At three tyo four weeks of age your puppy is way too young for vaccinations. He also needs to be with his mommy at that age and still drink milk, Please put him back with his mother or at least raise him properly with puppy milk. If he does not take any food he needs to be seen by a veterinarian, preferably today..
