Updated mRNA COVID-19 Vaccines Targeted for Recent Subvariants

The Food and Drug Administration approved the updated mRNA COVID-19 vaccines from Pfizer-BioNTech and Moderna Sept. 11. These updated vaccines currently target circulating subvariants including XBB.1.5, EG.5 and FL.1.5.1, as well as BA.2.86, and provide improved protection against severe outcomes such as hospitalization and death.

The Centers for Disease Control and Prevention (CDC) convened its Advisory Committee on Immunization Practices Sept. 12, which issued recommendations about vaccination administration, dosing and scheduling. The final recommendation is that everyone six months of age and older should receive an updated COVID-19 vaccine this fall, ensuring it has been at least two months since receipt of the last COVID-19 vaccine dose.

Additional vaccination guidelines include:

  • Individuals six months – four years:
    • Complete a multi-dose initial series (two doses of Moderna or three doses of Pfizer) with at least one dose of the updated 2023-2024 vaccine.
    • If the initial series is already complete, 2023-2024 vaccine can be issued at least two months after receipt of last COVID-19 vaccine dose.
  • Individuals five years of age and older:
    • Regardless of prior vaccination, receive one dose of the updated 2023-2024 COVID-19 vaccine at least two months after receipt of last COVID-19 vaccine dose.
  • Individuals who are moderate or severely immunocompromised:
    • Complete a three-dose initial series with at least one dose of the updated 2023-2024 COVID-19 vaccine.
    • Individuals may receive one or more additional COVID-19 vaccine doses.

Additional details are forthcoming and will be provided in CDC’s Interim Clinical Considerations.

Per the CDC, COVID-19 and flu vaccines may be coadministered, which may be an effective strategy to ensure broad vaccination coverage for all eligible Michiganders.

The U.S. Government ended distribution of COVID-19 vaccines through the current ordering system Sept. 12.

Updated vaccines can now be ordered:

Please note that Bivalent mRNA (Pfizer-BioNTech or Moderna) COVID-19 vaccines are no longer authorized for use in the United States. It is recommended providers remove all bivalent mRNA COVID-19 vaccines from storage units and dispose of them immediately, in accordance with local, state and federal regulations.

The MHA continues to keep members apprised of pandemic-related developments affecting hospitals through email updates and the MHA Coronavirus webpage. Important updates are outlined below.

Governor Signs COVID-19 Liability Legislation

Gov. Gretchen Whitmer recently signed several COVID-19 liability-related bills:

  • House Bill 5244 (Public Act 138 of 2022) amends Public Act 238 of 2020, which prohibits an employer from taking certain actions against an employee who does not report to work under circumstances related to COVID-19, to specify that the Act would not apply to a claim or cause of action that accrued after July 1, 2022. In addition, the bill will repeal PA 238 of 2020 effective July 1, 2023. HB 5244 was sponsored by Rep. Andrew Fink (R-Hillsdale).
  • House Bill 6128 (Public Act 140 of 2022) amends Section 85 of the Michigan Occupational Safety and Health Act to specify that certain conditions establishing immunity for employers whose employees were exposed to COVID-19 would not apply to an exposure that occurred after July 1, 2022. In addition, the bill would repeal Section 85 and Section 85a, which defines COVID-19 under the Act, effective July 1, 2023. HB 6128 was sponsored by Rep. Yousef Rabhi (D-Ann Arbor).
  • House Bill 6215 (Public Act 139 of 2022) amends the COVID-19 Response and Reopening Liability Assurance Act to specify that the Act, which provides immunity to a person that acts in compliance with certain federal, state and local orders related to COVID-19, would not apply to a claim or cause of action that accrued after July 1, 2022. In addition, the bill would repeal the Act effective July 1, 2023. House Bill 6215 was sponsored by Rep. Graham Filler (R-DeWitt).

Novavax Vaccine Gets FDA Authorization

The Food and Drug Administration (FDA) granted emergency use authorization to Novavax’s COVID-19 vaccine July 13. The vaccine is a two-dose series administered three weeks apart and uses a different, older vaccine technology than is used in the messenger RNA vaccines and Johnson & Johnson shot.

Novavax’s vaccine is authorized for people ages 18 and older as a primary series. It may be appealing to those adults who were hesitant to receive another brand of vaccine due to the components or development process.

In a trial of more than 26,000 adults, two doses of the Novavax COVID-19 vaccine were more than 90 percent effective at preventing symptomatic disease. For adults 65 and older, effectiveness was more than 78 percent. There were no serious side effects or safety concerns.

The Centers for Disease Control and Prevention (CDC) will next decide whether it will endorse the vaccine. The CDC Advisory Committee on Immunization Practices will meet July 19, though an agenda is not yet available.

The Biden administration recently announced that it had purchased 3.2 million doses of the Novavax vaccine. If the vaccine is recommended by the CDC, it will be made available at no cost to states, jurisdictions, federal pharmacy partners and federally qualified health centers. The MHA will keep members apprised of vaccine availability and ordering processes at the appropriate time. Members with questions may contact Ruthanne Sudderth at the MHA.

Children Ages Six Months Through Five Years Eligible for COVID-19 Vaccine

The Michigan Department of Health and Human Services (MDHHS) announced June 21 that all Michiganders ages six months and up are now eligible for a COVID-19 vaccine. The pediatric vaccine, which received emergency use authorization for this age group from the Food and Drug Administration, was recommended by the Centers for Disease Control and Prevention’s (CDC) Advisory Committee on Immunization Practices June 18. The MHA released a media statement following the CDC recommendation, which makes 500,000 more Michigan children eligible for vaccination.

The MDHHS is recommending providers begin vaccinating children ages six months and older as soon as possible. The Moderna series is two doses given 28 days apart for ages six months through five years. For children six months of age through four years, the Pfizer series is three doses, with the first two given three weeks apart and the third dose administered at least eight weeks after the second dose. For ages five and older, the Pfizer series is two doses given 21 days apart.

In addition, the CDC has issued important updates to the Interim Clinical Considerations for Use of COVID-19 Vaccines Currently Approved or Authorized in the United States. The MDHHS has provided an outline of the updates. The updates are outlined in the attached communication from MDHHS.

Questions about COVID-19 vaccines should be directed to Ruthanne Sudderth at the MHA.
