New vaccine design uses immunity against influenza to offer faster protection against emerging pathogens

A new vaccine design has been developed by a UC Riverside-led research team, which uses preexisting immunity to the influenza virus to help kickstart the production of antibodies against SARS-CoV-2. The vaccine aims to speed up the immune response and provide better protection for people who still lack immunity to the coronavirus.
