Canada is at risk of losing its measles-free status due to a significant outbreak that has spread across provinces, marking one year since the first cases were reported.

Public health experts emphasize the need for improved vaccination efforts and community trust to regain elimination status.

A recent study reveals that approximately 60,000 children have avoided peanut allergies due to a significant change in guidelines issued in 2015, which recommended introducing peanut products to infants as early as four months. This shift has led to a decline in peanut allergies among young children, although overall food allergies in the U.S. continue to rise. Experts emphasize the importance of early allergen introduction and ongoing education for parents and pediatricians.
