As I understand it the shots are in the arm now. As for the vaccine you get before exposure to the disease it only gives you a longer period to recieve treatment and reduces the number of injections needed it does not give you long term protection like many vaccines.
The video was disturbing but many diseases are very disturbing in their final stages. Many diseases are even more visually disturbing than rabies when they finally reach their final stages.
As an odd side note does anyone know where I can see a video of Kuru(laughing death)? I know Gajdusek shot a video when he was studying the disease but I have never seen it. I have had a strange yet morbid facination with spongy encephalopathies after reading Deadly Feasts by Rhodes. If anyone knows of a video of this please pass it along to me.
