Pine Bluff letter OPINION | LETTER TO THE EDITOR: Look deeper at vaccine's history by Special to The Commercial | Today at 2:42 a.m. Look deeper at vaccine's history Editor, The Commercial, I want to express my appreciation to Byron Tate for his excellent report on the virus and vaccines in Monday's issue. He quoted Dr. Scott Winston of Sheridan, a medical doctor of good repute locally. It was all factual; I had checked all of it out some time ago. But they couldn't print all the known facts and development history of the mRNA method and processes used in its manufacture and testing.
