Zydus Cadila has finished a phase 1 clinical trial of its COVID-19 vaccine ZyCoV-D, setting it up to move straight into a 1,000-subject phase 2 study. By ordering human cells to make the protein, ZyCoV-D could cause an immuneresponse against the coronavirus.
The results suggest that the REGEN-COV (casirivimab/imdevimab) antibody could play a key role in protecting people who do not mount a sufficiently strong immuneresponse after COVID-19 vaccines, according to the company.
