Immunization (Vaccines)

Immunization is widely recognized as one of the greatest public health achievements of the twentieth century. Vaccines save lives, prevent the spread of diseases and reduce health care costs. Immunization programs are an important foundation of Ontario’s health system. We provide expertise in immunization and vaccine preventable disease.
