Why can't there be just one dose like the measles where you get one shot and you're immunized? Is there any possibility of getting the benefits of all four doses in only one?

The polio vaccine is no longer given orally in the US but intramuscularly. (This is to prevent a child from getting Polio from the vaccine or transmitting it). IT is now part of the Pediarix vaccine which combines the DPT(Diptheria, Pertussis and Tetnus) and Hep B vaccine with the Poli vaccine.
Since it is a killed vaccine (unlike the MMR which is a live virus vaccine) it needs to be given many times to induce memory.
Actually with the Measles vaccine (part of the MMR) it needs to be given twice (at 1 year and 5 years) to ensure that immunity is obtained

Polio is given in divided doses over a period of time, as is DTaP, Hib, and a few other immunizations. The total amount of the dosages would be too much at one time and the schedule of divided dosages allow the body to develop immunity to the diseases for which they're given. The schedule also allows for immunizing, especially children, to begin early for all the childhood diseases for which vaccines are available-this is important because otherwise kids would be vulnerable to not only polio but the other childhood diseases.
