Texas Attorney General Sues Pfizer Over COVID-19 Vaccine Efficacy Claims

Pfizer Defends Vaccine Efficacy Claims, Experts Refute Paxton's Arguments

Texas Attorney General Ken Paxton has filed a lawsuit against Pfizer, accusing the company of misrepresenting the efficacy of its COVID-19 vaccine and attempting to censor public discussion about it.
Paxton's lawsuit challenges Pfizer's claim that its vaccine is '95% effective', arguing that this figure refers to the 'relative risk reduction' and not the 'absolute risk reduction'.
Pfizer has responded to the lawsuit, stating that the company's representations about its COVID-19 vaccine have been accurate and science-based, and that they believe the state's case has no merit.
Experts have refuted Paxton's claims, explaining that relative risk reduction is a standard practice for measuring vaccine efficacy as it controls for context-dependent factors, such as infection rates, across different populations.
Official statistics from the Texas Health and Human Services Department show that at every stage of the pandemic and among every age group, vaccinated Texans experienced significantly lower death rates from COVID than the unvaccinated.
