Brazilian Health Minister Antonio Nardi said the WHO advice stemmed from “an excess of concern”.
Ever since July of last year – when the government declared that the worst wild yellow fever outbreak registered since 1980 had passed – 11 new cases have been confirmed: four fatalities in São Paulo, which registered a total of eight cases, and the states of Minas Gerais, Rio de Janeiro and the Federal District each presented one case of the disease.
Another 92 suspected cases of the disease are being looked into.
The campaign is expected to last fifteen days. The shorter campaign period is part of a strategy to concentrate vaccinations.
