The measles vaccine was introduced in 1963, and as the CDC points out, it reduced measles deaths from about 400-500 per year to 1 or 2 - although there were epidemic years in 1970-72, 1976-78, and 1989-91.
According to the Vital Statistics of the United States, in the 63 years prior to the measles vaccination introduction, death rates declined from 13.3 per 100,00 to 0.2 per 100,000.

Please keep in mind that typhus and typhoid are often water born diseases. Strides in public health have reduced the incidence of these diseases considerably. TB is in fact on the rise again, and many strains are now immune to the drugs once used to treat them. This is true here in the US and even more so in the third world. Finally, doctor report the drop in scarlet fever to be in part due to better diagnostics now available. Measles and diptheria among others were often misdiagnosed as scarlet fever.
