The Mercedes driver is 34 points ahead of Vettel heading into Sunday's Japanese Grand Prix with 125 available in the remaining five races this year.
Hamilton said: "I am under no illusion. I might have the nail a little bit in, but I need to keep hammering it.
"It is not done until there is no more to push it in."
Hamilton has gained 31 points on Vettel in the past two races after problems for the German and his Ferrari team.
"There are so many points available and you have seen other years where things swing," Hamilton added.
"The pendulum can swing. I am hoping if it starts to swing the other way we have enough force to push it back to where it should be."
Ferrari have been quicker than Mercedes in the past two races but both their cars crashed out together at the first corner in Singapore and Vettel finished fourth in Malaysia after starting from the back because of an engine problem.
Asked to rate his chances of overhauling Hamilton, Vettel said: "We have a chance. I tend not to rate many things. I think there is a chance and we make sure we use it.
"We are behind so it depends on what Mercedes are doing. We just have to do our best and we need to score much more than them. How we achieve it doesn't matter as long as we do achieve it."
