B12 and vegan supply of omega 3 fat is still a concern, especially for children and infants. For example, if you use plant sources for your fat supply of DHA, you'd have to ingest enough ALA to make most people sick. So supplements are necessary for health, especially in children (vegan algae based supplements do exist). Another question is soy reliance. Last I checked, we can reasonably assume that a "normal" amount of soy in a diet is a non issue. However, results during pregnancy and childhood are apparently lacking, and studies in rats show potential problems [1]. "Further investigation is needed before a firm conclusion can be drawn. In the meantime, caution would suggest that perinatal phyto-oestrogen exposure, such as that found in infants feeding on soy-based formula, should be avoided." [2] Just to be clear here: I am a vegetarian. However, I never went full vegan because I think it does require a very mindful and conscious handling of nutrition - and a lot more research [3] By extension, I do not think it is appropriate as a recommendation for the general public at this stage.
