the twinrix 720/20 can be given at 0 days, 7 days and 21 days then you need a 4th at 12 months post initial dose. there is no adverse effects from this quick schedule that arent associated with giving normally. and that is the reccomended quick dose for travel reasons

tetnus will be fine if about 5 years ago.

and it is true a 4th tablet taken within 7 dasy has been shown to have lower incidences of typhoid.. but that would be your choice, the national health and medical research council reccomnd 3 dises but a 4th is optional..
