Is it acceptable to use comma after 'and'. I have seen this in scientific papers. e.g. Both Type I and, Type II diabetes need equal attention.
It looks strange to me and I haven't seen it in the meaning from your example. In some sentences a comma may be used ("Type I and, as I have already mentioned, Type II diabetes ..."), but this is a different situation. I think that there is a mistake in your exemplary sentence, but I'd like to learn the teachers' opinion. Let's wait for that.
