Is there any cure/vaccination for people who suffer from the cat allergy? No is the answer. There are many people who love cats who are allergic to them. It is very tough. The cat allergy is one of the mysteries of nature because it really does interfere with cat domestication. It makes me wonder if the cat allergy is a modern phenomenon.
Did the people who first domesticated the cat, almost 10,000 years ago, have the same allergy to cats? If so why did they domesticate the wildcat? I guess some people were allergic but not enough to stop domestication progressing.
What percentage of people are allergic to cats? The Asthma and Allergy Foundation of America say that between 15-30% of people with allergies have allergic reactions to cats and dogs. WebMD says that 55% of the American population test positive to one or more allergens. They would seem to be people with allergies. If they are classified like that, then about 10% of US people are allergic to cats and dogs. That is a lot of people and a good number will like cats and like to live with a cat.
There is nothing really solid and workable that allows people with a cat allergy to live with a cat entirely satisfactorily, except that some cats are less likely to cause an allergic reaction. Spayed females are a good start. Whole males are more likely to cause an allergic reaction.
You can wash the allergen off the cat’s fur but he will put it back on again when her grooms himself. And that will be fairly soon after you washed him. In fact it will be immediately afterward.
You can confine your cats to certain areas but what is the point? The Savannah cat is semi-hypoallergenic. What I mean is that the Savannah cat is less likely to cause an allergic reaction.
Why not see if you can adopt a 5th generation female Savannah cat.? That would not be a vaccination for a cat allergy but it would probably be as near as you can get to it. They can be expensive though. I accept that.
Note: the evidence that Savannah cats are somewhat hypoallergenic is anecdotal but the cat created or bought-in by LifeStyle Pets Inc., the Ashera GD, is an F1 Savannah. This company says that their cats are allergy free.
