On 2 June, the Brazilian Health Regulatory Agency (ANVISA) approved the inclusion of Brazil in the clinical trials conducted by Oxford University and supported by AstraZeneca, considering 2,000 volunteers to be tested in the country.

On April 30, the University of Oxford and AstraZeneca announced an agreement for the global development and distribution of the University’s potential recombinant adenovirus vaccine aimed at preventing COVID-19 infection from SARS-CoV-2.

A Phase I/II clinical trial of the Oxford vaccine began in April in the UK to assess safety and immune response in over 1,000 healthy volunteers aged 18 to 55 years across several trial centres in southern England. As the vaccine trials move to Phase III a larger population is being enrolled consisting of 10,000 participants in the UK with AstraZeneca enrolling 30,000 particpants in the US. On 2 June, the Brazilian Health Regulatory Agency (ANVISA) approved the inclusion of Brazil in the clinical trials conducted by Oxford University and supported by AstraZeneca, considering 2,000 volunteers to be tested in the country. 

Professor Andrew Pollard, Chief investigator of the Oxford Vaccine Trial at Oxford University said: “We are delighted to be working with the talented team of investigators in Brazil on the COVID19 vaccine trial, as researchers and scientists around the world collaborate on clinical development work with unprecedented urgency to combat the global threat to human health that is coronavirus.”
