Let me know what you find out about whether you have to get a new vet certificate in the US prior to returning to Argentina if you've only been out of Argentina for a few days. That would make things much easier for short trips.
I looked online at both SENSA and USDA websites and it appears you don't need any other vaccines for either the US or Argentina. Be careful if you have a layover in a third country. We fly Copa every now and then through Panama and I know Panama has some special requirements.
