Referring to a “peer reviewed study” published in medical journal The Lancet, users on social media have erroneously claimed that the reported efficacy rates for the available COVID-19 vaccines are “deceiving” and that the real rate of protection from immunization is much lower. This stems from a misinterpretation of two different measurements, the relative risk reduction (RRR) and the absolute risk reduction (ARR).
The posts feature a tweet that reads, “@TheLancet peer reviewed study confirms vaccine efficacy, not as 95% stated by the vaccine companies, but as: Astra Zeneca 1.3%, Moderna 1.2%, J&J 1.2% and Pfizer 0.84%. They deceived everyone by reporting Relative Risk Reduction (RRR) rather than Absolute Risk Reduction (ARR).”
Screengrabs of the tweet or posts with virtually the same wording have since spread to Instagram ( here , here , here ) and Facebook ( here , here , here ).
