CDC recommends updated bivalent COVID-19 vaccine for children 6 months of age and older

On Friday Dec. 9, the Centers for Disease Control and Prevention (CDC) recommended the use of the updated (bivalent) Moderna and Pfizer-BioNTech COVID-19 vaccines to include use in children 6 months of age and older.

Pfizer COVID-19 bivalent vaccine

  • Children 6 months through 4 years of age who have received two doses of the original (monovalent) three-dose primary series of the Pfizer-BioNTech COVID-19 vaccine and have not yet received the third dose of their primary series will now receive the updated (bivalent) Pfizer-BioNTech COVID-19 vaccine as the third dose in their primary series.
  • Children 6 months through 4 years of age who have already completed their three-dose primary series with the original (monovalent) Pfizer-BioNTech COVID-19 vaccine will not be eligible for a booster dose of an updated bivalent vaccine at this time.
  • With this authorization, the monovalent Pfizer-BioNTech COVID-19 vaccine is no longer authorized for use as the third dose of the three-dose primary series in children 6 months through 4 years of age.

Moderna COVID-19 bivalent vaccine

  • Children age 6 months through 5 years are now eligible to receive a single booster of the updated (bivalent) Moderna COVID-19 vaccine at least two months after completing a primary series with the original (monovalent) Moderna COVID-19 vaccine.

Currently there are no recommendations for “mixing” vaccine products in younger children. Refer to the CDC: Clinical Guidance for COVID-19 Vaccination for more detailed information, especially about children who change age groups during their primary series.

For details on CDC’s recommendations and FDA’s authorization, refer to the following media statements: CDC Expands Updated COVID-19 Vaccines to Include Children Ages 6 Months through 5 Years and Coronavirus Update: FDA Authorizes Updated (Bivalent) COVID-19 Vaccines for Children Down to 6 Months of Age.

The FDA EUA fact sheets for health care providers and recipients and caregivers have been updated and can be found at Comirnaty and Pfizer-BioNTech COVID-19 Vaccine and Moderna COVID-19 Vaccines. CDC has also updated the Interim Clinical Considerations for Use of COVID-19 Vaccines. MDH is currently updating resources to reflect this change and can be found at COVID-19 Vaccine Providers

Tips for submitting nonviable forms in MIIC

Avoid submitting more than one nonviable form in the same day. Minimize the number of entries to make it easier for you to submit and for us to process.

  • We advise submitting weekly totals when possible. You can add up totals for each lot over multiple days regardless of the expiration/BUD (by use date).
  • You can submit one nonviable form for different NDCs AND for different lot numbers that have the same NDC. You will complete a new line on the form for each of the different lot numbers.
  • You can submit different nonviable reasons all in the same form (you don’t have to separate out expired vaccine from other nonviable reasons). Note that expired COVID vaccines do not get returned like expired VFC vaccines. They should be disposed of as medical waste.
  • You can submit VFC vaccines and COVID vaccines in the same nonviable form.

Even if you need to enter the NDCs and lot numbers manually the above information applies. Remember that vaccine won’t automatically show up in the nonviable screen in MIIC unless it was directly shipped to your site.
