Then I apologise for misinterpreting your intent.
I was correcting a word, not the grammar.
I think it could be argued either way, actually, but this isn't really
the place to conduct such a debate.
My
intent was to help the OP with a common English mistake, not flame.
When I was at school, we were told never to precede and with a comma.
When I was at school, we were told that 1 is prime. That doesn't mean I
have to believe it, and I'm sure you'd be the first to agree.
The omission of a comma after 'and' is to do with lists:
"Chris, the other Chris, Steve and Keith are all highly respected
regular contributors to comp.lang.c."
Even there, the comma is optional. If used, it is known as the "Oxford
comma":
"Chris, the other Chris, Steve, and Keith are all highly respected
regular contributors to comp.lang.c."
When 'and' is being used as a conjunction, it often makes sense (but not
always) to use a comma just before it, and I hope this sentence gives
you a good example of that fact.
