Authors' response to Letters to the Editor re: Clinical public health: harnessing the best of both worlds in sickness and in health.

We are pleased that our paper on clinical public health1 received support from Dr. Shah,2 who also provides important historical aspects of clinical public health. Dr. Shah was the inaugural director of a newly created residency program (Community Medicine, now known as Public Health and Preventive Medicine) at the University of Toronto in 1976. Although he claims to have failed to “bring clinicians and public health professionals together to define the common elements and synergy needed,”2 we believe he did not fail, because his efforts ignited sparks among his students (including several co-authors of this paper1). Building on his important legacy, subsequent generations of clinicians and public health professionals have made strides towards effective collaboration of clinical medicine and public health.
