This is fantastic! Real-world data out of Butantan Institute São Paulo, Brazil shows after ~75% of Serrana’s population had been vaccinated with Coronavac:
•95% reduction in deaths
•86% reduction in hospitalizations
•90% reduction in IC
•80% reduction in symptomatic cases
•95% reduction in deaths
•86% reduction in hospitalizations
•90% reduction in IC
•80% reduction in symptomatic cases
Total vaccinated population: 27,150 (97.7% of adult population vaccinated with first dose; 95% vaccinated with second dose). Keep in mind, this is in the face of variants of concern including P.1. 75% of Serrana’s population had been vaccinated with Coronavac from February-April.
For comparison purposes, Serrana was compared with Jardinópolis, a nearby city. The death curves were similar UNTIL Serrana began vaccinating. After vaccination (first graphic), we can see deaths rose in Jardinópolis (blue) but dropped significantly in Serrana (orange). 
Other important factors to come out of this study: the results showed that vaccination protects not only the adults that received two doses of the vaccine but ALSO children and teenagers younger than 18 years-old who were NOT vaccinated.
Another important conclusion of this study is the incidence of disease in Serrana in comparison with nearby cities. Serrana has around 10,000 residents that work in Ribeirão Preto daily. However, while Ribeirão Preto and other cities within the region are presenting
high levels of COVID-19 cases, Serrana maintained low case numbers when compared to the cities with similar profiles due to vaccination. In other words, the success of vaccination was confirmed not only by the decrease in the number of infected individuals but also for the fact
that residents of Serrana that travel daily from one city to another did not bring a relevant increase to the number of cases! The study also concluded that the last two groups to be vaccinated were already benefiting from the reduction in transmission of the virus generated
by the immunization of the residents of the two first groups! Overall, very encouraging! While we wait for the full study documents, details can be found here: butantan.gov.br/noticias/immun… H/T: @gutoaqui
