Not to mention the size of Gaboons fangs, what's the point in self immunising against such a snake.
One bite, straight into a main vein or artery and you're done for within minutes. Regardless of whether you have self immunised.
Besides, SI is pointless unless its a hazard of your job, like it was with Bill. All these idiots who are doing it at home, aren't doing anything useful. But each to their own.
If it's you or someone you know whose interested, learn to handle Gaboons properly. They're a straight forward snake to handle, it's not hard to avoid a bite if you follow strict protocols and procedure.
