Proximity to nuclear power plants was associated with elevated mortality from breast, colon, and lung cancers. From 2000 to 2020, an estimated 39,767 female deaths (95% CI: 9312–69,381), representing 2.01% (95% CI: 0.47–3.50%), and 38,124 male deaths (95% CI: 16,106–59,600), representing 2.33% (95% CI: 0.98–3.64%), were attributable to this proximity. Lung cancer accounted for the largest burden in both sexes, followed by breast and colon cancer in females and colon cancer in males. Mortality risks declined with increasing distance, becoming negligible beyond 50 km.

Immunizations against Covid-19, RSV, and influenza have shown consistent effectiveness and safety and are associated with a substantially reduced risk of hospitalization and severe disease across populations. Findings from a @CIDRAP systematic review underscore the enduring value of immunization against respiratory viruses as a cornerstone of preventive care and support the feasibility of maintaining rigorous, evidence-based guidance during periods of institutional disruption.
