Singapore, Mar 23: Oil prices fell at the open in Asia on Monday after a trillion-dollar Senate proposal to help the coronavirus-hit American economy was defeated and death tolls soared across Europe and the US.

US benchmark West Texas Intermediate initially tumbled more than three percent but then pulled back some ground to trade 1.5 percent lower, at $22 a barrel.

Brent crude, the international benchmark, fell 4.9 percent to $25 a barrel.

Prices have fallen to multi-year lows in recent weeks as lockdowns and travel restrictions to fight the virus hit demand, and top producers Saudi Arabia and Russia engage in a price war.

The latest drop came after a trillion-dollar Senate proposal to rescue the US economy was defeated after receiving zero support from Democrats, and with five Republicans absent from the chamber because of virus-related quarantines.

The bill had proposed funding for American families, thousands of shuttered or suffering businesses and the nation's critically under-equipped hospitals.

Coronavirus deaths soared across Europe and the United States at the weekend despite heightened restrictions.

The death toll from the virus -- which has upended lives and closed businesses and schools across the planet -- surged to more than 14,300 Sunday, according to an AFP tally.

AxiCorp chief markets strategist Stephen Innes said that "total demand devastation" had set it.

"Oil markets collapsed out of the gate this morning as prices react... to stringent containment lockdown measures," he said.

Paris, Jul 20: Two coronavirus vaccine candidates have proven safe for humans and produced strong immune reactions among patients involved in separate clinical trials, doctors said on Monday.

The first trial among more than 1,000 adults in Britain found that the vaccine induced "strong antibody and T cell immune responses" against the novel coronavirus.

A separate trial in China involving more than 500 people showed most had developed widespread antibody immune response.

The studies, published in The Lancet medical journal, constitute a major step on the road towards a COVID-19 vaccine that is effective and safe for widespread use.

The authors of the studies said that they encountered few adverse side-effects from the vaccine candidates.

However, they cautioned that more research was needed, particularly among older adults, who are disproportionately at risk of dying of COVID-19.

Co-author Sarah Gilbert from the University of Oxford said the results "hold promise".

"If our vaccine is effective, it is a promising option as these types of vaccine can be manufactured at large scale."
