Original Note:
The 1st Hep B vaccine (plasma derived), was tested in several placebo trials. The safer, recombinant vaccine was approved in '87 after comparison studies w/the previous vaccine. When you replace an old vaccine with new the correct trial is old v. new vaccine. https://pubmed.ncbi.nlm.nih.gov/3903646/ https://apps.who.int/iris/handle/10665/264444
