The COVID-19 mRNA vaccines given to the public weren't those studied in the clinical trials

What does this mean, how did this happen and what next?
In this episode of "Sensibly curious about vaccines", Christine Stabell Benn, MD, PhD and Tracy Beth Høeg, MD, PhD invited Joshua Guetzkow, PhD and Retsef Levi, PhD to talk about what they discovered in relation to the changes in the Pfizer BioNTech COVID-19 vaccine manufacturing process that happened in the fall of 2020. We talk bias and lack of regulatory oversight from the FDA and EMA, what Pfizer may not have disclosed about the vaccine contents, what we know about the contents and safety of the "process 2" batches that the public received, the history of harms from vaccines rolled out with inadequate safety testing, the importance of transparency and how independent research, uncensored discussion and legal actions may offer solutions.
