Rates of severe disease and hospitalizations for COVID-19 vary greatly by age for children, with children under 5 years having the greatest risk of being hospitalized.1 Race and ethnicity, family income levels, and where they live can also increase a child’s risk for severe illness.2, 3 That is why it is important that children of all backgrounds participate in this study – to reflect the diversity of families around the world looking for better protection against COVID-19.
Though most children aren’t seriously harmed by COVID-19, some do become very sick. With new COVID-19 variants continuing to emerge, getting vaccinated can help protect your child from serious illness. If you are thinking about vaccinating your child against COVID-19 for the first time, consider joining our ongoing vaccine clinical trial.
This study will help us learn how well our updated COVID-19 vaccine works in children who have not been previously vaccinated and see if the number of recommended doses can potentially be reduced for children under the age of 5. The study vaccine has been authorized by the United States Food and Drug Administration for children at least 6 months of age. It is designed to protect against the newer COVID-19 variant called XBB.1.5.
Your child’s participation in this study could reduce their risk of getting COVID-19. It will also help to improve the vaccine options available to protect children around the world against the newest COVID-19 variants.

Get started — See if you may be eligible
Answer a 2-minute questionnaire.
A first step as you consider this study is to answer a 2-minute online questionnaire about your child’s health and medical history. If your answers show the study might be a good fit for your child, you may choose to have your contact information shared with a Pfizer Clinical Trial Contact Center Navigator.
Speak with a study representative.
If you’re interested, a Pfizer Clinical Trial Contact Center Navigator will call you and do a more detailed review of the study and your child’s medical history to see if they may be able to participate and be referred to a study clinic that you select.
Confirm your child’s eligibility.
Your answers to these questions will only be linked to you if your responses indicate that your child 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 or your child. Only the study staff can determine if your child meets the study’s eligibility criteria and is able to enroll in the study.
