Pneumococcal disease can be serious for children . Fortunately, there are vaccines available that have been proven safe and effective, dramatically reducing rates of pneumococcal disease in children.

The CDC recommends that all children get vaccinated for pneumococcal disease. Today’s vaccines defend against many strains of pneumococcal bacteria, but they don’t protect against all. That’s why we’re working to develop a vaccine that aims to expand protection against more bacterial strains than our current pneumococcal vaccines.

Participating in these studies

Joining a clinical trial is an important and personal decision. Taking part could potentially help improve vaccine protection not only for your child, but also other children in the future. We thank you for considering participation as an option that may be right for your family. 

These studies are enrolling children of different age groups. The age and vaccination history requirements vary between studies. Click ‘Learn more’ to see if any of these studies may be a good fit for your child.

Condition

Pneumococcal disease

Age

6 weeks to 15 months old

Vaccination status

Both vaccinated and unvaccinated children (depending on their age)

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 below. Only the research study staff can determine if your child qualifies to enroll in the study.

The PG4 Pneumococcal Vaccine Studies for Children

Recruiting
Pneumococcal vaccine clinical trial for babies 6 to 14 weeks old

This study is researching how well the study vaccine (called PG4) works in babies who have not started their routine pneumococcal vaccine series. All children will receive either 4 doses of PG4 or 4 doses of Prevnar 20® (Pfizer’s current approved and licensed pneumococcal vaccine).

Recruiting
Pneumococcal vaccine clinical trial for toddlers 12 to 15 months old

This study is researching how well the study vaccine (called PG4) works in children who have already received 3 doses of Prevnar 20®. All children will receive either 1 or 2 doses of PG4 or 1 dose of Prevnar 20®.

Your family could potentially make a difference

Participation by children of all backgrounds is critical to developing vaccines that protect against infectious diseases. 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.

Vaccine clinical trials & your child

Vaccines are considered one of the greatest public health advances of all time. In the last 50 years, the World Health Organization estimates over 100 million children’s lives worldwide have been saved by vaccines. 

But there is more work to be done. Infectious diseases still threaten the health of children worldwide. 

Children’s bodies are still developing, and the vaccines used in adults may affect them differently. That’s why potential new vaccines have to be studied in both adults and children. Clinical trials provide valuable information about how well vaccines work and whether they are safe for children of all ages. 

As you consider clinical trial opportunities for your child, remember that you’re not only helping your child, but contributing to a healthier future for children around the world!
