Do nonvegetarians attract more protection to body than vegetarians?

Do nonvegetarians attract more protection/immunity to body from diseases/infections, especiallly from new ones having no known history (like spread of unknown viruses/bacteria) than vegetarians. I am veg. and always believed that fresh green vegtables coupled with seasonal fruits are the right ingredients for body-defence. Asking the ques in the limelight of being heard that nonveggies taste differnt animals meats - zebra, girafffe, hipoos, alligators, snail, grashoppers, snake, doggies, sheep, pig, etc. in differnt part of world and we all know most of them are carriers to the diseases/sperad of viruses making your body-defence mechanism weak. But if we consume them (as nonveggies), we actually retrain our cells, body mechanism as how to fight new diseases better as its structure is open to our homely body cells for open-reading & understandng, that goes against the veggies as they cant have access to these things in other words they are more prone to fall as victims of disease than nonveggies. Can anybody throw some limelight on this and srry for long ques. Thanks.
