Watching and listening to this: https://www.c-span.org/video/?507423-1/vice-president-pence-receives-covid-19-vaccine

A couple of observations so far:

At ~3:20 "…vaccine is a two doze series, so that means you'll need to come back in 21 days for the second one."

Assuming this video was shot today on 18th of december, 21 days from now is 7th of january.

At ~4:31 "… we gather here today at the end of a historic week to affirm to the American people that hope is on the way." Hope=8+15+16+5=44
