On 14 July 2021, Brazil's National Health Surveillance Agency (ANVISA) reported that it had authorized a clinical trial of AstraZeneca's COVID-19 vaccine candidate, identified as AZD2816, developed with the same technology as the AZD1222 vaccine, designated as ChAdOx1 nCoV-19.

The AZD2816 vaccine candidate is a new version of the currently available ChAdOx1 nCoV-19 vaccine, which has been modified to also provide immunity against the new emerging strain of the Beta variant (B.1.351) of SARS-CoV2, first identified in South Africa.

The phase II/III, partially double-blind, randomized, multinational, controlled study will be conducted in adults 18 years of age and older to determine the safety and immunogenicity of the AZD2816 vaccine candidate, when administered as a third dose in individuals who previously received two doses of the ChAdOx1 nCoV-19 vaccine or two doses of an mRNA COVID-19 vaccine; as a 2-dose primary homologous vaccine for unvaccinated individuals; and as the second dose of a 2-dose primary heterologous vaccination regimen, with ChAdOx1 nCoV-19 as the first dose and the candidate vaccine as the second dose.
