US President Donald Trump claims America could have a coronavirus vaccine by October. On Monday, Mr Trump said the US would have this "wonderful vaccine" very soon. "We will end the pandemic under Operation Warp Speed," he said. "We have pioneered ground-breaking therapies and reduced the fatality rate by 85 per cent since April. Under my leadership, we will produce a vaccine in record time. "Joe Biden and his new liberal running mate will destroy this country and would destroy the economy, and should immediately apologise for their anti-vaccine rhetoric that they are talking right now. "This vaccine could have taken two to three years but instead it is going to be done in a very short period of time, and we could even have it during the month of October. "The vaccine will be very safe and very effective. The people of the world will be very happy." Mr Trump also touched on the fallout the US has had with the World Health Organisation, saying the UN agency had become "much better ... much nicer" to the US. He later raised the idea of separating the US and Chinese economies, suggesting the US would not lose money if the two countries no longer did business. "So when you mention the word decouple, it's an interesting word," he said. "We lose billions of dollars and if we didn't do business with them we wouldn't lose billions of dollars. It's called decoupling, so you'll start thinking about it."
