As new variants continue to emerge, getting vaccinated is one of the best ways to protect your child from serious illness. If you are thinking about vaccinating your child against COVID-19 for the first time, consider joining one of our ongoing vaccine clinical trials.

These studies will help us learn how well our updated COVID-19 vaccine works in children who have not been previously vaccinated.

The study vaccine has been authorized by the United States Food and Drug Administration for children at least 6 months of age and offers more comprehensive protection against newer variants.

There is no cost to participate, and you will be compensated for completing study-related activities.

COVID-19 Vaccine Clinical Trials for Children

Participating in these studies

Joining a clinical trial is an important and personal decision. We thank you for considering participation as an option that may be right for your family.

These studies are enrolling children from different age groups who have not been vaccinated for COVID-19. To see if your child may qualify to participate, click ‘Learn more’ to get started.

If the study appears to be a good fit for your child and you would like to be referred to a study clinic, a study representative will call you to talk about next steps.

No prior vaccines for COVID-19

This information is a summary of the eligibility criteria across the studies in this program. Each study will have its own unique requirements for who may participate (eligibility criteria). To learn more about the requirements for a study that is actively recruiting, visit the study’s webpage above. Only the research study staff can determine if your child qualifies to enroll in the study.

Why Vaccination is Important

Though the risk of severe COVID-19 in children in much less than that seen in adults, it is not zero. Since the start of the pandemic, children from all age groups have experienced severe COVID-19, hospitalizations, and long-term complications. Even with mild or no symptoms, children may be at risk of developing MIS-C, a rare but life-threatening inflammatory condition related to COVID-19.

The CDC and American Academy for Pediatrics recommend getting your child vaccinated to help prevent symptomatic infection, severe illness, and long-term complications of COVID-19.

Help Make a Difference

Participation by children of all backgrounds is critical to developing vaccines that protect against infectious diseases like COVID-19. The greater the diversity among families involved in clinical research, the more we can learn about potential vaccines and how they work in children, including those most at-risk because of their age, race, ethnicity, or where they live. Each new vaccine breakthrough helps us reach more families and communities to prevent and reduce the spread of disease.
