CDC Updates Guidance for COVID-19 and Chickenpox Vaccines

The Centers for Disease Control and Prevention (CDC) recently updated its guidance for the COVID-19 and varicella (chickenpox) vaccines. The CDC’s decision uses an individual-based decision-making framework, referring to vaccination decisions made through shared clinical decision-making. The framework notes that vaccination should be determined based on patient characteristics, which can make broad-based recommendations difficult to apply.

The U.S. Food and Drug Administration approved marketing authorization for the COVID-19 vaccine to include those 65 and older and people at high risk for developing severe illness from the virus. This is in contradiction to policy in the past years, which recommended the vaccine for everyone six months and older.

The CDC also recommends updating the immunization schedule for chickenpox to be a standalone immunization rather than given in combination with the measles, mumps and rubella vaccines. This guidance is informed by evidence provided by the CDC Immunization Safety Office that states “Healthy 12–23 months old toddlers have an increased risk of febrile seizures seven to ten days after vaccination for the combined measles, mumps, rubella and varicella vaccine compared to those given immunization for chickenpox separately.”

The CDC stated that this change in decision making will continue to cover immunizations through payment systems that include Medicare, Medicaid, Children’s Health Insurance Program, the Vaccines for Children Program and private insurance plans.

State’s Chief Medical Executive Issues Standing Recommendation for COVID-19 Vaccine Access

Michigan’s Chief Medical Executive, Dr. Natasha Bagdasarian, issued a Standing Recommendation on Sept. 19 that expands eligibility for COVID-19 vaccines, ensuring access for all residents six months and older.

The recommendation follows Executive Directive 2025-7 from Governor Gretchen Whitmer, which requires state agencies to ensure broad access to Covid-19 vaccines. Gov. Whitmer calls on the Michigan Department of Health and human Services (MDHHS) and other state agencies to:

  • Issue clear guidance on vaccine safety and efficacy.
  • Encourage prescribing and administering COVID-19 vaccines to eligible populations
  • Identify and remove obstacles to ensure vaccines remain widely available across Michigan.

Under federal approval, the U.S. Food and Drug Administration (FDA) authorized the 2025-2026 COVID-19 vaccines for individuals 65 and older, and those ages 5-64 with at least one underlying condition that puts them at a higher risk. However, the FDQ did not define qualifying conditions. The Centers for Disease Control and Prevention (CDC) maintains a non-exhaustive list, including obesity and physical inactivity, but warns against excluding people from access.

Dr. Bagdasarian’s order clarifies that anyone six months or older who has not received a 2025-2026 vaccine dose may be considered to have a qualifying condition and is therefore eligible for vaccination.

The MDHHS continues to recommend vaccination in alignment with federal and medical guidelines. MDHHS is also working with the Department of Insurance and Financial Services and the Department of Licensing and Regulatory Affairs to ensure vaccines remain widely available and covered by insurance.

In addition, the Michigan chapter of the American College of Physicians (MI-ACP) and MDHHS hosted a joint webinar, “From Policy to Practice: What Internists Need to Know About the Latest Vaccine Recommendations,” on Sept. 11. Dr. Bagdasarian and Dr. Romesh Nalliah, associate dean for patient services at the University of Michigan School of Dentistry, presented to internal medicine physicians on COVID-19 vaccine guidance, potential changes to insurance coverage and availability.

Providers are encouraged to continue emphasizing the safety and effectiveness of vaccines to their patients and communities.

Vaccination Resources Available for Healthcare Providers

The MHA remains committed to supporting vaccination efforts across the state by providing healthcare professionals with timely resources, updated guidance and tools to strengthen public health outreach.

The state of Michigan has reported 18 measles cases and 855 pertussis cases so far in 2025, reinforcing the critical role of routine vaccinations and the need for clear, consistent guidance for providers.

The following tools are available to help strengthen vaccine outreach and support on-time immunizations:

  • The Citizens Research Council of Michigan released a new vaccine report, which highlights recent changes to federal vaccine recommendations and provides policy recommendations to strengthen vaccination efforts statewide.
  • The Centers for Disease Control and Prevention (CDC) has updated it’s Be Ready for Measles Toolkit, which now includes adult MMR vaccination decision trees, summer camp checklists and immunity record templates. Recent CDC data confirms 1,197 measles cases across 34 states and 90% of which are linked to outbreaks. Of these cases, 95% occurred in individuals who were unvaccinated or had unknown vaccination status.
  • The July 14 I Vaccinate newsletter includes new provider resources and Q&A materials to support vaccine-related conversations with patients and families.

The MHA continues to work closely with the MDHHS Division of Immunizations and other partners to promote consistent vaccine messaging and improve vaccination rates across Michigan.
