Pfizer has announced a plan to fully immunize an entire Brazilian city to study the long-term effects and safety of its COVID-19 vaccine in a “real world” scenario.
The one-year study will simulate a situation in which anyone aged 12 and over is fully vaccinated with Pfizer-BioNTech serum. He will closely monitor the duration of the vaccine’s effectiveness and how it works against newer variants, according to the New York Times.
The study will take place in the Brazilian city of Toledo, where 98 percent of the population is vaccinated. It will be carried out by a hospital, university and local health officials, as well as in correlation with Brazil’s national immunization program, the Times reported.
“Here we believe in science and we deplore the nearly 600,000 deaths from Covid-19 in Brazil,” Toledo Mayor Beto Lunitti said when announcing the study, according to the Times.
Another Brazilian city called Serrana is said to be the site of the first mass trial of the COVID-19 vaccine. This trial was successful in reducing new cases, hospitalizations and deaths in the city by 45,000 people.
Brazil as a whole has suffered a particularly high death toll, however, as its president, Jair Bolsanaro, has publicly questioned COVID-19 vaccinations and other public health measures.
After the United States, Brazil was only the second country to pass the milestone of 600,000 deaths.
The Hill contacted Pfizer for more information.
