Each Wonks’ Corner, a Blue Shield leader dives into a current policy topic. See our previous Wonks’ Corner blogs here.

News of major changes to federal vaccine policy have patients, stakeholders and members asking what it all means for their coverage and care – especially for their children. Blue Shield of California is committed to protecting patient access to vaccinations as one of the most effective interventions available against the spread of infectious disease. Dr. Ravi Kavasery, M.D., Blue Shield of California’s Senior Vice President and Chief Medical Officer, explains in our Wonk’s Corner how we are partnering with public and private stakeholders to ensure science drives vaccine care and coverage decisions.

Vaccines remain one of the most effective and cost-efficient public health interventions, preventing millions of deaths annually and reducing the burden of infectious disease across populations. However, in a time of growing skepticism and confusion over the safety and efficacy of vaccines, childhood vaccination rates continue to decline.

In recent weeks, the Centers for Disease Control and Prevention's (CDC) advisory committee voted to narrow recommendations for pediatric Hepatitis B vaccinations, the U.S. Food and Drug Administration (FDA) pledged to impose sweeping new approval requirements, and Health & Human Services (HHS) Secretary Robert F. Kennedy, Jr., is also reportedly considering changes to the federal program that compensates patients for vaccine injuries that could affect manufacturers’ market participation decisions.

As a practicing physician and as Chief Medical Officer at Blue Shield of California, I recognize the unique position of payers to be public health actors with the capacity and responsibility to encourage vaccinations, protect evidence-based scientific integrity, and collaborate across sectors to increase uptake. In partnership with private and public stakeholders, Blue Shield is prioritizing a few key areas for members and patients:

Ensuring Access

  • Vaccinations should be universally accessible, regardless of a person's insurance type, geography or socioeconomic status. Blue Shield of California was among the first health plans to commit to continuing coverage for evidence-based vaccines with no-cost sharing for members.
  • Major health plans are voluntarily covering evidence-based vaccines throughout all of 2026 and California law is stepping in to preserve that coverage and access irrespective of federal uncertainty.
  • Health plans can leverage population-level data to identify gaps in vaccination rates and deploy interventions to reach high-risk individuals and communities.

Evidence-Based Decisions

  • As public trust in vaccines and public health institutions erodes, it is critical that we base coverage decisions on independent, evidence-based guidance, ensuring that coverage decisions reflect the best and most current available data.
  • Alignment between regulatory guidance and health plan coverage minimizes confusion for patients and providers and reinforces credibility in public health messaging. Blue Shield of California is proud to partner with the California Department of Public Health on maintaining science-based coverage for vaccines in concurrence with the West Coast Health Alliance, a partnership between California, Washington, Oregon, and Hawaii to provide unified, science-based recommendations on immunizations.

Industry Collaboration

  • Clinicians and pharmacists remain the most trusted source for vaccine information. Health plans can support their work by streamlining reimbursement, reducing administrative burdens, and investing in provider education.
  • Blue Shield of California is a member of the Common Health Coalition, which is working to improve coordination across provider, payer, and public health organizations to translate the science-backed evidence on vaccines into sound policy and action for patients.

Health plans have a unique and critical role to play in creating a strong public health infrastructure. Blue Shield of California is committed to working alongside government and industry stakeholders to ensure ongoing coverage and access to preventive, evidence-based care, including immunizations.
