Is it okay for my son to have his first vaccines at 2 and a half months?

My doctor’s office said they have to cancel my son’s first vaccines from two months of age to two and a half months because or conflict with their schedule. I’m just wondering if this is going to back up all his vaccine schedules? Does it matter that he is having them done at two and a half months instead of two months?

I don’t want to hear any comments from anti-vaxxers. I don’t care to hear your opinions.
