How it Works

Health Answers by Pfizer is a free health app powered by generative AI that goes beyond simple Q&A. It delivers personalized insights to help you take charge of your health & wellness—all in one place. Learn about symptoms and what they might mean, understand a recent diagnosis, or explore ways to live a healthier lifestyle. Designed to be personal and easy to use so you can focus on what matters most: your health.

Trusted and independent sources

We start by sourcing content from well recognized organizations that have long-standing reputations for unbiased information, such as Harvard Health Publishing, Healthline, First Databank, and others. These sources have been selected based on their science-based approach and editorial independence from commercial influence or interest. We supplement this with millions of medical journal abstracts and articles from the National Library of Medicine and other public-domain content, such as the CDC, FDA and National Institutes of Health. Health Answers by Pfizer curates information from these independent sources, which each have their own processes and standards for validating and publishing content.

Unbiased answers and articles

Health Answers by Pfizer harnesses the power of Generative AI to provide a conversational experience, allowing you to ask questions and immediately delivering you AI-created summaries of the most useful information available across our vast library of sources. Leveraging multiple sources is intended to help ensure that our answers and articles are complete and not biased towards our company or affiliates. Health Answers by Pfizer responses are not the opinions of Pfizer or its employees.

Commitment to transparency

We will provide the verified sources from which your answer is generated. If the answer to your question does not rely on any of our independent sources, it will be clearly labelled as “unverified”.

An answer is considered "unverified" when it was not created using Health Answers by Pfizer's verified and trusted health and wellness sources. This happens when we don't have enough source content to generate a verified answer using Health Answers by Pfizer’s standards. For your convenience, we generate an unverified answer using content from the open internet. Because information from the open internet may be out-of-date, inaccurate, or potentially harmful, Health Answers by Pfizer does not endorse or stand behind this information and it should be consumed at your own risk with this understanding.

Ensuring readability

Sometimes health and wellness information is difficult to understand, so we strive to make Health Answers by Pfizer’s responses clear, jargon free, and easily understood. Gen AI can make mistakes, so it is always important to check your answers with the original sources and qualified health professionals.

Personalized answers based on your health profile

Sometimes the answers to health questions can change based on your health profile. Begin by answering some simple questions in your Health Profile -- such as age, sex assigned at birth, height, weight, smoking history and health conditions. Then enable personalization and ask any health question.

This feature will personalize answers to your health questions based on the information you choose to add to your Health Profile. Answers are only for informational purposes, and you should always consult a health care professional for any personalized advice.

Experimental

Personalization uses experimental AI to determine which parts of your Health Profile are relevant to the question you are asking. Please note that personalization is limited to the information available in your Health Profile, which may not give a complete picture of your health. Some questions may not get a personalized answer; for example, we do not personalize questions about medications at this time.

Controllable

You control when this feature is enabled, simply by toggling it on and off. This way, you can keep personalization on when asking for yourself or turn it off when you have a question about your family and friends. Personalized answers may take longer to answer than non-personalized answers.

Feedback Encouraged

We welcome your feedback on this feature. You can provide it directly from within the product, using our “Share feedback” link.

Dynamically generated insights, tailored for you

The For You feed

We know your health evolves over time, and it often involves learning about something new. With the For You feed, you select Topics, or create your own, and Health Answers by Pfizer proactively generates relevant questions and answers so you can discover and learn over time. It’s designed to be useful and simple, when you may not know exactly what to ask.

Quality control and oversight

To make sure you are always getting the best possible information, we have the following procedures in place to help ensure our quality and continuously improve:

AI is not human and is still experimental, and that’s why we pass our answers through a filter that helps ensure faithfulness to the original source material.
As described in detail above, in the cases that we do not have the content from our trusted sources to generate a verified answer we will provide an ‘unverified’ answer for your convenience.
We have independent clinicians across specialties routinely audit the pre-generated articles and randomly sample our AI-generated answers to help ensure they are consistent with current clinical practice guidelines or standards of care and that our safeguards are appropriate.
The independent clinicians also review articles and answers to help ensure relevance and clarity; however, as with all Gen AI, hallucinations and inaccurate or incomplete responses may still occur. Results from the independent clinician audits are reviewed with the engineering team to identify opportunities for improvement as part of continuous quality enhancement.
We have an independent scientific and technology advisory board that reviews and advises us on our Gen AI policies and procedures.
You will find “Share Feedback” links on every Health Answers by Pfizer answer and article — so you can let us know quickly and easily if something doesn’t look right. By clicking this link, we can check the question and answer specifically.
