WASHINGTON – Senior U.S. officials will begin receiving coronavirus vaccines this week as part of updated federal continuity of government plans that now include terrorism and pandemics as threats to the nation, and its leaders.The effort comes after President Donald Trump tweeted on Sunday that White House aides should receive the COVID-19 vaccine “somewhat later in the program.” Still, doses are expected to be administered at the White House, Capitol Hill and other facilities within the week, according to senior administration officials.Trump’s statement about moving more slowly was only expected to affect priority vaccination for a small subset of the hundreds, if not more, officials who are to be inoculated with the Pfizer vaccine,.
