Texas may well win. From Brandon Campbell at billkloss.law.blog:

The COVID-19 vaccine was the “miracle that wasn’t,” the “little engine that couldn’t,” and a “job too big for a jab too small.”
After years of waiting for Pfizer to be held accountable in a court of law, justice may be on the horizon for millions who took a shot they thought would keep them from getting COVID-19 and spreading it to others. Just two doses of a 95% effective vaccine with no serious side effects whatsoever, and we were told the COVID-19 pandemic would find its rightful place in our rearview mirror.
In reality, Pfizer’s vaccine is about 0% effective at actually preventing COVID-19 and comes with a wide array of potential side effects that are far worse than COVID-19 itself—such as blood clots, heart damage, and death. But with its clever marketing, an uncanny ability to hide clinical trial data, and federal regulatory agencies in its back pocket, you would never know it.
We all know now—or should know at this point—that Pfizer sold the world a lemon and probably felt that it could because of the expansive amount of immunity it enjoys courtesy of our federal government.
