# US Vaccination Rates Decline as Exemptions Rise, CDC Data Reveals

Vaccination rates across the United States continue to fall while exemptions climb, according to new data released by the Centers for Disease Control and Prevention. The CDC posted the figures online without publishing a formal report, a departure from its typical reporting format.

The trend reflects ongoing vaccine hesitancy despite years of public health messaging. States have expanded pathways for families to opt out of vaccination requirements, whether through medical, religious, or personal belief exemptions. Some states removed caps on these exemptions, allowing higher percentages of students to enter schools without full immunization records.

The decline affects routine childhood vaccinations beyond COVID-19, including shots for measles, mumps, rubella, polio, and other preventable diseases. Lower vaccination coverage creates conditions for disease outbreaks. Schools with vaccination rates below 85 to 90 percent face increased risk of spreading preventable illnesses.

The CDC's shift to releasing data online rather than through formal reports raises questions about transparency and public awareness. Traditional reports trigger media attention and direct policymakers to address gaps. Online data releases lack that same visibility, potentially allowing troubling trends to spread with less scrutiny.

Public health officials have linked rising exemptions to misinformation campaigns, erosion of institutional trust, and state legislative changes. Some jurisdictions made non-medical exemptions easier to obtain, citing parental choice. Others removed sunset provisions that once required exemption renewals.

The falling rates arrive as the US faces pressure to maintain herd immunity levels for diseases nearly eliminated decades ago. Measles, in particular, poses a reintroduction risk in low-vaccination areas. The disease killed hundreds of Americans annually before vaccine campaigns reduced it to near-zero transmission.

Experts warn that without intervention, preventable disease outbreaks will accelerate. Public health officials continue advocating for
