Measles Vaccination Rates in Pittsburgh Region Drop Below Critical Safety Threshold

Pittsburgh, PA, September 16, 2026 —

Kindergarten vaccination rates for measles in Pittsburgh and Allegheny County have fallen below the 95% benchmark considered essential for community protection against outbreaks. For the 2025-26 school year, the vaccination rate for measles among kindergartners in Allegheny County stands at 91.8%.

This decline is particularly concerning as Pennsylvania is currently experiencing a significant measles outbreak. The drop below the 95% threshold means the region may be more vulnerable to the spread of the highly contagious disease.

The current vaccination figures arrive amidst a challenging period for public health, as the state grapples with an increasing number of measles cases. This situation also brings into focus Pittsburgh’s notable historical contributions to vaccine development, creating a contrast between past innovations and present-day public health challenges.

The specific contractor responsible for reporting these vaccination rates was not provided. Additionally, details regarding the exact number of kindergartners enrolled, the specific schools or districts contributing to the county-wide statistic, or any immediate public health responses planned were not made available in the provided information.

Public health officials typically emphasize that vaccination is a critical tool in preventing the spread of measles. The 95% threshold is widely accepted by health organizations as the level of herd immunity necessary to protect a population, including those who cannot be vaccinated for medical reasons.
