There are even more interesting things happening in Brazil this month, so I decided to write a follow-up to my list from last month. Thanks to several readers who made suggestions about some of these points.
5. Bolsa Família: On October 20, Brazil's renowned conditional cash transfer program turns 10 years old.

4. Dengue vaccine: Instituto Butantan, one of the world's most important biomedical research centers, will begin human trials this month of a dengue vaccine. It was previously tested in the United States, and if results are good, the vaccine could be approved for use in Brazil. Learn more from G1
3. Major oil discovery: Along with the much-anticipated pre-salt auctions taking place in October, the Brazilian government will reportedly announce "the world's largest oil discovery of 2013" next week.
