A shareholder has filed a lawsuit against officers and directors of Novavax Inc. on Wednesday, claiming they misled the public about the likelihood of developing and selling a vaccine for COVID-19 to reap millions in personal gains.

Maryland-based Novavax is the second company to be sued in the Court of Chancery for leading investors to believe vaccine testing and production was going better than it was, with similar allegations made 16 months ago against Sorrento Therapeutics Inc.
