Instead of giving tetanus/diphtheria toxoid and acellular pertussis (Tdap) vaccine to a father-to-be that needed protection against pertussis, we mistakenly gave him tetanus/diphtheria (Td) toxoid. How soon after the Td dose can we give him the dose of Tdap he needs?

There is no minimum period to wait to correct your error. If you had immediately realized that you had mistakenly given the father-to-be Td instead of Tdap, you could have given him the needed Tdap dose at the same visit at which you gave him the erroneous Td dose.
