***Speak to a medical professional***
If you're living permanently in a malaria risk area (and Vung Tau may not be - most of coastal VN isn't), speak to your doctor about Malarone, if they don't mention it themselves that is.
More common (and much cheaper I might add) drugs like doxycycline and lariam you must take every day for prophylaxis. It's not ideal to be taking antibiotics long term as your body and the local mosquito popultaion build up a resistance to them. With Malarone you can keep some pills handy and then just take a heap if you start exhibiting symptoms - though same as the other anti-malarial drugs, it doesn't prevent malaria, it just gives you more time to get treated. Unfortunately, Malarone is a patented drug and so it's offensively expensive.
Extra shots you might want are Japanese Encephalitis and Rabies but -

Danny and Emily, not much help with the malaria shots but just wanted to say we spent the day in Vung Tau yesterday and had a lovely time. Its a really nice place with great beaches. It has quite a few expats there and i didnt see one mosquito all day.
