Can DTP booster and typhoid vaccine be given simultaneously?

Question
My five years old son is due for DTP booster and typhoid vaccine. Can these two vaccines be given simultaneously or should we give a gap of four weeks?

They can be safely given at the same time but at two different sites in the body - the two vaccines also should not be mixed. If you do not want to give two injections at the same sitting, then there should be a minimum interval of one month between the two vaccinations.
