Molecular biologist Becky McClain began raising safety concerns in 2000, soon after she started working in Pfizer’s Biosafety Level 2 lab in Connecticut.
Three years later, after management failed to address the issues, McClain was exposed to a genetically modified lentivirus, engineered using gain-of-function technologies that made the virus more infectious and more pathogenic.
The exposure left her disabled, with symptoms including numbness, periodic paralysis, pain and other neurological problems. Doctors couldn’t diagnose or effectively treat her condition because Pfizer refused to disclose what she had been exposed to, citing “trade secrets.”
The incident launched McClain into a decade-long fight to understand her illness and obtain her exposure records so she could seek proper treatment. During her battle, she became a whistleblower, standing up to Pfizer’s threats against her and her family.
