You rarely hear about what goes on behind the scenes when it comes to drugmakers and their efforts to defend their moneymaking products as safe and effective.

Sunday on Full Measure, a special Full Measure interview two decades in the making.

We’ll hear from a scientist who worked as a virologist inside Merck when he was assigned to a project called Protocol 007 and turned into a whistleblower.

Protocol 007 was part of an effort at the vaccine maker to prove that flaws discovered in its MMR vaccine could be addressed without recalling the product.

Wait until you hear what this scientist says he discovered. It involves allegations of Merck managers ordering the falsification of records to protect the vaccine when tests showed it wasn’t performing properly.

Merck denies doing anything improper.

Also Sunday, Lisa Fletcher reports on New York City’s interesting history of vigilantism on the subway system.

Fears of riders in the absence of a strong police presence have inspired four decades of high profile figures who took matters into their own hands to protect themselves or the public.

And Scott Thuman will show give us a breathtaking glimpse of worst case scenario survival training underwater.

See you Sunday!
