Oil prices were little changed on Tuesday, trapped in the narrow trading band of the past three weeks as investors gauged hopes for a recovery in oil demand against fears of new lockdowns due to a growing number of coronavirus cases.
Prices were offered some support by positive news on the development of vaccines as drugmakers and medical institutions rush to find a way to counter the world's worst health crisis in a century.
Brent futures were up 15 cents, or 0.4 per cent, at $43.43 by 0117 GMT, while West Texas Intermediate (WTI) edged up 2 cents to $40.83.
