The Centers for Disease Control and Prevention hasn’t yet approved Covid-19 vaccines for kids under 5, but it’s laying the groundwork to distribute the shots, telling state and local health officials they could receive their first shipments by Feb. 21. The CDC plans to roll out 10 million doses in three phases as soon as the Food and Drug Administration authorizes the lower-dose, 3-microgram Pfizer and BioNTech shot for children 6 months to 4 years old, according to a new planning document quietly issued Sunday. State and local health officials could start preordering the first doses Monday and will start receiving vaccine shipments on Presidents Day, according to the CDC. (Kimball, 2/9)

The Centers for Disease Control and Prevention has told coronavirus vaccine providers to be ready to receive shots for children younger than 5 by Feb. 21 — just a week after the Food and Drug Administration is expected to make its recommendation on emergency-use authorization. If the vaccine receives the green light, an initial 10 million doses are expected to be ready for shipment, with the first half of the batch available on Feb. 21 and the second on Feb. 25, according to an updated pediatric vaccination planning guide released this week.

Scientific advisers to the Food and Drug Administration will decide next week whether to endorse giving two doses of the Pfizer-BioNTech coronavirus vaccine to children 6 months to 4 years of age, before clinical trials have shown whether a full course of three doses is effective. Such an authorization would be a first for the agency, many experts say. Interim results suggested that two doses of the vaccine did not produce a strong immune response in children aged 2 through 4. Results from trials of the third dose are expected in a few weeks. (Mandavilli, 2/10)

Elana Banin is counting down the seconds until she can get her baby and toddler vaccinated — a moment she is hoping will finally lift a weight that has continued to bear down on her and similar parents nearly two years into the pandemic. “There isn’t a day or a minute that goes by that we aren’t acutely aware that our kids are at risk and all of our decisions are calculated accordingly,” Banin, who lives in New York City, said. “Our lives revolve around the fact that they aren’t vaccinated, which in a way I hope desperately will change the second the vaccine is available for their age group. We will be first in line.” (Pettypiece and Seitz-Wald, 2/10)

Even if vaccination of young children begins in April, it will be summer before they have had three doses, noted Dr. Diego Hijano, a pediatric infectious disease specialist at St. Jude Children’s Research Hospital, and an investigator for the Pfizer-BioNTech trial. “For sure, by summer we may have a variant of concern that’s spreading around.” (Mandavilli, 2/9)

A prospective cohort study of US children diagnosed as having COVID-19 reveals that certain demographic characteristics, preexisting chronic diseases, and initial vital sign and lab values may portend disease severity, a finding that the researchers said could help improve outcomes. The University of Colorado-led study involved 167,262 COVID-19 patients 18 years and younger tested for COVID-19 at 56 US National COVID Cohort Collaborative facilities up to Sep 24, 2021, before the emergence of the highly transmissible Omicron SARS-CoV-2 variant.
