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.

Map of ensemble mean trends in ocean temperature and ice-shelf basal melting in the West Antarctic Ice Sheet (WAIS) for the Paris 2°C scenario. Temperature is averaged over the depth range 200–700 m. Trends are calculated at each point using annually averaged fields from 2006–2100. White regions indicate no significant trend. The Amundsen Sea region visualized here (latitude–longitude projection) is outlined in red in the inset map of Antarctica (polar stereographic projection). The black dashed line shows the 1,750 m depth contour of the continental shelf break and the blue dashed line outlines the continental shelf region used for analysis. Labels denote ice shelves (G, Getz; D, Dotson; Cr, Crosson; T, Thwaites; P, Pine Island; Co, Cosgrove; A, Abbot). Graphic: Naughten, et al., 2023 / Nature

Geographical pattern of the primary drivers of deteriorating status among amphibians. a,b, The primary drivers of deteriorating status among amphibians during 1980–2004 (482 species; a) and 2004–2022 (306 species; b). Cell colour was determined by the primary driver impacting the most species. Where two primary drivers equally contribute to a cell, an intermediate colour is shown.
