Moderna Seeks FDA Approval for COVID-19 Vaccine for Children Under 6

In a positive development for parents of young children, Moderna has requested the FDA’s approval for its COVID-19 vaccine for kids aged 6 months to 6 years. This move brings hope to the 18 million youngest Americans who are yet to be vaccinated, although the timeline for availability remains uncertain. A Moderna representative indicated that the necessary documentation will be submitted to the FDA by May 9, after which the agency will deliberate on the request. Stéphane Bancel, Moderna’s CEO, expressed confidence in the vaccine’s safety and efficacy, stating, “We believe mRNA-1273 will provide a safe defense for these children against SARS-CoV-2, which is crucial in our ongoing battle against COVID-19 and will be particularly welcomed by parents and caregivers.“

Clinical Trial Results

Clinical trial results revealed that the vaccine generates an antibody response in children that is comparable to the response seen in adults aged 18 to 25. While the trial was not large enough to definitively measure overall effectiveness, preliminary data indicate that it is 51% effective against symptomatic cases in children under 2 years and 37% effective for those aged 2 to 5. Although this effectiveness is lower than what was observed for adults last year, it still offers significant protection. Moderna noted that the reduced effectiveness was largely due to the predominance of the Omicron variant in the infections recorded during the trial. Importantly, no instances of heart inflammation—an issue of concern with both COVID-19 and its vaccines—were reported, nor were there indications of higher fever rates compared to routine vaccinations.

Timeline for Vaccine Availability

As for when toddlers and infants might be able to receive the vaccine, this hinges on numerous factors. Moderna is also seeking approval for vaccines for children aged 5-11 and adolescents aged 12-17. It remains unclear whether the FDA will evaluate all three requests simultaneously or prioritize the vaccine for younger children, who have been unprotected throughout the pandemic. Additionally, Dr. Leon Tran, a leading medical advisor, suggested that the FDA may wait for Pfizer’s clinical trial results to conduct a comparative review before issuing approvals, similar to the process for adult vaccines. Pfizer is developing a three-dose vaccine at one-tenth the adult dosage, while Moderna’s vaccine consists of two doses at one-fourth the adult strength. The FDA has indicated that it may not review the data until June, as it consults an external panel of experts for a thorough assessment before granting approval for the youngest demographic. Consequently, parents may need to exercise patience as this process unfolds. Moderna has also indicated that it is pursuing similar approvals in other countries.
