On Saturday, June 2, 2018, a special symposium was held in honor of Dennis L. Kasper, MD, in his 75th year and celebrating his 45 years of scientific, academic, and administrative accomplishments and his dedicated mentorship of more than 75 fellows and students at Harvard Medical School.

The program's speakers and moderators were Dennis' colleagues, collaborators, and trainees with whom he has had the privilege and great pleasure of working over the course of his career. The symposium was comprised of exciting and cutting edge presentations in the fields of vaccines and the microbiome. The symposium took place in the Joseph B. Martin Conference Center at Harvard Medical School, located in the heart of the Boston Longwood Medical Area.

A reception followed at the nearby Isabella Stewart Gardner Museum, where guests relaxed in the museum's Venetian-style courtyard and surrounding galleries, enjoyed the seasonal buffet, and old friends and colleagues had the opportunity to come together and reminisce. For those guests who wanted to explore some of the museum’s treasures, docents were available in selected galleries.

We thank Dennis’ colleagues, laboratory alumni, current trainees, family, and friends for gathering to participate in this special event. In addition, we thank the Department of Microbiology and Immunobiology at Harvard Medical School for partial support of this event.
