President Donald Trump says the COVID-19 coronavirus outbreak shows the requirement for a superior influenza shot.

Donald Trump told a rally crowd Monday night that he lectured drug executives, visiting the White House to talk about the coronavirus, that they have to diminish annual passings from the flu.

“I told the pharmaceutical companies you have to do a little bit better job on that vaccine,” Trump said in Charlotte, North Carolina.

“You lose 27,000 people to the common flu. It can be much more,” Trump said. “One year it went up to 100,000 people. I said nobody told me that. Nobody knew that.”

Trump has invoked the flu before as he tries to quiet terrified markets and public worry about the coronavirus. On Monday, the Dow bounced back from seven days-long nosedives. Trump commended the about 1,300 points, the greatest single-day gain.

“You know, our opponents said, ‘Oh, maybe he’s in trouble, maybe the economy.’ They’ll do anything,” Trump said. He jeeringly added: “I’m sure they were thrilled. You think our opponents were thrilled when they saw the stock market today?”

Since the end of the week, six individuals have died from the virus in the US. There are instances of obscure birthplace in California and Washington state, and specialists state there might be several undetected contaminations.

A White House gathering of drug executives Monday included GlaxoSmithKline CEO Emma Walmsley, Gilead CEO David O’Day, and Johnson & Johnson chief scientific officer Paul Stoffels.

Trump said at the rally that there might be a vaccine “relatively soon” and a treatment “even sooner” for the coronavirus.

Internationally there are about 90,000 cases of the coronavirus, with more than 3,000 passings. The vast majority are in China.
