(Reuters) - Pfizer has been sued by Texas Attorney General Ken Paxton, who on Thursday accused the drugmaker of misrepresenting the efficacy of its widely-used COVID-19 vaccine.
In a complaint filed in a Lubbock County state court, Paxton said it was misleading for Pfizer to claim its vaccine was 95% effective because it offered a "relative risk reduction" for people to who took it.
Paxton said the claim was based on only two months of clinical trial data, and vaccine recipients' "absolute risk reduction" showed that the vaccine was just 0.85% effective.
He also said the pandemic got worse even after people started taking the vaccine, developed by Pfizer and its German partner BioNTech.
"Pfizer intentionally misrepresented the efficacy of its COVID-19 vaccine and censored persons who threatened to disseminate the truth in order to facilitate fast adoption of the product and expand its commercial opportunity," the complaint said.
