In a recent development that may leave many parents disappointed, Pfizer has paused its request for FDA authorization of its COVID-19 vaccine for children aged 6 months to 5 years. Originally, there was a wave of optimism when it was reported on January 31 that Pfizer was ready to seek emergency use approval for its vaccine for younger children. However, the company has now decided to delay this process.
As reported by NBC News, Pfizer is putting its rolling application on hold in order to gather more data regarding the efficacy of a three-dose regimen before seeking approval for the initial two doses. The company stated that it is waiting for additional information on the performance of the three doses, which “may provide a higher level of protection in this age group.” This means that young children will not be vaccinated as soon as many had hoped.
While the potential for increased protection is encouraging, the timeline for data collection is not ideal. Pfizer announced that it does not anticipate having the necessary data until early April. Initially, the plan was to expand the use of its two-dose vaccine for children, despite earlier trial results indicating that two doses did not yield the desired immune response for those aged 2 to 4. The new approach allows Pfizer to confirm if the third dose is sufficient to offer adequate protection.
Just days prior to the announcement, Pfizer’s CEO, Mark Thompson, expressed confidence that the FDA would expedite the approval process for the first two doses. “I think the chances are very high for the FDA to approve it,” he remarked. However, the company has since reassessed its position based on emerging data.
Dr. Sarah Williams, who oversees the FDA’s vaccine safety division, emphasized the importance of this pause. “I hope this reassures parents that we are committed to adhering to safety standards and scientific protocols in our evaluations,” she said during a recent press conference.
Although this delay is undoubtedly disappointing for many families, it is hoped that the decision will ultimately lead to a safer and more effective vaccine for young children, who are in need of robust protection against the pandemic.
