Brazil may be struggling in its battle against the coronavirus, but it is on the cutting edge of vaccine development with large-scale trials and the production of millions of doses on the horizon, according to AFP.

Unlike Europe and China, Covid-19 continues to spread rapidly across the Latin American nation — the second-worst hit country in the world after the United States — creating the necessary conditions for testing a vaccine's efficiency.

The leaders for two of the most advanced vaccine projects — one from Oxford University, in partnership with AstraZeneca labs, and one from China's Sinovac — will carry out Phase Three tests, the last one before the drug is approved, on thousands of Brazilian volunteers.
