Before You Continue...

A first step as you consider participation in a research study is to answer a 5-minute online questionnaire about your health and medical history to see if any of our studies are a good fit for you. We will also collect your name, phone number, physical address, and email address so that a study representative may contact you about research studies enrolling in your area. Your contact information will not be used for any other purposes and all information is stored on servers in the United States.

If you are a potential candidate for one of our research studies, you may choose to be referred to a study clinic that you select. We will share your name, phone number, physical address, and email address, as well as your responses to the pre-screening questions, with the study clinic and those working on their behalf. A study representative will then contact you to discuss next steps regarding the study. If you're interested in the study, they will do a more detailed review of your medical history to see if you are able to participate. Only the study staff can determine if you meet the eligibility criteria to enroll in the study.

The individual responses you provide will also be used by Pfizer, or our partners supporting our research studies, to look for areas of improvement such as revising the criteria for participation. Pfizer study team members and our partners will have access to reports containing aggregated data that will not be directly linked back to you.

Sorry, you are not eligible at this time or enrollment for your age group is currently closed.

Please enter your information below if you would like to be contacted about future clinical research opportunities. By submitting this form, you confirm that you are at least 18 years of age (or the legal age of consent in your state if it is over 18) and that Pfizer or our partners may contact you about information related to research studies enrolling in your area.

SARS-CoV-2 (the virus that causes COVID-19) and respiratory syncytial virus (RSV) are common respiratory viruses. These viruses often spread at the same time as the flu virus. They cause similar symptoms like cough, fever, and sore throat. Millions of people get sick from these viruses each year, and they can be life-threatening for many people.

  • Age, chronic health conditions, disabilities, lifestyle, race, and ethnicity can all impact someone's risk for severe COVID-19 infection.
  • Adults over 50 are at increased risk of hospitalization and death from COVID-19. 1
  • More than 81% of COVID-19 deaths occur in people over 65. 2
  • Infants, children, and adults over 65 or those with chronic medical conditions are at increased risk for severe RSV infection.
  • Each year in the U.S., an estimated 60,000 to 160,000 adults over 65 are hospitalized for RSV. 3
  • 6,000 to 10,000 people die every year due to RSV infection. 3

Pfizer's commitment to developing vaccines for respiratory infections

Pfizer is committed to developing vaccines that provide protection against serious respiratory infections. In addition to the COVID-19 vaccines we developed in partnership with BioNTech, we have been researching a vaccine for RSV.

We are now developing a combination vaccine for COVID-19 and RSV. A single vaccine has the potential to protect more people against infection from both viruses with one convenient injection.

Participation matters

Factors such as genetics, race, ethnicity, gender, and age, can affect a person's risk factors for severe infectious diseases and how they respond to a vaccine. In the U.S., African Americans, Alaskan Natives, American Indians, Latino people, and adults over the age of 65 are more significantly impacted by severe illness and hospitalizations from COVID-19 and RSV than other groups. 3,4,5

That is why it is so important that clinical trials include people of all backgrounds. Everyone needs to be represented. With your help, we can advance research that may improve protection against COVID-19 and RSV for everyone.

About this study

The vaccine being studied is a combination of Pfizer and BioNTech's bivalent COVID-19 vaccine and Pfizer's investigational RSV vaccine. Together, the combination study vaccine could provide protection against multiple types of COVID-19 and RSV.

This study is evaluating the response to the combination study vaccine compared to receiving a bivalent COVID-19 vaccine and the investigational RSV vaccine as separate vaccinations. Since COVID-19 and RSV typically spread at the same time as flu, the study will also evaluate the effects of receiving the combination study vaccine together with a flu vaccine.

Your participation in this research study will help us understand if combination vaccines can protect against multiple serious respiratory infections. Thank you for taking the time to learn more.

Who can participate?

This study is enrolling adults who:

Are at least 65 years of age
Are generally healthy or have stable chronic conditions
Have not been diagnosed with COVID-19, RSV, or flu within the last four months
Have not received a flu vaccine within the last four months
Have received at least three prior doses of an mRNA COVID-19 vaccine (Pfizer-BioNTech or Moderna), and the last dose was a bivalent vaccine* given at least five months ago
*In the U.S., all COVID-19 vaccine doses administered after September 1, 2022 were bivalent.
There will be other study requirements that the study team will discuss with you.

What to expect

This research study will last about six months. Participants will be asked to attend at least three study visits, including one follow-up phone call.
Some people will get the combination study vaccine while others will receive separate vaccinations for COVID-19, RSV, and/or flu. The study team will explain more about which vaccination(s) you may be assigned to receive.
Participants will need to track any changes in their health for seven days after their vaccination visit. To make this easier, they will be given an electronic diary (eDiary) to use, or they can download the secure eDiary app to their smartphone.
The study vaccine(s) and study-related procedures will be provided at no cost. Participants do not need health insurance to take part. Participants will also be reimbursed for any study-related expenses.

Your safety is the top priority

Safety is always the top priority of any research study. Before you join the study, you will be given all of the details about participation, including potential benefits and risks. Your health will be carefully monitored throughout the study by the study team.

Volunteering is your choice

Choosing to volunteer for a clinical trial is very personal and many factors may weigh in your decision-making. To decide if this research study is a good fit, it's important to understand the process and what is required. If you would like to participate, you will provide your consent (permission) before joining the study. You are also free to stop being in the study at any time, for any reason.
