Oxford University in this weekend started human clinical trials for a potential coronavirus vaccine in Brazil, sponsor Lemann Foundation said in a statement.
Trials will count on 2,000 health workers volunteers in Sao Paulo and 1,000 people in Rio de Janeiro.
Brazil’s health regulator Anvisa approved human clinical trials for this potential vaccine, developed by Oxford and supported by AstraZeneca, earlier in June.
Brazil, where the disease is still rife, is the first country outside the United Kingdom to start testing the Oxford vaccine.
Researchers expect to launch the vaccine by year-end.
