Vial of Connaught Medical Research Laboratories’ combined DPT-polio vaccine.

Connaught Medical Research Laboratories were instrumental in the development of the polio vaccine, first by developing a culturing medium, then by producing the mass quantities of polio virus cultures required to carry out Dr. Jonas Salk’s vaccine trials in the Unites States and Canada in the mid-1950s.

This vial was produced by the lab in 1970, and shows the addition of diphtheria and tetanus toxoids and pertussis vaccine to reduce the number of shots required.

In 2002, this artifact was added to the Ingenium collection.
