The latest Twitter Files involving the tech giant's response to the pandemic puts a focus on Dr. Scott Gottlieb, a former FDA commissioner and sitting board member of prominent COVID vaccine manufacture Pfizer. 

Alex Berenson, a vocal COVID contrarian whose past commentary on the vaccine has received scorn by critics and praise by fans, was the latest to be granted access to Elon Musk's Twitter Files, publishing his findings on his "Unreported Truths" Substack newsletter. 

Berenson shared an August 2021 email Gottlieb sent to Twitter's senior public policy manager Todd O’Boyle flagging a tweet written by former Trump administration official Dr. Brett Giroir, who had written "It's now clear #COVID19 natural immunity is superior to #vaccine immunity, by ALOT. There's no scientific justification for #vax proof if a person had prior infection."

"This is the kind of stuff that's corrosive," Gottlieb told O'Boyle. "Here he draws a sweeping conclusion off a single retrospective study in Israel that hasn't been peer reviewed. But this tweet will end up going viral and driving news coverage."
