A senior Health Canada official removed mention of a “high level of impurity” in mRNA COVID-19 vaccines in an assessment done by a colleague for the department’s chief medical adviser, internal records show.
The assessment was meant as a brief on recent findings about the creation of unintended proteins by mRNA COVID-19 vaccines.
Two senior Health Canada (HC) officials, including the one with final authority on vaccine authorization, expressed concerns about the conclusions written by the HC scientist tasked with producing the assessment.
