The scientist who ushered Pfizer’s COVID vaccines through the regulatory process is retiring. Announced today.

This follows the loss of the CFO’s of Moderna and Pfizer (there replacements were both announced in April) and the loss late in 2021 of two of FDA’s top vaccine regulators, Marion Gruber and Philip Krause.

Kathrin Jansen, the leader of Pfizer’s
vaccine R&D group, has decided to retire, the company’s Chief
Scientific Officer Mikael Dolsten said in a LinkedIn post. The company plans to conduct a search for her replacement and will name a successor afterward, he said.

There are so many song titles these stories bring to mind.

Take the Money and Run

The Times They Are A Changin’

and, while not a propos to Ms. Jansen’s situation, it is a jingle that goes through my head often:  Won’t Get Fooled Again
