Since 1967, Dr Tayot spent twenty years in the R&D division of Institut Mérieux (now: Sanofi Pasteur). He played a leading role in the development and scale-up of purification and production technologies in vaccines, blood and placental products.

  • Symatèse, a subsidiary of Laboratoires Pérouse specialised in biopolymers;
  • Imedex Biomatériaux, a division of Sofradim, now a Covidien company;

He also collaborated with the Genzyme founders, to extract the placental glucocerebrosidase at the origin of Ceredase® for the therapy of the Gaucher’s disease.
