Mass vaccination creates healthy oasis in Brazilian city
- 3 years ago
Serrana, a city in southeastern Brazilian state of Sao Paulo, has seen a 95% drop in COVID-19 deaths after it concluded vaccination of almost all adults, TV Globo reported on Sunday.
With 45,000 inhabitants Serrana is a healthy oasis in Brazil, which has the world's second deadliest outbreak with more than 461,000 deaths so far and a very slow immunization pace due to the lack of vaccines.
Serrana was the subject of a study by Instituto Butantan, which produces the Coronavac vaccine developed by China's Sinovac Biotech (SVA.O) in Brazil.
When vaccination was starting, the city had an increase in COVID cases, but the spread of the virus was contained once 75% of the population was immunized, scientists found.
