Novavax Covid-19 vaccine induces immune response in early study


Novavax Inc mentioned on Tuesday its experimental Covid-19 vaccine produced excessive ranges of antibodies towards the novel coronavirus, in accordance with preliminary information from a small, early-stage scientific trial, sending the corporate’s shares up 10%.
