Pfizer-BioNTech reported on Friday that the low-dose COVID-19 vaccine trial for children under 5 fell short, as it did not elicit a strong immune response in children aged 2 to 5. This outcome is disappointing for parents eagerly awaiting a vaccine for their little ones.
In the ongoing clinical study, kids aged 6 months to 5 years received a dose that is one-tenth of what adults receive. While the vaccine prompted a satisfactory immune response in children under 2, the older group did not respond adequately. Rather than increasing the dose for this age bracket, researchers will now administer a three-dose series instead of the initial two doses, a modification that has received approval from the Food and Drug Administration (FDA). Pfizer plans to seek FDA clearance for this three-dose regimen in early 2022, similar to the two shots plus a booster approach for adults.
According to a Pfizer spokesperson, the aim is to evaluate the potential protective effects of the third dose. “We are studying 3 micrograms at this time,” she stated. Although the two-dose schedule did not yield the desired immune response for the older participants, it doesn’t mean all progress is lost. The trial will continue for an additional two months to allow for the extra shot. If the response remains inadequate, a new trial may be necessary to adjust the dosage or the vaccination schedule for this age group.
Dr. Michael Turner, a vaccine specialist at Children’s Hospital of New Jersey, emphasized that even if the two-shot regimen fails to prevent COVID-19, it could still reduce the severity of the disease. He remarked, “The primary aim of this vaccine is to avert serious illness.”
In a future study, Pfizer will also examine a three-dose series for children aged 5-12, with the dosage remaining at 10 micrograms, or one-third of the adult dose. For individuals over 12, the standard adult dose is 30 micrograms.
On a positive note, Pfizer confirmed that “no safety concerns were identified” throughout the trial, which is still ongoing. For more in-depth information about pregnancy and home insemination, visit the CDC, an excellent resource on the subject.

Summary
Pfizer’s COVID-19 vaccine trial for children aged 2 to 5 has produced disappointing results, prompting a switch to a three-dose regimen to improve immune responses. While the vaccine generated a sufficient immune response in younger children, older participants did not show the expected results. The trial will be extended to assess the third dose’s efficacy, with no safety concerns reported thus far.
