Texas Attorney General Ken Paxton is suing Pfizer, alleging that the pharmaceutical giant lied about the effectiveness of its COVID-19 vaccine.

In a press release obtained by Fox News Digital, Paxton’s office accused Pfizer of "unlawfully misrepresenting the effectiveness of the company’s COVID-19 vaccine and attempting to censor public discussion of the product."

Paxton’s office said Pfizer’s claim that its vaccine possessed 95% efficacy against infection was "highly misleading." 

FOX Business has reached out to Pfizer for a response.
