish or share results that identify any specific individuals.

Anybody can consider participating in clinical research.

When you join a clinical trial that’s studying a condition you have, you may help us evaluate a potential treatment for that condition.

There are also clinical trials that need volunteers without a specific disease or condition. As a participant, you might contribute to learnings about a potential vaccine, or about a study medicine before it’s given to people with a condition.

Each clinical trial has its own criteria for who may participate. These are called eligibility criteria.

Examples of eligibility criteria include a person’s:

• Age and sex
• Type and/or stage of disease
• Overall health
• Personal treatment history

Informed consent is one of the most important tools to help you understand how your rights, safety, and well-being will be addressed during a study. At your appointment, the study team will review the details of the study with you, including possible risks and benefits, so you will know what to expect.

If you decide to participate, you will be asked to sign an informed consent document that is specific to the study. That will confirm you understand the study and are willing to continue with screening and to take part in the study, if you are eligible.

You’ll meet with the study doctor and their staff to confirm whether you fit the eligibility criteria and are able to participate. This may include a more detailed review of your medical history and a physical exam. It may also include blood work and additional tests related to your condition.

Participating in the study is always voluntary. The decision to join is personal, and it is yours. You can still take part in PfizerLink even if you choose not to participate in a Pfizer clinical trial.
