President Trump vowed to reopen the country's economy "vaccine or no vaccine" at a White House event Friday on vaccine research.
"Vaccine or no vaccine, we're back," the president said. "And we're starting the process, and in many cases they don't have vaccines. A virus or a flu comes, you get through it -- haven't seen anything like this in 100 years, 1917. But you fight through it, and people sometimes, we don't know yet, it looks like they become immune."
"What we'd like to do is the vaccine, and hopefully we'll be successful by the end of the year."
