There was also outcome reporting bias in the mRNA vaccine trials. They only looked at relative risk as opposed to absolute risk. When looking at absolute risk the vaccines had a minimal impact.
"Unreported absolute risk reduction measures of 0.7% and 1.1% for the Pfzier/BioNTech and Moderna vaccines, respectively, are very much lower than the reported relative risk reduction measures. Reporting absolute risk reduction measures is essential to prevent outcome reporting bias in evaluation of COVID-19 vaccine efficacy."
