immune system of premature baby compared to a term baby?

At what age does a normal term baby fully establish its immune system? I don’t know why but I have 3 months in my head but babies get their 6 week immunisations, so is it more of a gradual build up?
And does this same theory apply to a premie baby from it’s actual due date OR is it from the date of its predicted due date?

Baby has thymus near rib cage weighs 30gms becomes 3 gms by adult hood. Means immunity does not develop overnight. It is gradual and grows on opportunity. Immunity keeps maturing, differentiating continuously through out the life. Immunisation is only a program designed at appropriate age where the kind of immunity is sufficiently strong enough to build immunity against that diesease.
You can say approximately 5-7 years maximum immunity would have been developed. No clear idea about prmie baby, may be immunity is not linked to premie, then it should be on track from the moment it gets exposed to atmosphere. Only first hour of life we may be sterile, then we house billions of microbes.
at birth a normal infant’s immune system is capable of functioning effectively. plus they have added protection from antibodies they get from their mother. this protection lasts for the first couple of months. vaccines are just something to “fool” the body into thinking its dealing with an infection so it can develop a response to it. it can only work if the immune system is functioning.
about the second part of your question, premature babies have less developed immune systems.
