In brief: Yes

It is caused by a nerve toxin produced from certain bacteria usually from contaminated food or improperly processed canned foods.
It can lead to paralysis if untreated. Unfortunately immunity does not necessarily develop. To be safe, canned foods with bulging lids should be thrown out as well as any bulging containers. Or if food has an usual smell it should not be eaten and thrown out as well.

In brief: Yes

After you recover from botulism, it may have been produced by doses of toxin high enough to cause disease, but insufficient to produce antibodies which might prevent reinfection.
There are also different strains of the organism so immunity to one may not confer immunity to other strains.
