Yes, all those you need at home and a few more to stay healthy in Brazil, especially a Yellow Fever vaccination. Without the certificate of Yellow Fever vaccination, you will not be allowed to travel on to some other countries. If you are over the age of 60, or you cannot have the vaccination for other reason, it is likely your doctor will be able to issue you with an exception. Then you bring that exemption instead of the certificate along with you. For visits to the Amazon, malaria prophylaxis is highly recommended as well.
Your travel consultants can steer you into the right direction, but ultimately only your doctor using current information from the World Health Organization and the Centers for Disease Control can decide. In case anything happens to you, you will (as a foreigner) always be taken to the nearest private hospital. All private hospitals deliver comparable care to your hospitals at home. In case of tropical diseases, they are much better prepared!
