The city of Serrana in Brazil is a living experiment.
The picturesque place, surrounded by sugarcane fields, is nestled in the southeast of one of the countries hit hardest by COVID-19. By the end of March, daily deaths in Brazil surged to 3,000 on average a day, a high in a pandemic that has claimed more than 405,000 lives there the second worst death toll of any country in the world behind only the United States. And as vaccines slowly trickle into the country, only about 15 percent of the population has gotten at least one shot.
Except in Serrana. There, nearly all the adults have gotten their shots. What happens next in this city could provide a glimpse of what the future of the pandemic could be not only in Brazil but across the globe as vaccinations pick up.
