Thousands are vaccinated for yellow fever in Brazil

Health authorities in Brazil have closed 15 parks in the country's biggest city after a dead monkey infected with yellow fever was found in one of them.
Sao Paulo State Health Department David Uip told Jovem Pan radio station today that closing the parks is a preventive measure.
All of the parks are located on the city's north side, where close to 13,000 people have been vaccinated for yellow fever since a vaccination campaign was launched last week.
Less than two months ago, Brazil declared an end to a yellow fever outbreak that infected 777 people and killed 250 during the first nine months of this year.
