Since the initial coronavirus outbreak in the U.S. in March 2020, plaintiffs’ lawyers have filed a host of securities class action lawsuits against companies raising a variety of COVID-19-related allegations. Many of these cases have faced significant hurdles at the initial pleading stage, and in a number of cases the dismissal motions have been granted. The one categorical exception to these dismissal motion generalizations seems to be cases involving vaccine development companies. Two rulings in the past week seem to corroborate both of these observations. First, in a December 9, 2022 ruling in the securities suit pending against the diagnostic testing company Talis Biomedical, the court granted the defendants’ motion to dismiss (albeit with leave to amend). However, in a December 12, 2022 ruling in the securities case against the vaccine development company Novavax, the court denied the defendants’ dismissal motion in significant part. The rulings in these two cases are discussed below.

As I have noted in numerous posts on this site, since the initial outbreak of COVID-19 in March 2020, plaintiffs’ lawyers have filed a host of coronavirus-related securities class action lawsuits. As I also noted, the plaintiffs’ track record in these cases has been mixed at best, with a number of the cases being dismissed. In the latest example of the hurdles the plaintiffs are facing in these cases, a federal court has entered an order dismissing the COVID-19 related securities suit that was filed against the pharmaceutical company AstraZeneca relating to the company’s troubled efforts to develop a COVID-19 vaccine. A copy of the September 12, 2022 opinion in the case can be found here.
