Re: Covid-19: Researcher blows the whistle on data integrity issues in Pfizer’s vaccine trial

Dear Editor,
Dear Mr.Thacker,

A few days ago I made a post on my Facebook profile and quoted and linked your article.

Today I was notified by Facebook that the post had received a warning flag as “independent fact checkers” had found major faults and lack of evidence in the BMJ article.
Here is the “fact check”:

I looked into it and my impression is that the counter arguments are very superficial: it was to be expected that Pfizer denies the issues uncovered by the report. That’s the first reaction of such players in any case of fraud, misbehavior or similar accusations.

I just wanted you to know about the warning label because it is very likely that this will have happened in other cases as well where people are spreading your report. Maybe you have the chance to contact Facebook about it or cover the issue in a follow-up report.

Thanks for your work and all the best!
