I am not sure about vegan diet but I have many friends who have been vegetarians(include dairy products in their food) their whole life and are healthy. Have never heard of a link between being vegetarian and vitamin deficiency. I presume as long as we eat a wide variety of vegetables and lentils, it should be fine. NHS seems to support the case as well:

I believe cutting back on meat would still be a significant improvement over the current situation.
