Hurray for Medium 199

The product insert for Merck's MMR-II vaccine says:
The growth medium for measles and mumps is Medium 199 (a buffered salt solution containing vitamins and amino acids and supplemented with fetal bovine serum) containing SPGA (sucrose, phosphate, glutamate, and recombinant human albumin) as stabilizer and neomycin.

I wonder if this is the same Medium 199, obviously without recombinant human albumin, invented in the late 1940s and absolutely crucial to the development of the Salk Polio vaccine?  I'm pretty sure it is.

And this is a proud story for me, because I live within an hours drive of where medium was invented and the polio virus grown for the Salk vaccine trials of 1954.   Connaught Research Laboratories has been located in a large campus  at the northern edge of Toronto where I've driven by many times.  Many readers will enjoy this link to a short history.  Sooner or later, they've got to get something right.  I just thought it was one building, but it is a whole campus.   Today Connaught is part of Aventis Pasteur and they still do R and D work and vaccine production. I think this is the list of vaccines they make in Toronto.
