Pennsylvania is battling its deadliest measles outbreak since 1992, with four reported deaths due to complications from the disease. Among the deceased are two newborns, an 18-year-old, and a 40-year-old woman, according to state officials.
In response, health departments in Chester County and the state are implementing strategies to encourage immunisations. This includes nurses like Dale Weiser making home visits to administer vaccines, particularly within the Amish community in rural Pennsylvania, where many individuals do not have regular contact with the medical system.
Since late April, the state health department has administered nearly 4,300 measles, mumps, and rubella (MMR) vaccines at pop-up clinics. Chester County has given 538 MMR vaccines, with 340 administered in private settings, including homes.
The outbreak has also highlighted political tensions, with Health Secretary Robert F Kennedy Jr reportedly disputing at least one of the infant deaths. Democratic Governor Josh Shapiro has criticised Kennedy, stating he is spreading misinformation.
