There’s promising news for parents of children under 12. While adolescents aged 12 and older can receive the COVID vaccine, younger kids are still awaiting their turn. As vaccination rates rise, leading to a decline in COVID infections, parents are eager to safeguard their little ones. Recently, Pfizer announced updates on their COVID-19 vaccine trials for younger children, having completed Phase I and now moving into Phase II and III trials for those aged 6 months to 11 years.
What Does the Next Phase Entail?
Given that children are considerably less likely to experience severe outcomes from COVID-19 compared to adults, pharmaceutical companies are carefully balancing the vaccine’s effectiveness against potential side effects. Consequently, Pfizer and BioNTech are conducting trials using lower doses for elementary school-aged children, with even smaller doses for infants. This approach, known as “age de-escalation,” is standard in pediatric drug testing. Vaccines are first tested in healthy adults, and once deemed safe, the trials progress to younger age groups to ensure safety and efficacy in generating antibody responses.
With COVID-19 posing risks to children, particularly those with underlying health issues, ensuring the safety of our children is vital as the U.S. continues to ease restrictions this summer.
What Is Being Evaluated?
Pfizer-BioNTech has previously gained authorization to vaccinate adolescents in the U.S., having tested the vaccine on over 2,000 participants aged 12 to 15. Their findings revealed that the vaccine effectively prompted an immune response without severe side effects. Furthermore, a small Phase I study involving around 100 children assessed the optimal dosage that would balance immune response with manageable side effects. Results are expected by September or October, when Pfizer plans to seek Emergency Use Authorization from the FDA.
The pediatric trials categorize participants into three age groups: 5 to 11 years, 2 to 5 years, and 6 months to 2 years. The doses being tested are lower than those for older children and adults, as different dosages are explored to determine the most effective for each age bracket.
Pfizer-BioNTech is currently enrolling about 4,500 children aged 5 to 11 for the next phases of the study, with trial locations in the U.S., Finland, Poland, and Spain. Trials for younger children aged 6 months to 4 years are anticipated to begin shortly. Interested parents can find more information about volunteering their children for these trials here. Other companies, including Moderna and Johnson & Johnson, are also conducting similar trials.
When Could a Vaccine Be Available for Younger Kids?
Pfizer-BioNTech intends to submit their Phase II and III results to the FDA by September or October. This will provide insights into the safety and effectiveness of the vaccine for children aged 6 months to 11 years. While it’s unlikely that the vaccine will be ready before the start of the 2021-2022 school year, it may become available by the end of 2021.
Once Pfizer requests Emergency Use Authorization, the FDA will hold an emergency meeting with independent experts to evaluate the trial data. Initially, the focus will likely be on the 5 to 11 age group, followed by younger children. If the FDA concludes that the vaccine’s benefits outweigh any risks, the Centers for Disease Control and Prevention (CDC) will review the data as well. If approved, individual state panels will then decide on eligibility criteria.
The authorization process for COVID vaccines across different age groups will be staggered, prioritizing older children first. This entire process is expected to take several weeks, so patience is essential.
In the interim, keep younger children protected from COVID by ensuring they are current on all vaccinations. Adhere to CDC guidelines by having them wear masks, avoiding crowded places, opting for well-ventilated areas—especially outdoors—and practicing regular hand hygiene.

As information about COVID-19 is continuously evolving, stay informed by consulting local public health departments and the CDC.
Summary:
As trials for the COVID vaccine for children under 12 progress, Pfizer-BioNTech is currently in the Phase II and III stages, aiming for potential availability by late 2021. With rigorous testing protocols in place, parents are encouraged to keep abreast of updates and maintain preventive measures for their children.
