Will it be all right after the rabies vaccine?

There is no need for rabies vaccine at present. You have passed the incubation period safely.

Rabies vaccine can't last for 20 years.

Look at the information below.

The incubation period of rabies fluctuates the most, ranging from 6 days, 12 days to 1 year or more. It usually occurs within 2 weeks to 3 months, 1 year is 99%, 1 year or more 1%. But it is very rare that rabies exceeds 1 year and a half.

The protection period of rabies vaccine is 6 months (there is no difference between imported and domestic), and the first three months after the last injection is the absolute protection period, when the antibody is at its peak. After three months, the antibody dropped rapidly. Therefore, if you are bitten by a dog again in the first three months, you don't have to take the vaccine. If you are bitten by a dog within six months, you can strengthen two stitches. Re-injection for more than six months (to adapt to various rabies vaccines).
