AstraZeneca, U. of Oxford Report Positive Phase I/II Data for COVID-19 Vaccine Candidate

Researchers from AstraZeneca, the University of Oxford, and its spinout company Vaccitech today published preliminary Phase I/II data showing their closely-watched COVID-19 vaccine candidate AZD1222 (formerly ChAdOx1 nCoV-19) to have an acceptable safety profile, and favorable immunogenicity against the virus.

“A single dose elicited both humoral and cellular responses against SARS-CoV-2, with a booster immunisation augmenting neutralising antibody titres. The preliminary results of this first-in-human clinical trial supported clinical development progression into ongoing phase 2 and 3 trials,” the researchers concluded in Safety and immunogenicity of the ChAdOx1 nCoV-19 vaccine against SARS-CoV-2: a preliminary report of a phase 1/2, single-blind, randomised controlled trial, published today in The Lancet.
