Can a kitten who has been vaccinated with the feline leukaemia vaccine be contagious with the Feline leukaemia virus and pass it on to an unvaccinated kitten

Vaccination will not cause a cat to be contagious and spread the virus to other cats. The virus is shed in saliva, nasal secretions, urine, feces, and milk of infected cats. Cat-to-cat transfer of the virus may occur from a bite wound, during mutual grooming, and (rarely) through the shared use of litter boxes and feeding dishes. Transmission can also take place from an infected mother cat to her kittens, either before they are born or while they are nursing. FeLV does not survive long outside a cat's body – probably less than a few hours under normal household conditions.
