Brazil, where the number of cases has now surpassed 2 million, is one of a small handful of sites for testing experimental coronavirus vaccines. It offers an unusual and appealing mix for research: a skyrocketing rate of transmission, as well as internationally respected research centers and a public health system experienced in creating and distributing vaccines.
According to the World Health Organization, as of July 14, 163 Covid-19 vaccines were being developed around the world, and 23 of them had started clinical trials involving humans. But only two have reached Phase 3 — the last scientific stage before approval to be marketed — which requires large-scale trials with thousands of individuals to assess the efficacy and safety of the vaccine.
Both Phase 3 trials will include Brazil and are scheduled to involve at least 14,000 Brazilians. Advanced talks are also underway to launch three more vaccine trials in the country, according to Brazilian institutes consulted by CNN.
