Sinovac Biotech's COVID-19 vaccine candidate triggers immune response

Now, Sinovac Biotech's candidate vaccine, CoronaVac, has been found to induce an immune response in healthy adults aged 18–59 years, 28 days post-vaccination. However, the level of antibodies generated was lower than in people who had recovered from the illness.

Mosaic RBD nanoparticles elicit neutralizing antibodies against SARS-CoV-2

The researchers show that the mice immunized with homotypic or mosaic nanoparticles produced broad binding and neutralizing responses, in contrast to plasma antibodies elicited in humans by SARS-CoV-2 infection. The RBD nanoparticles induced cross-reactive IgG responses in the immunized mice.
