SERRANA, Brazil—As Covid-19 has raged across Brazil, killing nearly a quarter of a million people, high infection rates have turned the country into the perfect testing ground for vaccines.
Now, Brazil is using its misfortune to help answer one of the pandemic’s most pressing questions as millions are being inoculated world-wide: Can someone who is vaccinated still transmit the virus?
In the first experiment of its kind globally, researchers Wednesday began a project to vaccinate the entire adult population of Serrana, a hard-hit commuter town of 45,000 people in São Paulo state, before the rest of the country.
