Change in percentage of U.S. kindergartners exempt from one or more vaccinations, by jurisdiction, 2021–22 and 2022–23 school years. From the 2019–20 to the 2021–22 school year, national coverage with state-required vaccines among kindergartners declined from 95 percent to approximately 93 percent, ranging from 92.7 percent for diphtheria, tetanus, and acellular pertussis vaccine (DTaP) to 93.1 percent for polio. During the 2022–23 school year, coverage remained near 93 percent for all reported vaccines, ranging from 92.7 percent for DTaP to 93.1 percent for measles, mumps, and rubella and polio. The exemption rate increased 0.4 percentage points to 3.0 percent. Exemptions increased in 41 states, exceeding 5 percent in 10 states. Exemptions >5 percent limit the level of achievable vaccination coverage, which increases the risk for outbreaks of vaccine-preventable diseases. Vaccination before school entry or during provisional enrollment periods could reduce exemptions resulting from barriers to vaccination during the COVID-19 pandemic.

U. S. Black population excess age-adjusted mortality and years of potential life lost rates, 1999-2020. To assess trends over time, the relationship between each metric and study year was graphically assessed, and time was modeled as a linear spline with knots that reflected the observed inflection points from 1999 to 2019. For excess mortality rates, these inflection points were from 2007 to 2011 for males and 2015 for females. For excess rates of years of potential life lost, the knots were 2007 and 2011 for males and 2012 for females. Rates that fall above the dotted line indicate rates higher than the White population and those that fall below, rates lower than the White population. Autoregressive integrated moving average models using a 1-year correlation were implemented to account for the serial correlation of annual rates. The 2019-2020 change was estimated using a z test.
