The Vikings began their raids on Southern Europe and the British Isles in the mid 8th century so they had plenty of time to gain exposure to diseases before the Vinland escapade. If they had contact with Native Americans they would have passed along their microbes. Two things would have happened. A lot of native-americans would have died ( we have no evidence for that) and the survivors would have passed their immunity along to their children and grandchildren and we have no evidence of that either.
So it makes more sense that L'Anse Aux Meadows was more of a temporary camp. It certainly was not well fortified against any sort of attack. Some replicas show a palisade but the question is where did the trees come from because the region looks pretty treeless.

Not much of the way of trees!
