US Vaccination Rates Slip Again as Exemptions Climb, CDC Reports

US vaccination rates trend shows continued decline

The CDC released its latest school‑year snapshot, confirming that US vaccination rates among kindergarteners have slipped for the ninth straight year. In the 2025‑2026 cycle, only 92.4% of children received the measles‑mumps‑rubella shot, a marginal dip from 92.5% ↓ 0.1%. DTaP coverage edged to 92.0% from 92.1% ↓ 0.1%. The downward drift follows a post‑pandemic resurgence of exemption requests, echoing warnings from health officials cited by Reuters. Experts caution that breaching the historic 95 % herd‑immunity threshold could reopen pathways for measles outbreaks, a scenario last seen before the 2019‑2020 peak.
