Public is Less Optimistic and More Frustrated with State of Vaccinations Now Than in January Nearly a quarter (23%) of fully vaccinated adults have already received a COVID-19 booster shot, more than double the share who had done so in October (10%), the latest KFF COVID-19 Vaccine Monitor report reveals.
As states expand COVID-19 vaccination efforts to reach newly eligible children ages 5 to 11, a new KFF analysis highlights several tools state Medicaid programs have at their disposal to increase access to, and take up of, vaccines among lower-income children.
Following the recent US Food & Drug Administration’s (FDA) authorization and the Centers for Disease Control and Prevention’s (CDC) recommendation, children ages 5-11 are now eligible to receive Pfizer-BioNTech’s COVID-19 vaccine.

State Medicaid programs and Medicaid managed care plans are looking at a range of policy options to facilitate access to vaccines for young, low-income children.
