The COVID-19 pandemic has impacted many aspects of health care delivery, including access to routine immunizations for patients of all ages. In infants and toddlers especially, immunizations are essential to preventing vaccine-preventable disease outbreaks.

Feb. 23 is National Kids and Vaccines Day, an occasion that highlights the importance of routine immunizations, as well as COVID-19 and influenza vaccination, to protect children and to promote vaccine confidence.
