With a giant snowstorm blanketing the Northeast, the pace of vaccination has slowed somewhat, but the good news is more than 32.2 million doses have been administered in the United States thus far. The Centers for Disease Control and Prevention says 5.9 million Americans have received a second dose. And, at the present pace of 1.3 million needle sticks a day, the U.S. is well above the target of 1 million vaccinations per day.

Now, a third vaccine, by Johnson and Johnson, is available, and while it shows only a 72% efficacy, it has advantages.
