There are no mandatory vaccines needed in order to enter Brazil, however you should check your vaccination card before leaving and it might help prevent unwanted surprises.
Yellow fever vaccination before travelling outside and inside Brazil
In São Paulo, most hospitals offer the yellow fever vaccine for free. If you travel to any other countries in South America, custom officials will often ask for proof of vaccination before crossing the Brazilian border.
In 2009, an epidemic of yellow fever struck São Paulo and Rio de Janeiro, so it is better to be safe than sorry.
Prevent yourself from mosquitos and dengue fever in Brazil
Brazil is located in a tropical region characterized by intense heat and a humid climate, which is favourable for mosquito proliferation. Two types of mosquitos found in Brazil are particularily responsible for transmitting dengue fever. This illness can be mortal in some cases especially for little children and elderly people.
Mosquitos tend to reproduce in humid areas where the water is still and so the best way to fight against dengue fever is to remain vigilent for stagnant water and to avoid those areas as best as possible.
Many bug repellent products are available in Brazil, but at night, especially in very humid regions, the use of a mosquito net is highly recommended.
Main vaccines recommended before travelling to Brazil
There is no vaccine to prevent dengue fever. In case of high fever, intense exhaustion, vomitting and apparition of tiny red dots on your body, immediately consult a doctor.
Finally, vaccines for hepatitis A & B, typhoid fever, rabbies and DTP (diphtheria-tetanus-pertussis) are recommended and can be done directly in Brazil.
Just remember, no need to be scared but always be prepared.
