Trump pledges a Covid-19 vaccine by end of 2020 — without acknowledging the scientific uncertainty
WASHINGTON — President Trump on Thursday pledged a Covid-19 vaccine would be available by the end of 2020, the most concrete claim he has made yet about the timetable for coronavirus vaccine development.
“We are delivering life-saving therapies, and will produce a vaccine before the end of the year, or maybe even sooner,” he said.
