While Covid-19 vaccines for infants under five have yet to be approved by the Centers for Disease Control and Prevention (CDCP), the agency is working on distributing the shots. It has told local and state health officials that the first Covid-19 shipments could arrive as early as February 21st.

The CDC will begin distributing 10 million doses within three phases when the Food and Drug Administration allows the low-dose 3-microgram dosage. PfizerAnd BioNTechAccording to Sunday’s quietly released planning document, the vaccine is recommended for children aged 6 to 4 years old. According to the CDC, state and local officials may begin preordering vaccines Monday. They will receive their first vaccine shipments starting on Presidents Day.

It is up to local officials to determine the distribution routes and locations of vaccines. Administration cannot start until the CDC gives its approval. It will probably do this quickly once the Food and Drug Administration approves it.

On Tuesday, the FDA will host a meeting of its panel of experts outside vaccination.

The CDC stated in the planning document that enough vaccines have been purchased by the federal government to vaccinate 18 million U.S. children aged 6 months to four years.

The FDA moved quickly to get shots approved on an urgent basis, amid increasing pressure from doctors and parents.

Pfizer, BioNTech and the FDA requested that they authorize two doses of the vaccine. The final three-dose vaccine will be available for children aged 5 to 5.

Pfizer changed its clinical trial protocol in December in order to assess a third dose. The first two shots failed to produce an adequate immune reaction in children 2-4 years old. Pfizer, BioNTech and others said that they would submit data to FDA on the third dose in the next few months.

Parents will have the ability to get their first two doses of Pfizer for their children by expediting the authorization process. This allows them to prepare for the third and final dose. Pfizer claimed in December there had been no safety concern with the three microgram dose. It is smaller than the adult 30 microgram shot.

CNBC’s Albert Bourla, CEO of Pfizer, stated Tuesday that data was good and that he thinks the FDA will approve two doses. When the briefing materials for the FDA’s vaccination advisory committee are released, data on the vaccine will be available Friday. To discuss shots for infants and toddlers, the FDA’s vaccine advisory committee will meet February 15, 2015.
