The big picture: The study will be in conjunction with Brazil's National Vaccination Program, local health authorities, a hospital and a federal university, Reuters reports.

  • The study will follow the residents for up to one year to see how long vaccine protection lasts, Pfizer said in a statement.

Background: Toledo, which has a population of about 143,000, has already seen 98% of its population take a first dose, and 56% are fully vaccinated, per Reuters.

  • "Here we believe in science and we lament the almost 600,000 deaths from COVID-19 in Brazil," said Beto Lunitti, the town's mayor, at a news conference Wednesday.
